STM-64 DATA MULTIPLEXER IN 10GB/S OPTICAL TRANSMISSION SYSTEM

摘要

The present invention relates to an STM-64 data multiplexing apparatus in a 10Gb / s optical transmission system that converts data used in an existing optical transmission network into a 10Gb / s data stream and provides it to a single optical path. A plurality of frame alignment means for aligning phases to eliminate the difference, section overhead processing means for performing an overhead insertion on data output signals of the plurality of frame alignment means, and overhead in the section overhead processing means A first multiplexing and dividing means for multiplexing and outputting the inserted signal, a second multiplexing and dividing means for multiplexing and outputting a signal of the first multiplexing means, and converting and outputting a result of the second multiplexing means into an optical signal Optical conversion means, first clock generation means for generating a primary clock based on a system clock, and the first clock generator Based on input of the first clock generated in the device consists of a second clock generating means for generating a second clock.
