40-Pack Gigabit RJ45 Couplers

This 40-pack supplies black female-to-female RJ45 couplers for joining two Ethernet cables into a longer run. Each unit is built with gold-plated copper contacts, a shielded PCB and a snap-in retaining clip to maintain a secure, corrosion-resistant link. The couplers meet Category 6 performance and the TIA/EIA 568-C.2 standard with RoHS compliance. They support data rates up to 1 Gbps across Cat5 through Cat8 cabling.

Installers extending existing cable runs

Technicians who need to bridge two shorter patch cords in home, office or lab environments will find the bulk quantity convenient. The plug-and-play design requires no drivers or tools, making it suited for quick repairs or temporary extensions. Buyers who require keystone-jack mounting should look elsewhere, as these couplers are not compatible with keystone panels. They also cannot be used with RJ11 telephone cables or any non-RJ45 connector type.

Category 6 rated inline coupler

The single specification that determines suitability is the Category 6 performance rating with TIA/EIA 568-C.2 compliance. This confirms the coupler can handle gigabit-speed signals on Cat5, Cat5e, Cat6, Cat6a, Cat7 and Cat8 cables without signal degradation. If your installation demands a higher certified category or a keystone form factor, this part will not meet that requirement.

Questions about this item

What throughput limit appears first when the coupler is used continuously at gigabit speeds?

The coupler meets Category 6 performance and supports up to 1 Gbps, so the 1 Gbps ceiling is the first limit you reach under sustained load.

How much heat or noise does the coupler generate when running all day?

It is a passive component with no fan or power draw, so it produces no noise and negligible heat during continuous operation.

Which cables must I already have for these couplers to work?

You need two Ethernet cables with RJ45 plugs — Cat5, Cat5e, Cat6, Cat6a, Cat7 or Cat8 — because the coupler is female-to-female and not compatible with RJ11 or keystone jacks.
