November 26, 2002--Available in a temperature-hardened version for harsh environments, the new optical Ethernet switch from
TC Communications (Irvine, CA) supports distances up to 100 km.
The TC3705 Ethernet switch provides four 10/100-Mbit/sec auto-sensing UTP ports and one fiber-optic 100Base-FX port. It is available for multimode or singlemode (1300/1550 nm) and supports full or half-duplex operation.
The standard version supports temperature ranges from -10°C to 50°C; the "Hi-Temp" version supports ranges from -20°C to 70°C; and, the "Hardened" version supports ranges from -40°C to 80°C and exceeds all pertinent environmental and temperature specifications for Utility and Traffic Control environments.
Because the TC3705 Ethernet switch is based on the latest switching technology it eliminates most congestion problems, especially those related to the Ethernet CSMA/CD protocol. As a result, it creates efficient sub-divided switched LANs and provides full and transparent bandwidth for each segment.
