Gold-plated connector contacts
The EZYUMM Ethernet Coupler is a three-pack of female-to-female RJ45 extenders with a supplied rating of 4.7. Its main appeal is straightforward cable extension at a budget-conscious entry point: two Ethernet cables connect through one coupler without replacing the existing patch leads. The listing supports Cat5, Cat5e, Cat6, and Cat7 cables and states a transfer rate of up to 1 Gbps.
Pros
- Affordable three-pack
- No drivers required
- Broad cable compatibility
- Toolless installation
- Compact inline design
Cons
- Rated only to 1 Gbps

Construction details reinforce its usefulness for ordinary home and office networks. The contacts are described as gold-plated, and the plug-and-play format requires no tools, software, or drivers. Its stated reach of up to 328 feet applies to the combined cable run, while backward compatibility with 1000 Mbps, 100 Mbps, and 10 Mbps networks is designed to cover common Ethernet applications.
The principal limitation is that this is not positioned as a high-bandwidth 10 Gbps solution. Actual network performance will also depend on the connected cables, devices, and installation. It is an inline adapter rather than a keystone jack, so it does not provide a structured-cabling termination for a faceplate. Even with those qualifications, the three-pack provides useful flexibility for several short extension projects.
This is a strong choice for a household, office, or game-room setup that uses Gigabit Ethernet and simply needs extra cable length. Choose it when straightforward compatibility, a three-coupler pack, and tool-free installation matter more than 10 Gbps capability or wall-plate integration. Among budget-oriented inline couplers, it is one of the most balanced options in the list.
Practical Cable Extension
The inline female-to-female design lets existing cables remain in place. Connecting one lead to each end immediately creates a longer route, making it useful when a router or network port is slightly beyond the reach of a single patch cable.
Broad Everyday Compatibility
Support for Cat5, Cat5e, Cat6, and Cat7 means the coupler can bridge several generations of Ethernet cable. Its stated Gigabit speed is appropriate for many common routers, computers, televisions, and other networked devices.

This RJ45 Cat6 Coupler comes as a ten-pack and carries a supplied rating of 4.7. It is designed to join two shorter Ethernet cables while retaining compatibility with Cat5, Cat5e, Cat6, and Cat7 network cable. The inline female-to-female format gives installers a simple way to extend a connection without purchasing a completely new longer run.
Pros
- Ten-piece multipack
- Gold-plated contacts
- Metal shielding reduces interference
- Secure retaining clip
- Tool-free connection
Cons
- No stated 10 Gbps rating
- Larger quantity may be unnecessary
We may earn a commission when you buy through this link, at no additional cost to you.
The listing emphasizes pure-copper, gold-plated contacts and a full-metal shielding layer intended to support signal strength and reduce interference. Nickel-plated contacts and a snap-in retaining clip are also listed as protections for a secure, corrosion-resistant connection. The coupler uses ABS housing designed to tolerate high and low temperatures, which is useful in varied installation environments.
Its strongest trade-off is quantity. Ten couplers may be ideal for an installer handling multiple endpoints, but a household connecting one device may have several unused. The product description focuses on stable transmission and Category 6 performance rather than advertising a 10 Gbps maximum, so buyers seeking a clearly stated multi-gigabit specification should verify their equipment and cable requirements.
This ten-pack suits network technicians, offices, classrooms, home labs, and anyone who expects to need more than one extension point. It is especially attractive when one purchase must supply several keystone-style or inline connections. For a single straightforward home connection, a smaller pack may be more convenient, but the included protective and shielding features make this a well-rounded option for repeated installations.
Built for Repeated Connections
The snap-in retaining clip helps keep both patch leads seated, while the durable housing and plated contacts address the wear expected when connectors are inserted and removed during routine network maintenance.
Useful Project Quantity
Ten units allow an installer to create several extension points without purchasing separate couplers. That makes the pack convenient for offices, structured wiring projects, and households with multiple short Ethernet runs.

