UGREEN 30837 RJ45 Inline Coupler with Lightning Surge Protection, Gigabit

Overview

The UGREEN 30837 is a small inline RJ45 coupler with built-in lightning and surge protection, for network cables that run outdoors or between buildings, such as links to gate cameras, rooftop access points or outhouses. It joins two cables with RJ45 plugs and adds a protective stage on the line, so a nearby strike is less likely to send a damaging surge into routers, switches and PCs.

Is it right for you?

• Suits exposed runs: a gate camera, a rooftop access point, an outbuilding or any cable that leaves the building.
• Suits 1 Gbps links on Cat 5e, Cat 6 and Cat 7 cables; it is not intended for 10 Gbps networks.
• It needs a proper earth in the installation to protect anything, so it suits a job done by an installer or electrician who follows local electrical practice.

Key features

• Built-in lightning and surge protection on the network line.
• Signal transmission rated at 1 Gbps.
• Works with Cat 7, Cat 6 and Cat 5e cables with RJ45 plugs.
• 24K gold-plated copper pins for corrosion-resistant contact.
• PVC housing with snap-in retaining clips; about 5 x 3.3 x 3.3 cm and 20 g.

What else you need

• Network cables with RJ45 plugs on both sides.
• A proper earth connection in the installation, following local electrical practice.
• It works with network cards, routers, switches, hubs and other LAN equipment.

Installation

An installer or electrician should fit it where the exposed cable enters the building and connect the earth in line with local electrical practice. Without a proper earth the protection does not work.

Before you buy

• A surge protector reduces risk but cannot guarantee protection from a direct strike.
• Protection depends on a proper earth.
• Plan link speed on the 1 Gbps rating; it is not intended for 10 Gbps networks.
