This kit includes a pair of auto-rate Ethernet extenders, using a standard 2-wire connection, which simplifies your life and provides a cost-effective network extension by enabling you to make the most of your pre-existing twisted-pair infrastructure.

You’ll be able to connect remote LANs across distances and at speeds previously unheard of. An auto-rate feature ensures that you achieve the highest possible speed on each connection.

It’s easy to use, too. Plug-and-play means that you’ll be up and running in seconds, and the built-in MDI-X works with either straight-through or crossover cables.

The pair auto senses the data rate up to 45.6 Mbps at a distance of 4750 feet (1450 m) to provide reliable broadband connectivity with full-duplex symmetric rates, with lower speeds at longer distances of up to about 5.2 miles (8.3 km).

Ethernet Extender Industrial Coax. Extends one port 10/100Mbps Ethernet RJ45 over Coax cable interface, BNC. Used in pairs for point to point Ethernet extension. Typical applications include Enterprise LAN extension, campus LAN expansion. 10BASE-T/100BASE-TX Ethernet Extenders use vDSL technology to provide an easy, inexpensive way to extend the reach of your Ethernet network over ordinary voice-grade copper wire or coax cable.

Just plug an extender into each end of your copper wire and use simple DIP switches to set one unit as local (CO) and the other as remote (CP) – there’s never any software to install. Plus, the RJ-45 port auto senses speed and duplex and features MDI/MDI-X for easy cabling For larger installations, you can mount the extenders in a convenient 16-slot rackmount chassis (LB300A-RACK).
