Ethernet line extenders
04 December 2008
Westermo Data Communications has enhanced its’ “Wolverine” range of industrial Ethernet line extenders by adding a high speed unit for simple point-to-point applications and achieving ATEX approval for three existing devices.
The Wolverine DDW-220, 221 and 222 high speed Ethernet line extenders have been ATEX approved and can be fitted in Zone 2.
Ethernet line extenders
The series uses SHDSL technology to establish a high-speed remote connection between two Ethernet networks using any existing twisted pair copper cables.
The high speed DDW-120 Ethernet Line Extender has been launched, capable of extending Ethernet networks over copper cables. The DDW-120 is specifically for point-to-point applications or as a start or termination unit together with the DDW-220/221/222 in daisy-chain applications.
At shorter ranges the data rate will be as high as 5.7 Mbit/s in both directions. Transmission distances of up to 10 km can be achieved at lower data rates. The units will auto-negotiate the transmission speed but can also be forced to choose a slower or faster data rate.
As with other products in the Wolverine series the DDW-120 can operate in a wide temperature range (–25 to +70°C) and total galvanic isolation and transient protection of the electronics makes it suitable for a broad range of applications.
