Paper Abstract

In the optical fiber digital transmission system for long haul trunk, line code is very important for quality of transmitted information. Our country has a vast territory. Not only long haul trunk with good quality is needed, but enough channels are also needed for local section communication along the line. For this purpose, Wuhan Research Institute of Posts and Telecommunications, China, has put forward line code 8B1H adoptable in the local section along the long haul trunk to insert and drop channels. But because code H and C are inserted alternatively, the synchronization of codewords, in service error rate monitoring, and the number of consecutive identical code are affected. A new kind of line code nBCH is presented here on the basis of studying to code 8B1H.
