远距离测试发控系统中数字光纤通信系统的接口设计及实现

Design and Realization of the Interface of Digital Optical Fibre Communication System for Long Pistance Test Lunch and Control Systems

远距离分布式计算机网络测试发控系统是当今国际宇航事业发展的方向。数据通信系统能否畅通、准确、实时、可靠是实现远距离测试发控的关键。本文列举了光纤通信的优点，分析了通信中常用纠错编码的优劣，提出一种既符合测试发控系统的特点又适合光纤通信要求的新的纠错编码方案，并设计出以该纠错编码为核心的数字光纤通信接口，满足了一个特定的远距离测试发控系统对数字通信的要求。

The long distance distributed computer network test, launch and control system is currently, developing trend of internotional aerospace undertaking. An unblocked,accurate,real-time and highly reliable data communication system is the key for implementing long distance test, launch and control. This paper lises the advantages of opticalfibre conmmunication,analyses the advantages and disadvantages of error correcting code used in most comuunication system and proposes a new design scheme for error correcting code, which both accords with the characteristics of test,launch and control system and satisfies the requirements of opticalfibre communication. An interfacefor digital opticalfibre communication system with the error correting code presented in thiS paper as core has been designed,which satisfies the requirements of a particular system.
