4E1 PDH Multiplexer
The 4E1 PDH Multiplexer can multiplex 4E1 and 1 optional port Ethernet (10/100Mbps) signals in one fiber to transmit. It is suitable for low capacity, point-to-point application of remote transmission. The circuit part of the equipment is fully digitized. The whole equipment is reliable, stable, easy to install and maintain. It has good temperature and voltage characteristics, complete alarm functions, one RS232 asynchronous interface and remote loop back functions(from software). At the same time, it can be managed by management software.
