What this coupler does

The Unique Bargains RJ45 8-pin female-to-female straight coupler joins two network cables to create a longer run without crimping or tools. Each pack supplies five white plastic units measuring 3.7 x 2.2 x 1.6 cm and weighing 33 g total.

Who should use it

Installers who need a quick, tool-free way to bridge Cat5e or Cat6 patch cords in home, office or RV networking will find these couplers convenient. Builders who require shielded connections, PoE passthrough or outdoor-rated housings should look at something else.

Behaviour under load

The plastic housing and straight-through pinout pass Ethernet signals without active electronics, so performance stays consistent as long as the joined cables meet their own category ratings. No heat or signal degradation is introduced by the coupler itself.

Questions about this item

What cable connector type do I need on my existing Ethernet cables to use these RJ45 8P8C female/female couplers?

Your cables must already have standard RJ45 8P8C male plugs; the coupler provides two female sockets to join them pin-to-pin.

Will these plastic straight couplers degrade the signal on a Gigabit Ethernet link that uses all eight conductors?

The coupler passes all eight pins straight through, so it maintains the full conductor path required for Gigabit speeds without active electronics.

After connecting two patch cords with a coupler, how can I verify the link is working at the expected speed?

Check the link LEDs on your switch or NIC; a solid or blinking light at the rated speed (e.g., 1 Gbps) confirms the extended cable is functioning.
