Black Box 10BASE-T/100BASE-TX Ethernet Extenders use vDSL 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 autosenses 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. The chassis has ventilation holes plus a fan to keep the extenders cool.
