PDH Multiplexer(4, 8, 16E1+100Mb Ethernet+Rs232+SNMP+OW)

详情

Overview: CL-FOM***0 4E1***0Mb Ethernet PDH (Plesiochronous Digital Hierarchy) which was used in exchanger for long distance transmission, and platform of mobile telecommunication, pager transmission station ect., which was used in mini-medium column and point to point products with fiber supporting, the equipment adopted powerful function and expert digital repeating-connection chips which integrated all digital and logical function in the equipment so that improved the performance and reduced the cost of products, the completed-equipment with good performance, stable operation, low loss, strong integration capacity, small bulk, easy installation and maintenance. Standalone and Rack mount module are both available. Feature: 1.
