1+1 PDH Optical Multiplexer

1+1 Fiber port PDH Optical Multiplexer provides function of ordering 4E1/8E1/16E1 to loop return from the remote end, fiber self-loop at local end; and provides a group service telephone interface (to select). The main difference between these two products is the second one has one spare fiber port. It is suitable for low capacity, point to point application of remote transmission. The equipment is reliable, stable, easy to install and maintain… [Details]
