4E1+1Gigabit PDH Multiplexer

Delivery Time:3-5 business days IDM-120GNET optical transmission equipment can transmit and two 1000Mbps Ethernet networks simultaneously. The optical interface supports simple ALS function, the code of E1 interface is HDB3 which meets all the international standards. Provide 2 Ethernet networks with physical isolation sharing 1000M bandwidth.

It also has perfect monitoring and alarm function, high degree of integration, low power consumption, stable performance and 220VAC/-48VDC power supply alternative. It can be widely used in the mobile base stations,remote module of the switch and DDN private network and etc. 1.

Features of 4E1+1Gigabit PDH Multiplexer Provide 2 Ethernet networks with physical isolation sharing 1000M bandwidth. Provide standard 4E1 transmission Support E1 loopback of COT(central office terminal) and RT(remote terminal), easy to test and manage.
