What this coupler does

A pack of five black RJ45 8P8C female-to-female straight couplers joins two Cat5 or Cat5e patch cables into a single longer run. The plastic housing measures 3.6 x 1.5 x 2.1 cm and weighs 30 g for the set, making it a compact solution for home or small-office wiring.

Behaviour on a long run

The straight-through wiring preserves the pinout across the junction, so signal integrity depends on the quality of the cables you connect. No active circuitry is present, so performance matches the weakest cable in the chain and adds no latency beyond the extra copper length.

What it replaces and when to use it

This coupler replaces a single pre-terminated long cable when the exact length is unknown or when pulling a new cable through walls is impractical. It is not suited for Cat6 or higher installations that require shielded, impedance-matched connectors, nor for outdoor or PoE loads beyond the cable rating.

Questions about this item

Does the coupler generate any heat or noise when used continuously for long periods?

The plastic coupler has no active components, so it produces no heat or noise during continuous use.

What cables or connectors must I already have to join two runs with this coupler?

You need two Cat5 or Cat5e patch cables terminated with standard RJ45 plugs to connect to the female ports.

Will this black coupler work with older Cat5 cable runs I already have installed?

Yes, the straight 8P8C coupler is designed to extend Cat5 and Cat5e cables without affecting the existing wiring.
