UGREEN Shielded RJ45 Female-to-Female Coupler (20390)

Overview

The UGREEN 20390 is a passive inline coupler that joins two terminated Ethernet leads into one longer run at home, in the office, in a rack or as a temporary extension. It has two shielded 8P8C RJ45 sockets in a compact ABS housing, is rated up to 1000 Mbps and needs no drivers, configuration or power.

Is it right for you?

• Suits joining two patch cables sold as Cat5 through Cat8 with standard RJ45 plugs, within the total channel limits.
• Suits Gigabit (1000 Mbps) networks; it is not a 10 Gbps part.
• For a critical or certified link, a single continuous cable is preferable to a join.

Key features

• Female-to-female 8P8C RJ45 connection for two terminated Ethernet leads.
• Rated up to 1000 Mbps.
• Internal metal shield around the socket path to help control EMI (electromagnetic interference) and crosstalk.
• Compact ABS housing, about 22 g.
• Passive: no drivers, configuration or power.

What else you need

• Two Ethernet cables with RJ45 plugs.

Before you buy

• Every extra connection adds contact points and can reduce margin on a marginal run.
• UGREEN refers to stable transmission within 50 m, but the real limit depends on both cable lengths, category, termination, environment and the active equipment.
• This model is rated up to 1000 Mbps. Do not expect 10 Gbps from it.
• PoE (Power over Ethernet) pass-through is not specified for this model, so confirm compatibility before using it in a powered Ethernet run.
• Ethernet cables, wall plate, keystone frame, switch and tester are not included.
