Westermo Unveils Robust, High-Speed Compact Ethernet Line Extender
Westermo Data Communications (News - Alert) a specialist in the design and manufacture of robust data communication devices for harsh environments has released a high-speed, compact device to serve the increasing data transfer demands over Ethernet in industrial applications.
The company supplies products based on proven commercial technology that provides the communication infrastructure for control and monitoring systems used in mission critical solutions where commercial grade products are not sufficiently resilient.
The new addition to the company’s series of Ethernet line extenders includes the DDW-142-485 which will form part of the Wolverine range. The device features the SHDSL technology which can establish a high-speed connection between Ethernet networks by leveraging existing copper cables. The solution is cost effective as it eliminates the need for new investments and the use of optic fiber.
Company officials explained that the DDW-142-485 is a fully managed device with Layer 2 switch functionality. It can help deploy Ethernet networks over distances of up to 15 km. The network can support data rates of up to 30.4 Mbps and can hence connect complex networks that are equipped to support numerous devices that require high bandwidth capacities.
The DDW-142-485 is robust enough to work in harsh environmental conditions such as in mission critical railway, road or utility applications. The device is rugged and compact and is suitable for working in extreme temperature conditions ranging from -40oC to +70oC. It can also perform well in cases where EMC (News - Alert) and vibration levels are high ensuring operational reliability and long life.
Also the Wolverine’s WeOS operating system enables the DDW-142-485 to function in a point-to-point, multi-drop or resilient ring network in addition to ensuring optimum security. Even if a link or hardware failure occurs, Westermo’s FRNT technology will be able to re-configure a large network.
The multicast addressing feature of the DDW-142-485 allows VPN pass-through for IPSec. It is compatible with protocols like Modbus/TCP and PROFINET I/O. The link fault forward (LFF) functionality sends the Ethernet link status over the SHDSL link between two units for easy monitoring.
Westermo supplied Ethernet switches for the vehicle monitoring system in the PATCO Speedline project in 2012. PATCO (Port Authority Transit Corporation) is a rapid transit rail system that operates in the Philadelphia area with a daily ridership of approximately 40,000 people.
