UGREEN 10 Gbps RJ45 Female-to-Female Coupler (15117)

Overview

The UGREEN 15117 is a small passive coupler that joins two network cables with RJ45 plugs into one longer run, for when a cable will not quite reach a PC, TV, router or camera. It carries up to 10 Gbps on a suitable complete link, needs no power or software and has a shielded space-grey aluminium alloy shell.

Is it right for you?

• Suits joining two patch cables between a router or switch and a computer, smart TV, console or printer.
• Suits Cat8, Cat7, Cat6A, Cat6, Cat5e and Cat5 patch cables; the link runs at the speed of its weakest part.
• It is an indoor part with no waterproof, outdoor, burial or in-wall rating, so it does not suit exposed or buried runs.
• It does not extend the overall limit: the two cables plus the coupler must stay within 100 m in total.

Key features

• Two RJ45 female sockets with snap-in retaining clips, so standard plugs latch as they would in a switch.
• Up to 10 Gbps on a suitable complete channel, and backward compatible with 1000, 100 and 10 Mbps.
• Gold-plated copper contacts.
• Metal shield layer inside a PVC inner shell and a space-grey aluminium alloy outer shell.
• Passive and bidirectional: no power, drivers or operating-system dependency.
• About 3.06 x 2.4 x 2.24 cm and 10 g.

What else you need

• Two Ethernet cables with RJ45 plugs. For a 10 Gbps link, both cables, their terminations and the network ports at each end must be 10 Gbps capable.

Before you buy

• It does not amplify, repeat or route the signal, and it does not add distance beyond the normal 100 m channel limit.
• It will not improve a damaged cable, poor termination or slow network port.
• It does not create Wi-Fi, add a port or convert fibre, USB or telephone wiring.
• No PoE (Power over Ethernet) class or wattage is stated for it.
• No waterproof, outdoor, direct-burial, in-wall, plenum, LSZH or fire-resistance rating is stated.
• Every inline join uses up channel margin and adds contact points. If a 10 Gbps link drops to a lower speed, check both cable categories, port capabilities, total length and termination quality. If errors or packet loss rise, shorten the run, remove extra joins and replace any suspect cable or connector.
• Replace the coupler if a socket becomes loose, dirty, bent or unusually hot.
