The JetCon 3401G, industrial Gigabit Ethernet media converter, is equipped with a rugged aluminum alloy case with IP-31 grade ingress protection against damage by solid objects or dust. With excellent heat dissipation characteristics, the JetCon 3401G is capable of performing better than ordinary Gigabit Ethernet media converters which are enclosed by steel metal with various heat dissipation holes. Unlike those with a single power input, the real time redundant power backup on JetCon 3401G leads to the functionality of a real Industrial Gigabit Ethernet Media Converter with the non-stop transmission.