Up to 1 Gbps transfer
Tested plated contacts
The four-piece RJ45 Inline Coupler is a Cat5-compatible extension option with a supplied rating of 4.7. It connects two short Ethernet cables through a female-to-female inline design and is listed as compatible with Cat5, Cat5e, Cat6, and Cat7 wiring. The stated performance reaches up to 1 Gbps, aligning it with common Gigabit Ethernet networks.
Pros
- Reasonable four-pack quantity
- Metal shielding included
- No drivers required
- Corrosion-resistant contacts
- Works across cable categories
Cons
- Gigabit speed only
- Inline rather than keystone format
We may earn a commission when you buy through this link, at no additional cost to you.
The connector uses eight-core pure-copper, gold-plated contacts, while the nickel-plated contact area is said to withstand more than 10,000 insertion cycles. A full-metal shielding layer is included to help reduce signal interference, and the ABS housing is designed to remain stable across high and low temperatures. Installation requires only plugging one RJ45 cable into each side.
Compared with larger multipacks, four couplers offer a moderate amount of flexibility without creating as much unused inventory. The tradeoff is that its stated speed ceiling is lower than products explicitly marketed for 10 Gbps. It also cannot be installed as a permanent keystone-style wall outlet, so it is better suited to temporary or accessible inline cable routing.
This coupler is a sensible choice for users extending ordinary Gigabit connections at home, in an office, or around a server-room installation where several points may be needed. It combines useful shielding, a manageable pack size, and broad compatibility. Choose it when stable Gigabit performance is the priority and 10 Gbps is not required.
Signal-Focused Contact Design
Gold-plated eight-core contacts are intended to preserve a consistent connection, while the full-metal shield helps limit interference. These features make the inline coupler relevant where stable everyday networking matters more than a specialized wall-plate format.
Installation Without Tools
No drivers or wiring changes are needed. The process is simply to seat both RJ45 connectors until the retaining mechanism holds them in place, making the product approachable for non-specialists.

The BENFEI RJ45 Inline Coupler is a five-pack with a supplied rating of 4.7 and one of the strongest balance of stated performance and compatibility in this guide. It is intended for connecting two Cat5, Cat5e, Cat6, or Cat7 Ethernet cables, and its listing claims support for transfer rates up to 10 Gbps when suitable higher-category cables are used.
Pros
- Strong stated speed capability
- Five-piece multipack
- Secure snap-in clip
- Corrosion-resistant contacts
- RoHS compliant
Cons
- 10 Gbps requires suitable cables
- Not a wall-plate jack
We may earn a commission when you buy through this link, at no additional cost to you.
Nickel-plated contacts and an easy snap-in retaining clip are intended to keep the connection secure and resist corrosion. The coupler meets Category 6 performance under the stated TIA/EIA 568-C.2 standard and is RoHS compliant. Its inline arrangement means it can be placed wherever two patch leads meet without requiring a faceplate, punch-down tool, or complex termination.
The key qualification is that a coupler cannot exceed the capabilities of the cables and devices in the chain. A 10 Gbps claim is most relevant with compatible Cat6 or Cat7 cabling, appropriate network hardware, and a properly configured link. For older Cat5 networks, the coupler still provides the physical connection needed to extend the run, although the network may operate at the lower capability of that cable.
This is our top overall recommendation for buyers who want broad compatibility, a useful five-unit quantity, and a product that can accommodate both standard Gigabit networks and properly equipped 10 Gbps setups. It works for home offices, studios, gaming areas, and small business environments where multiple extension points may be useful.
Ready for Higher-Speed Networks
The stated 10 Gbps capability makes this coupler more adaptable than options limited to Gigabit Ethernet. That advantage matters when the existing network uses newer cable and hardware, while standard Cat5 installations continue to work through the same simple connection method.
Reliable Inline Connection
The retaining clip supports a stable physical connection between both leads. Nickel-plated contacts are intended to limit corrosion, making the adapter suitable for long-term use in a maintained network setup.

We may earn a commission when you buy through this link, at no additional cost to you.
Its installation is conventional: connect one RJ45 lead to each female end of the coupler. The product requires no drivers, and nickel-plated contacts with a snap-in retaining clip are designed to create a secure, corrosion-resistant connection. The inline jack is stated to meet Category 6 performance and comply with TIA/EIA 568-C.2 and RoHS requirements.
The main ambiguity is its speed positioning. Although the coupler supports very high-category cables, the supplied description only promises high-speed data transfer rather than giving a specific 10 Gbps maximum. Users should therefore consider the network equipment, existing patch cables, and intended application—not just the Cat8 label—when judging expected performance.
This six-pack is well suited to homes with several Ethernet endpoints, gaming rooms, offices, and media installations. It is especially attractive for users who want a single adapter type to work across many cable categories. The black finish also gives it a discreet appearance around desks and entertainment equipment, although the inline form does not disappear into a wall plate.
One Adapter Across Generations
Compatibility from Cat5 through Cat8 makes the pack useful in mixed environments. A user can retain older patch leads in one location and use newer high-category cables elsewhere without changing the adapter type.
Useful for Entertainment Networks
The product listing specifically mentions routers, modems, PS5, and Xbox use cases. It is a practical connector for living-room or game-room cable runs where the installed Ethernet lead does not quite reach the intended device.

