## Long description

The StarTech.com 1-Port Gigabit Network Isolator is a compact in-line RJ45 Ethernet coupler that provides 4kV galvanic isolation to protect network devices from harmful power surges and stray electrical currents. TAA-compliant and supporting 10/100/1000 Mbit/s, it separates conductive connections between devices connected by an Ethernet cable while remaining transparent to network traffic and OS independent.
Advantages
This network isolator is bus-powered and requires no external power, drivers, or software, offering true plug-and-play operation. With two RJ45 ports it functions as a simple coupler for Cat5/Cat6 cables, provides full transparency on the network without routing or altering traffic, and helps prevent ground loops in audio and video setups. The device meets safety and EMC standards (ETL listed to IEC 62368-1 and CE: EN55032/EN55035) and supports reliable performance in industrial and lab environments.
Suitable for
Protecting networked audio/video equipment from ground loops and surges
Industrial and laboratory network infrastructure requiring galvanic isolation
DIN-rail or adhesive-mounted installations in control cabinets and enclosures
Temporary network maintenance, testing, or equipment upgrades where isolation is needed

How to use
Install the isolator inline by connecting an Ethernet cable from the source device to one RJ45 port and a cable from the other RJ45 port to the destination device or network. No configuration, drivers, or grounding wire are required. For fixed installations, attach the isolator using the included DIN rail kit or an appropriate adhesive on a clean surface. Ensure Cat5 or Cat6 cables are fully seated in the RJ45 connectors to maintain reliable connectivity.
Usage recommendations
Use the isolator in environments where electrical separation is required to prevent ground loops, surges, or stray currents. Verify compatibility with your network topology and avoid inserting the device in links requiring Power over Ethernet (PoE) unless the network design accounts for isolation limitations.
