Black Box Hardened Ethernet Extender Switch - short-haul modem - 10Mb LAN,

Simple plug-and-play installation.

Saves wiring costs by using voice-grade twisted-pair copper wire—even phone wire you already have installed.

Uses symmetrical vDSL for speeds of up to 30 Mbps.

Transparent to network protocols.

Eight speeds with easy-to-read speed indicator LEDs on top of the extender.

Auto MDI/MDI-X on the Ethernet ports.

Autosensing for Ethernet speed and duplex.

Hot swap extender without powering down.

A switch configures the extender for local (CO) or remote (CP) use.

The 10BASE-T/100BASE-TX Hardened Ethernet Extender uses vDSL to provide an easy, inexpensive way to extend the reach of your Ethernet network over ordinary voice-grade UTP copper wire. Use the Hardened Extender for harsh environments and extended temperature ranges. Because you use your existing copper infrastructure, you save on cabling costs.

Easy setup
Just plug a hardened extender into each end of your UTP wire and use simple DIP switches to set one unit as local (CO) and the other as remote (CP).

The extender is transparent to upper level protocols such as TCP/IP, and there's never any software to install. Plus, the RJ-45 port autosenses speed and duplex, and it features MDI/MDI-X, so your Ethernet is virtually foolproof!

Desktop or wallmount
You can use this compact extender as a desktop or a wallmount standalone unit.
