Industrial GSHDSL modem
S20 SHDSL Semaphore

The Semaphore S20 SHDSL Modem extends communication speed and reach without the additional investment of installing new communications media. An alternative to wireless technology, the S20 SHDSL Modem’s unique repeater capability enables communications over existing copper wire networks spanning up to hundreds of kilometers. The modem is ideal for railway, pipeline, utility and power transmission applications that presently employ a copper wire communications network.

Semaphore’s S20 SHDSL Modem extends dual Ethernets at high speeds over copper wire pairs to allow for the connection of multiple devices using standard IP protocols. Unlike most products, which inherently limit transmission distance, our S20 SHDSL Modem features a repeater mode which provides excellent reach capabilities.