The IIABC RJ45 Ethernet Coupler is a three-pack with a supplied rating of 4.7. It provides a female-to-female inline connection for Cat5, Cat5e, Cat6, and Cat7 cables and is intended to solve the common problem of two individually usable Ethernet leads that do not reach far enough together.
Pros
- Manageable three-pack
- Gold-plated pure-copper contacts
- Full-metal shielding
- No drivers required
- Retaining clip included
Cons
- Limited to 1 Gbps
- No structured-wall integration
We may earn a commission when you buy through this link, at no additional cost to you.
The listing highlights eight-core pure-copper, gold-plated contacts and a full-metal shielding layer for signal transmission and interference reduction. ABS housing is described as resistant to high and low temperatures, while nickel-plated contacts and the snap-in retaining clip support a secure connection. Installation is plug and play, with no software or drivers required.
As with other inline options, the adapter is limited by the slowest component in the connection. Its stated Gigabit maximum is sufficient for many homes and offices but will not unlock 10 Gbps service on compatible modern equipment. It also does not provide a flush-mounted keystone connection for a faceplate or patch panel, so cable management may be less tidy in permanent structured installations.
This is a good option for a small number of basic extension points, particularly where Cat5 or Cat5e is already installed and no more than Gigabit performance is needed. The three-unit count avoids unnecessary bulk while retaining some installation flexibility. It is most attractive to users wanting a straightforward, shielded, tool-free solution without a complicated termination process.
Shielded Inline Connection
The combination of gold-plated contacts and a full-metal shield is intended to support stable data transfer. That makes the coupler relevant for users who want a little more signal-focused construction than a basic unshielded adapter.
Solve the Short-Cable Problem
Rather than discarding a usable patch cable, a user can connect it to another suitable lead through the coupler. This is especially convenient for temporary setups and single-room network extensions.

We may earn a commission when you buy through this link, at no additional cost to you.
Its eight-position, eight-contact connector uses full-copper conductors with gold plating and is stated to support 10, 100, and 1000 Mbps Ethernet. The slim shape allows up to six coupler ports within a suitable wall plate, depending on the plate design. Buyers can create additional network points using ordinary patch cables without performing punch-down terminations or crimping new connectors.
The trade-off is narrower compatibility than several full-size inline products. It is not listed for Cat7 or Cat8 cable, and the wall-plate option requires a compatible keystone opening. Its stated performance centers on Gigabit Ethernet, so it is best suited to Cat5e and Cat6 networks rather than high-bandwidth installations requiring 10 Gbps.
Choose the Rapink pack when neat wall-plate integration is more important than maximum transfer speed. It is particularly useful for home network builders, installers creating extra rooms or outlets, and technicians who prefer reusable patch-cable connections. For basic inline extension, many alternatives are simpler, but this one adds a more permanent and organized installation option.
Cleaner Permanent Network Outlets
A keystone-style body can sit in a compatible faceplate or blank patch panel. This creates a more organized network point than leaving a connector exposed along a wall, baseboard, or desk.
Avoiding Punch-Down Work
The coupler accepts standard RJ45 patch leads, so installers can work with existing cables instead of terminating new wire. That can simplify the process of adding or reorganizing structured network points.

