PDH Optical Multiplexer
Description:
PDH Optical Multiplexer is a self-developed small-capacity transmission device. We adopt large scale integrated circuit design; multiplex 1-16 channels' E1 and 100M Ethernet signal which compliance with ITU-T standard for transmission over fiber. This series of products as a mature technology products with excellent performance, internal hardware and software are modular structure. We adopt veneer construction in circuit, large FPGA circuit in hardware, integrate encoder and digital smooth lock to a body, so that the indicators much better than ITU-T recommendations. Especially suitable for those places that request small communication capacity, high reliability and complete interface type. It has been widely used in private communications network such as telecommunications, electricity, railways, military, banks, etc.
