纠误码在光纤通信系统中的应用

Application of Error-Correcting Code in Optical Fiber Communication System

介绍一种纠误码光纤通信系统原理框图,讨论了交错延迟十单位正反码自动纠误编码体制,指出这种纠误码光纤通信系统不但允许信息短期中断,而且可延长通信系统中继距离。作者已研制出低速交错延迟自动纠误设备,其编码与5B6B码型相比,可使系统可靠性显著提高,并减少字同步建立时间。

In this paper, the block diagram of error-correcting code optical fiber communication system is described. In the discussion,Automatic error-correcting icodes system of interleaving delay 10-bits positive-negative code is stressed, it s pointed out that optical fiber communication system with this error-correcting code not only permits information to be interrupted for a short time without lowering the communication quality, but also can extend the repeater spacing. The authors have developed a low-speed interleaving delay automatic errorcorrecting encoding equipment. Compared with line code 5B6B commonly-used internationally, this error-correcting code greatly improves reliabiling of the communication system and shortens set-up time of word synchronization.