We may earn a commission when you buy through this link, at no additional cost to you.
Compatibility extends from Cat5 and Cat5e through Cat6, Cat7, and Cat8. The listing claims stable network extension up to 328 feet and positions the product for gaming, 4K streaming, large file transfers, routers, computers, smart televisions, consoles, and servers. Its signal-integrity protection is intended to maintain a stable connection across home, office, and multi-room environments.
Although the stated features are appealing, the supplied listing does not mention a specific Category 6 or TIA/EIA compliance standard. The 328-foot and 10 Gbps claims should therefore be understood as product specifications rather than guarantees for every cable combination. Real performance depends on the category and quality of the two connected patch leads, the devices, and the intervening environment.
This is the premium recommendation for users who want an aluminum-bodied coupler and explicitly stated 10 Gbps support, particularly with newer Cat6, Cat7, or Cat8 wiring. The five-unit pack suits a high-end home, small office, or media installation. Buyers using only older Cat5 wiring can still use the connector, but their ultimate speed will remain constrained by the rest of the network.
Premium Housing Advantages
Aluminum alloy is presented as a durable, heat-dissipating alternative to a basic plastic shell. It may be particularly appealing in installations where the coupler is visible or handled during routine equipment changes.
Headroom for Modern Networks
Stated 10 Gbps support and support for Cat8 provide useful headroom for modern, high-speed wired networks. The coupler can serve as the physical link between newer patch cables without requiring a different adapter format.

- Cat6A cable compatibility
- Gold-plated eight-contact contacts
- ANSI and TIA compliant design
- Tool-free inline installation
Cons
- Requires compatible keystone opening
- Not suitable for Cat7 or Cat8
We may earn a commission when you buy through this link, at no additional cost to you.
Gold-plated 8P8C contacts and an ANSI/TIA/EIA 568-C.2-compliant design are highlighted for stable Gigabit performance. The title advertises 10 Gbps capability, although the product description specifically discusses stable Gigabit transmission for everyday networking. Buyers should therefore evaluate the exact cable and hardware used rather than assuming every connected combination will operate at the maximum stated rate.
Installation requires no punching, wiring, or crimping. Two standard RJ45 patch leads plug into opposite sides of the coupler, allowing it to be used inline or placed in a compatible keystone opening. The compact housing is intended for clean cable management in tight spaces, including connections for routers, switches, PCs, consoles, printers, and smart televisions.
This is an excellent choice for installers and advanced home-network builders who value recognized listing standards, broad compatibility with Cat6A patch leads, and a keystone-style form factor. It is less appropriate for a user who needs a loose inline adapter for Cat7 or Cat8. The five-pack balances professional organization with enough units for several network points.
Standards-Oriented Connection
The UL-listed designation and stated adherence to ANSI/TIA/EIA 568-C.2-oriented construction are useful details for buyers who prioritize formal network-installation standards. Gold-plated contacts support dependable repeated connections.
Convenient Patch-Cable Connection
Existing patch leads can be connected without punch-down tools. This makes the coupler useful for organized structured cabling and for reorganizing router, switch, or device connections around tight spaces.

Modular inline design
The StarTech.com Cat5e RJ45 Modular Inline Coupler is a two-pack with a supplied rating of 4.4. It has a deliberately focused purpose: joining two Cat5e RJ45 network cables to extend the length of an existing patch cable. Dual female RJ45 connectors provide the familiar inline connection without the need to replace installed cabling.
Pros
- Purpose-built for Cat5e
- Simple two-pack quantity
- Extends existing patch cables
- Dual female RJ45 connectors
- No rewiring required
Cons
- Narrow Cat5e focus
- Small two-piece pack
We may earn a commission when you buy through this link, at no additional cost to you.
The modular design is straightforward. Plug one cable into each end of the coupler, confirm that both retaining clips are seated, and test the connection with the intended router, switch, computer, or other Ethernet-enabled device. Because the product is specified for Cat5e, it is a natural fit for users who know their patch cables are Cat5e and do not need broader category support.
Its limitations are mainly about scope. A two-unit pack provides less flexibility than the three-, four-, five-, six-, and ten-piece options elsewhere in this guide. The listing also gives less detail about shielding, housing materials, and maximum transfer rate than several competing products, so buyers seeking evidence of premium construction or multi-gigabit specifications may prefer a more fully specified alternative.
This coupler is best for a small, straightforward repair or extension involving known Cat5e cabling. It may suit a homeowner keeping an existing patch cable in service or an installer who knows exactly how many junctions are required. For broader cable compatibility, a larger multipack with detailed performance specifications is the safer general recommendation.
Focused Cat5e Use
The product is tailored to Cat5e patch leads and does not attempt to compete with the broader category support of several alternatives. That focus can simplify purchasing when the type of cable in hand is already known.
Extend Without Rewiring
Two existing cables can be joined rather than replacing the entire run. This is useful for temporary connections, repositioned equipment, and installations where rewiring would be inconvenient.

