IDM GTD442 Dual Gigabit telephone transmitter
IDM GTD442 Dual Gigabit telephone transmitter
一 Product Overview
IDM GTD442 is a fiber access device with a variety of configurations, it can provide Ethernet, telephone, serial port optical multiplexing, and IDM GP2000 series optical interface device interoperability. IDM GTD442’S fiber interface rate is 2.5G, can provide 2 wire speed 1000M Ethernet ports, each line speed 1000M interface has a electrical GE and an optical GX; also can provide 18 E1 bandwidth of transmission channel. IDM GTD442 in the transmission line interface provides up to two groups of optical fiber interface, constitute a backup, or light chain network, ring network etc.. In the user interface, can provide 4 groups Ethernet ports, 4 channels phone, 2 channel RS485 or 1 RS422 channel is provided. The Ethernet interface can be configured as a physical isolation or VLAN isolation mode. Can be widely used in public security, electricity, railways, mines and other network and mobile, Unicom, telecom and other public areas.
