4E1+100M PDH Fiber Optical Multiplexer

Brief Introduction IDM CH-120NET PDH multiplexer transmits 4E1 and two 100Mbps Ethernet networks over one or two fiber channels. The optical interface supports simple ALS function, code of E1 interface is HDB3 which meets all the international standards. It also has perfect monitoring and alarm function, high degree of integration, low power consumption and stable performance. Both desktop type and integrated type are available. 220VAC/-48VDC power supply alternative. It can be widely used in the mobile base stations, and DDN private network and etc. Features 1.Provide standard 4E1 transmission and two 100M Ethernet. 2.Ethernet ports support VLAN and flow control. 3.155Mbps speed rate of the optical interface and transmission distance more than 50km. 4.Support E1 loopback of COT (central office terminal) and RT (remote terminal), easy to test and manage. 5.Optical interfaces with 1+1 channel protection.(Either one fails, the other will back it up) 6.NMS interface optional (RS232/Ethernet).
