Extend Ethernet Links

This pack supplies ten RJ45 female-to-female couplers that join two male network cables into a single longer run. Each unit accepts Cat5, Cat5e, Cat6 and Cat7 patch cords and supports data rates up to 1Gbps. The compact body measures 1.65" x .98" x .9" and weighs only .01 ounces. They are finished in black with glossy nickel-plated contacts for corrosion resistance.

No Speed Penalty

The couplers meet the TIA/EIA 568-C.2 Category 6 standard and are RoHS compliant, so signal integrity is preserved across the junction. Eight precisely aligned contacts on each side prevent loss or lag when extending cables up to 328ft total length. The snap-in retaining clips keep connections secure in wall plates, patch panels or direct device links.

Home And Office Networks

Builders who need a quick, tool-free way to lengthen existing copper runs will find these couplers convenient. They suit routers, PCs, laptops, printers and televisions in residential or small-business settings. Installers requiring shielded or outdoor-rated joins, or those needing PoE power delivery beyond the 1A rating, should look at dedicated solutions.

Questions about this item

Will the nickel-plated contacts need any cleaning or replacement over time?

The nickel-plated contacts resist corrosion and the snap-in clip secures the connection, so no routine cleaning or contact replacement is expected.

What limits the 1 Gbps speed when cables run the full 328 ft distance?

The coupler meets TIA/EIA 568-C.2 Category 6 performance, so the 1 Gbps limit is set by the cable category and distance, not the coupler itself.

Does the coupler generate any heat or draw measurable power during all-day use?

It is a passive component with no power input, so it produces no heat and draws zero power regardless of how long it stays connected.
