TeKit RJ45 In-Line Coupler Cat7/Cat6/Cat5e Black 20390

RJ45 In-Line Coupler Cat7/Cat6/Cat5e

This RJ45 coupler joins two Ethernet cables to extend a network run. It accepts Cat7, Cat6, Cat5e and Cat5 patch leads with standard 8P8C plugs. The gold-plated contacts resist corrosion and the retaining clips hold each cable securely. It suits installers and home users who need a quick inline extension without rewiring.

Practical limits of the TIA/EIA 568-C.2 standard

The coupler is verified to meet Category 6 performance under the TIA/EIA 568-C.2 standard. It supports data rates up to 10 gigabit when used with Cat6 or Cat7 cables. Adding any inline connection introduces insertion loss and crosstalk, so total channel length and the quality of both cables affect whether the link achieves the rated speed.

Check your cables and environment before ordering

Ensure both cables use RJ45 8P8C plugs and are rated Cat5e or higher for gigabit traffic. The black plastic housing is UL listed and RoHS compliant, but it is not rated for outdoor or plenum use. Verify the combined cable length stays within your network design limits and that the coupler fits the available space at the join point.