Buying Guide – How to Choose the Best Cat5 to Cat5 Coupler
The right coupler depends on your cable category, network speed, installation style, and how many connection points you need. Use the following factors to narrow the field before comparing the final options.
Cable Category Compatibility
Start by identifying the category of both Ethernet leads that will meet at the coupler. Every product in this list supports Cat5, but some also cover Cat5e, Cat6, Cat7, or Cat8. A Cat5-specific installation can use a wider-range coupler, although matching the coupler to the lowest cable category keeps expectations realistic. The StarTech.com model is the most narrowly focused, while the ZUZONG and Dacrown products advertise the broadest category coverage.
Required Network Speed
A coupler does not create additional bandwidth. The connection can only perform as quickly as the cables, devices, switch, router, and pathway allow. Several products explicitly state up to 1 Gbps, while the BENFEI, Dacrown, and Cable Matters listings include higher-speed claims. For a standard home network, a Gigabit-rated coupler is usually sufficient, but users with compatible 10 Gbps equipment should review the exact speed language and cable requirements.
Inline Versus Keystone Style
Inline couplers sit directly between two cables and are the easiest option for a desk, entertainment center, or temporary run. Keystone-style couplers are intended to fit a compatible wall plate, faceplate, or blank patch panel. The Rapink and Cable Matters products are particularly relevant to structured installations, while the remaining options favor general inline use. A keystone model cannot be assumed to fit every outlet box or plate.
Connector and Housing Construction
Look for details that support a stable connection, such as nickel-plated or gold-plated contacts, a snap-in retaining clip, shielding, and a housing suited to the installation environment. Gold-plated contacts appear in several listings, while full-metal shielding is highlighted by the RJ45 Cat6 and IIABC options. The Dacrown product uses an aluminum alloy shell for a more premium feel and stated heat dissipation. No single construction feature overrides the need for a secure fit and compatible hardware.
Pack Size and Spare Coverage
Pack quantity should reflect both immediate use and likely future needs. Two or three couplers suit a household fixing one or two short runs, while five-, six-, and ten-packs serve installers or users with several endpoints. A larger multipack can be useful for maintenance, but it may leave unnecessary adapters unused. Consider whether the pack includes inline units, keystone units, or a mixture, because the formats are not directly interchangeable in every installation.
Shielding and Interference Control
Shielding can be helpful in environments with nearby electrical equipment, bundled cables, or longer runs, although the complete cable installation remains important. Products with stated full-metal shielding include the RJ45 Cat6, RJ45 Inline, and IIABC couplers. The others may still provide useful contact plating and stable connections. If your cables are unshielded, or your route is short and isolated, shielding may be less consequential than fit, compatibility, and installation convenience.
Installation Convenience and Cable Management
Every product listed avoids software installation, and all use standard RJ45 connections. A full-size inline coupler can be left accessible for quick troubleshooting, while a keystone-style model can provide a cleaner permanent installation. Consider bend radius, available space, the location of the retaining clips, and whether the cable will cross a walking area. A tidy installation reduces the chance of accidental disconnection and makes future network maintenance easier.
Standards and Listed Specifications
Formal standards and certification details can matter in professional or structured-cabling environments. The BENFEI, ZUZONG, RJ45 Cat6, RJ45 Inline, and Cable Matters products reference Category 6 or TIA/EIA 568-C.2 performance, while Cable Matters is explicitly UL listed. These details add useful context, but buyers should still verify the actual cable category and intended network speed. Marketing language does not override the limitations of the connected equipment.
How to Use and Care for Your Cat5 to Cat5 Coupler
Begin by identifying the two Ethernet cables that need to be joined and confirm that both use compatible RJ45 connectors and fall within the coupler’s stated category support. Inspect each plug for damaged latches, bent pins, dirt, or an incomplete seating. A clean, undamaged connector is essential because the coupler cannot compensate for a poorly terminated or physically damaged plug.
Unplug the Ethernet connections from the router, switch, computer, game console, television, or other device before joining the leads. Insert one cable fully into one female end of the coupler and the other cable fully into the opposite end. Listen for or feel the retaining click, then check that neither connector can easily slide loose. Reconnect the completed link to the network device and allow a few seconds for the Ethernet connection to negotiate.
