IDM-CH240NET PDH Optical Terminal

Overview:

The IDM-CH240NET series PDH optical terminal is an optical transmission device developed on the basis of VLSI (Very Large Scale Integration) technology, realizing transparent transmission of E1 circuits and 100M wire-speed Ethernet data channels with hybrid multiplexing and optical transmission; full-duplex/half-duplex auto-negotiation; the 8E1 optical terminal provides comprehensive local/remote alarm monitoring; featuring high integration, low power consumption, stable performance, and ease of use.

Product Features:

     Provides transparent transmission of 4/8/16 groups of E1 compliant with G.703 standard;
     Optical terminal provides 155Mbps optical interface transmission rate;
     Optional dual power supply for the optical terminal;
     Supports E1 tributary loopback function for easy line testing and management;
     Optional dual optical port redundancy, supporting forced switching or automatic protection switching;
     Optical terminal provides 2 groups of shared wire-speed 100M Ethernet interfaces with VLAN partitioning capability.
