Extending Ethernet Runs With Ten Couplers

This pack supplies ten RJ45 inline couplers, each joining two patch cables to create a longer run. The 8P8C female-to-female jacks accept Cat7, Cat6, Cat5e or Cat5 cables, so installers can bridge existing links without pulling new wire. Nickel-plated contacts and a snap-in retaining clip keep each connection secure and corrosion-free.

Suited For Simple Extensions.

The couplers meet Category 6 performance per TIA/EIA 568-C.2 and support speeds up to 10 Gbps on compatible cabling. They work well for home offices, lab benches or temporary links where a single joint is needed. Builders certifying a permanent channel to the full standard should note that each added junction consumes insertion-loss budget and may require field testing.

Ten Units In One Pack

The package contains exactly ten black couplers moulded from high-impact, fire-retardant plastic. RoHS compliance confirms the materials meet restricted-substance rules. No tools are required — press the cables in until the clips latch, and the link is live.

Questions about this item

Do the couplers generate any heat or noise when used continuously in a 10 Gbps link?

The passive RJ45 couplers have no active components, so they produce no heat or noise regardless of how long they run at 10 Gbps.

What cables and connectors must I already have to use these 8P8C female-to-female couplers?

You need two Ethernet patch cables terminated with standard RJ45 8P8C plugs — Cat5, Cat5e, Cat6 or Cat7 — to plug into each side of the coupler.

Will these couplers degrade the performance of my existing Cat5e installation?

Each coupler meets Category 6 performance per TIA/EIA 568-C.2, so it will not become the bottleneck on a Cat5e link running at its rated speed.
