The RJ45 Adaptor provides a simple way to connect two compatible copper Ethernet cables together, allowing an existing network cable connection to be extended without replacing the entire cable run.
Its compact 15.8 × 21 × 34.3 mm design makes it a convenient solution for network changes, equipment relocation and situations where an existing Ethernet cable does not quite reach the required connection point.
For a detailed explanation of how these adaptors work and when to use them, read the fibreSales guide: RJ45 Couplers Explained.
An RJ45 adaptor, commonly called an RJ45 coupler, creates an inline connection between two Ethernet cables.
Instead of replacing an existing cable simply because it is too short, an installer can connect a second compatible cable using the adaptor. This creates a convenient extension while retaining RJ45 connections at each end.
Copper Ethernet patch leads commonly use RJ45 connectors for connections between switches, routers, patch panels, computers and other network equipment. Fibre Sales
One of the most useful applications for an RJ45 adaptor is extending an existing network connection.
For example, an adaptor can provide a practical solution when:
Simply connect the existing RJ45-terminated Ethernet cable to one side of the adaptor and the compatible extension cable to the other.
Choose an RJ45 adaptor when you need a straightforward inline connection between two compatible Ethernet cables and replacing the complete cable is unnecessary or impractical.
For permanent structured cabling installations, however, consider the complete cabling design and applicable installation requirements rather than automatically using multiple inline couplers.
Measuring only 15.8 × 21 × 34.3 mm, the adaptor takes up very little space within a network installation.

Whether to use a coupler or replace the complete Ethernet cable depends on the installation.
| Situation | Practical Approach |
|---|---|
| Existing patch cable is slightly too short | RJ45 adaptor may provide a convenient extension |
| Equipment has moved | Extend with a compatible cable and adaptor where appropriate |
| Temporary network change | RJ45 adaptor can provide a simple solution |
| Damaged Ethernet cable | Replace the damaged cable rather than using a coupler to hide the fault |
| New permanent structured cabling | Design and install the cabling correctly for the required application |
An adaptor provides convenience, but it should not become a substitute for correcting damaged or poorly designed cabling.
The adaptor joins the cables physically; however, the overall connection still depends on the Ethernet cables used.
When extending a network cable, select an extension cable appropriate for the existing network and application.
For many commercial Ethernet installations, fibreSales Cat6 Patch Cables provide factory-terminated RJ45 connections. fibreSales’ published networking resources identify Cat6 as widely used for modern commercial Ethernet installations. Fibre Sales
RJ45 adaptors can prove useful for:
Use compatible Ethernet cabling suitable for the network application.
An adaptor is useful when an extension is genuinely required. Avoid adding unnecessary connection points simply because a coupler is available.
Replace damaged Ethernet cables rather than treating the adaptor as a repair for compromised cable.
After extending the cable, verify the connection with an appropriate Cable Tester.

This compact RJ45 adaptor provides a straightforward option when two compatible Ethernet cables need to be joined to extend an existing network connection.
It connects two compatible RJ45-terminated Ethernet cables, allowing an existing network cable connection to be extended.
The terms are commonly used for the same type of inline Ethernet connection product. The networking industry commonly uses RJ45 terminology for the modular connectors fitted to Ethernet cables. Fibre Sales
Yes. Extending an existing Ethernet cable is one of the primary applications for this product.
No. The adaptor connects compatible cables that already have RJ45 connectors fitted.
It measures 15.8 × 21 × 34.3 mm (H × W × D).
A damaged Ethernet cable should be replaced. Do not use an adaptor merely to conceal or work around cable damage.
Yes. Testing the completed connection helps identify basic wiring or connection problems before the network link goes into service.

Extend an existing copper Ethernet connection without replacing the entire cable run.
With compact dimensions of just 15.8 × 21 × 34.3 mm, the RJ45 adaptor provides a simple inline connection between two compatible Ethernet cables.
The RJ45 Adaptor offers a compact and straightforward way to join two compatible Ethernet cables when an existing network connection needs additional length.
Rather than re-terminating or immediately replacing the complete cable, installers can use the adaptor to create an inline extension where appropriate. Its compact dimensions also make it convenient for network modifications, equipment moves and general Ethernet maintenance.
