Extend Ethernet at high speeds over an existing copper wire with the Black Box® brand Multi-Rate Ethernet Extender.

Using discrete multi-tone (DMT) line modulation, the extender provides high-speed Ethernet services between LANs or other network-enabled devices over a single twisted-pair cable. You receive two boxes: One is configured as the local line driver, the other as the remote line driver.

This variable-rate standalone line driver enables you to select various asymmetrical and symmetrical rates to satisfy a broad range of applications. Typical uses in symmetrical mode include videoconferencing, interactive video, and telecommuting. The asymmetrical mode is used primarily for delivering Internet service.

The extender operates over the twisted-pair phone cable you already have installed, so you don't have to re-cable with CAT5e or fiber cable.

The driver is easy to install, too. Simply plug and play, and use the handy DIP switches to select mode and speed.

The extender must be used in pairs and requires one unit for the local site and one unit for the remote site for proper operation. Both units are included.

Ethernet Extender Kit 2 Port. Extends 2 ports 10/100Mbps Ethernet RJ45 over copper or CATx line interface, RJ45. The kit includes 2 extenders for near-end (local) far-end (remote) deployment. Typical applications include Enterprise LAN extension, campus LAN expansion. 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. These 2 port 10BASE-T/100BASE-TX Ethernet Extenders use ADSL technology to provide an easy, inexpensive way to extend the reach of your Ethernet network over ordinary voice-grade copper wire. Devices include internal 120240VAC power supplies.