After installation, test the link to confirm that the device recognizes a wired connection and that the intended network is reachable. Keep the coupler accessible, avoid sharp bends or crushing pressure on the connected leads, and do not leave it exposed where it may be stepped on or pulled. For a keystone-style unit, seat it securely in a compatible plate or panel and make sure neither cable is strained by the socket.
Frequently Asked Questions
Can a Cat5 to Cat5 coupler increase Ethernet speed?
No. A coupler only joins two cables and cannot make the network faster than the cables, devices, switch, or router already support. The maximum speed is determined by the weakest component in the connection. A coupler advertised for 10 Gbps will still operate at a lower speed if connected with older Cat5 cables or older network hardware.
Will a Cat5 coupler work with Cat5e or Cat6 cables?
It generally can, provided the coupler’s connector dimensions and stated specifications support those cable categories. Most products in this guide support Cat5e and Cat6 even when their names emphasize Cat5. The electrical rating still matters, so a Cat5-specific product should not be assumed to provide the same performance as one specifically rated for Cat6 or a higher category.
Do Ethernet couplers require tools or software?
No. These are plug-and-play passive connections. Insert one RJ45 plug into each end of the female-to-female coupler, then reconnect the joined cable to the network device. No drivers, crimping tool, punch-down tool, or configuration software is required for the inline products. A keystone-style coupler may need a screwdriver to secure it in a wall plate or panel.
How long can the combined Ethernet cable be?
Some products in this guide state extension distances of up to 328 feet, while others do not provide a distance figure. Actual reach depends on the category and quality of both cables, the coupler, interference, and the network standard. Keep the total run within the limitations of the lowest-rated cable and verify the connection after installation.
Are inline and keystone Ethernet couplers interchangeable?
Not always. An inline coupler is designed to sit between two cables as a complete adapter, while a keystone coupler is shaped to fit a compatible faceplate, wall plate, or blank patch panel. A keystone unit may still be used inline if space permits, but its mounting format and dimensions should be checked. An oversized inline coupler will not necessarily fit a standard wall outlet.
Why might an Ethernet connection fail after adding a coupler?
The most common causes are a loose plug, a damaged cable, a connector that was not inserted fully, or a cable category that is unsuitable for the intended speed. Check both RJ45 latches and inspect the contacts for dirt or bending. If the link drops only when the cable is moved, the problem is more likely mechanical than a router or network configuration issue.
Can I use a Cat5 coupler for a gaming console or smart TV?
Yes, provided the console or television has an Ethernet port and the cables and coupler meet the network’s speed requirement. The ZUZONG listing specifically mentions PC, router, modem, PS5, and Xbox use cases, while the other products are general-purpose Ethernet extenders. Check that the coupler does not create a physical stress point at the device.
Should I replace an existing Cat5 cable instead of coupling it?
A coupler can be convenient when replacing the cable would require opening walls, rerouting cable, or disrupting installed equipment. A single continuous cable may offer a simpler connection and avoid an extra junction. If the installation is permanent, the cable is visibly damaged, or it does not meet your required category, replacing the appropriate run is generally the cleaner long-term solution.
Final Thoughts on Choosing the Best Cat5 to Cat5 Coupler
The EZYUMM Ethernet Coupler is the best budget-oriented choice for straightforward Gigabit extensions, while the BENFEI RJ45 Inline Coupler earns the Editor's Choice position for its combination of broad cable compatibility, a stated 10 Gbps capability, and a useful five-pack. The Dacrown RJ45 Ethernet Coupler stands out as the premium selection with aluminum construction, broad category support, and a modern high-speed focus.
The right choice for most buyers depends on the installation. Basic inline users should prioritize clear category compatibility, a secure connection, and an appropriate pack size. Structured-cabling projects should look toward the Rapink or Cable Matters keystone-style options, while users with newer high-speed networks may prefer the BENFEI, Dacrown, or ZUZONG products. Always verify the connector format and the limitations imposed by the existing cables.
Before purchasing, confirm the cable categories, desired transfer rate, mounting style, and number of connection points required. Customer ratings and listing details can change, and product availability or prices may also shift, so review the current product page before placing an order. A well-matched coupler can make an existing network installation more flexible without requiring a complete rewiring project.
