G.SHDSL 2 Ethernet Extender Kit

These kits include a pair of auto-rate Ethernet extenders, using a standard 2-/4- or 8-wire connection, which simplifies your life and provides 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 autosenses the data rate up to 45.6 Mbps at a distance of 1450 m (8-wire version) to provide reliable broadband connectivity with full-duplex symmetric rates, with lower speeds at longer distances of up to about (8.4 km). See distance charts under technical specifications.
