Description

4E1 PDH Fiber Optical Multiplexer

Introduce

PDH-4 Compact Optical multiplexer is a low cost and high performance optical line transmission equipment, which combines four ITU-T G.703 compliant standard electrical E1, 2.048Mbps signals into an optical data stream for transport over fiber optic cables. Several transmitter options for different cable types and wave-lengths are available. This optical line equipment is developed for transmission in access networks, corporate networks, dedicated networks for railway and power companies etc.
