DDW-220 Ethernet Extenders
The DDW-220 can be used to extend Ethernet networks over existing copper cables in point-to-point or line sharing applications. Point-to-point transmission distances of up to 10 km can be achieved with data-rates of 5.7 Mbit/s possible over shorter distances on a single copper pair. The built-in 4 port Ethernet switch makes the DDW-220 the only necessary component required to create a small network. Total galvanic isolation between all interfaces, extended type approvals and rugged mechanical design as well as extensive over-voltage protection and line interface voltage suppression makes the DDW-220 the best solution in harsh industrial environments.
