STM-64 signal demultiplexer in 10Gb / s optical transmission system

摘要

The present invention relates to an STM-64 signal demultiplexer in a 10 Gb / s optical transmission system that receives STM-64 (10 Gb / s) data in a 10 Gb / s optical transmission system and transmits 128 data at 78 Mb / A first demultiplexer for demultiplexing the output data of the demultiplexer into first and second demultiplexed signals; a demultiplexer for demultiplexing the output data of the first demultiplexer into first and second demultiplexed signals; Section overhead processing means for processing the STM-64 section overhead in the output data of the second demultiplexing means; and a multiplexing means for multiplexing the output data of the section overhead processing means A multiplexing unit for receiving the data output from the buffer means and processing STM-1, STM-4, and STM-16 signals; STM-4, and STM-16 multiplexers, which are used in existing optical transmission networks, and offer advantages such as device cost, heat treatment problem, and power consumption due to 30% And multiplexing STM-64 multiplexing of these signals to perform demultiplexing for signal matching, it can be extended to 10 Gb / s in one optical transmission line.
