Optical Transceiver/WDM Gigabit Ethernet/Fiber сhannel (1250 Mbps)

A media converter is used as a converter that converts one signal transmission medium into another. The data transmission medium means optical and copper cable. The scope of application – FastEthernet and GigabitEthernet protocols, STM-1 and STM-4. Media converters are characterized by a number of parameters, by setting that you can choose the optimal network equipment for solving a specific task. The possibility to control the device; Installation location; Properties of the optical receiver-transmitter; Supported transfer rate.
