EN50155 hardened-grade Ethernet extenders ED3344 offers full-duplex up to 100Mbps communications link over existing coaxial cable. The built-in M12 Ethernet port can stand up to the continued vibrations, rain, and dust found in trains. The ED3344 provides wide operating temperature range, -40 to 75 degree Celsius, to handle any temperature fluctuations. It is the best long-distance Ethernet connectivity alternative when regular CAT-5 cable and fiber are not feasible to install yet data transmission bandwidth is a must. “We are proud to announce that our products meet all requiring criteria for the railway standards that will ensure product credibility to system integrators for their project-based equipment biddings,” Ben Chiang said, Product Manager at Etherwan.

To meet the harsh performance requirement of complex train communication systems, Etherwan indeed provides a higher level of reliability on railway applications. Etherwan’s EN50121-4 Ethernet switch, EX71000, emphasizes Gigabit Ethernet feature. The managed hardened-grade switch features 2 Gigabit ports that provide the real-time video and voice communications bandwidth required for security appliances. “Our mission is to support the trains, power distribution, signal control, and passenger service for outdoor railway applications,” Louis Chen, Product Manger, Ethernet Switch, at Etherwan. With the extended temperature range of -40 to 75 degree Celsius, it is designed to handle any temperature range along the transit. It comes with “α-ring” features that provide excellent redundancy with recovery time less than 15 milliseconds.
