Abstract

The invention discloses a modularized network type PDH optical transceiver comprising an optical signal receiving end, an optical / electric converter, an electric signal demultiplexer, a D / A converter, an amplifilter and a user receiving end. An output end of the optical signal receiving end is connected with an input end of the optical / electric converter. An output end of the optical / electric converter is connected with an input end of the electric signal demultiplexer. An output end of the electric signal demultiplexer is connected with an input end of the D / A converter. An output end of the D / A converter is connected with an input end of the amplifier. An output end of the amplifier is connected with the user receiving end. An ADPLL phase-locked loop circuit is also connected between the amplifier and the user receiving end. The modularized network type PDH optical transceiver of the invention can effectively reduce signal jittering at an E1 interface.

Description

technical field [0001] The invention relates to a PDH optical transceiver, in particular to a modularized network PDH optical transceiver. Background technique [0002] In the telecommunications network, PDH optical transceivers are mostly used. This PDH optical transceiver series has good adaptability to traditional point-to-point communication. Its unified bit rate and unified interface standard provide the possibility for interconnection between devices from different manufacturers. With the rapid development of digital communication, in order to meet the needs of modern telecommunication business development and modern telecommunication network management, PDH optical transceivers must be continuously improved. The most intuitive feeling that can be given to customers is the stability of the network. There are many reasons for the jitter of the E1 interface provided by the PDH optical transceiver to the user. The jitter of the E1 port signal will bring inconvenience ...
