Five-pack RJ45 coupler for cable extension

This five-pack of RJ45 female-to-female couplers joins two Ethernet patch cables to create a longer run. Each unit uses nickel-plated 8P8C contacts inside a fire-retardant housing. The couplers meet Category 6 performance under the TIA/EIA 568-C.2 standard and are RoHS compliant. They support network speeds up to 10 Gbps with Cat7 or Cat6 cabling.

Suits installers joining existing cables.

These inline couplers are built for technicians or home users who need to bridge two terminated cables quickly without re-termination. They work with Cat5, Cat5e, Cat6 and Cat7 cables using standard RJ45 plugs. Buyers who need to crimp fresh ends onto bare wire or who require a shielded coupler for high-EMI environments should look at dedicated crimp tools or shielded alternatives instead.

Category 6 TIA/EIA 568-C.2 verified performance

The decisive specification is compliance with the TIA/EIA 568-C.2 Category 6 standard, which guarantees the insertion loss and crosstalk margins needed for 10 Gbps operation over Cat6 or Cat7 links. Nickel plating on the contacts resists corrosion and maintains signal integrity over repeated mating cycles. This verification confirms the coupler will not degrade a certified Cat6 channel.

Questions about this item

How can I confirm the coupler is delivering up to 10 Gbps after connecting two Cat6 cables?

Verify the link speed in your router or OS network settings shows 10 Gbps, and run a local file transfer or iperf test to confirm sustained throughput matches the rated 10 Gbps capability.

What comes in the 5-pack and do I need to buy any cables separately?

The package contains five RJ45 8P8C female-to-female inline couplers with nickel-plated contacts. You must supply your own Cat5, Cat5e, Cat6 or Cat7 patch cables to join together.

Which version should I choose if I need TIA/EIA 568-C.2 compliant Category 6 performance?

This single 5-pack option already meets Category 6 performance per TIA/EIA 568-C.2, supports up to 10 Gbps, and is RoHS compliant, so no additional version selection is required.
