SDH传输设备误码的来源及解决办法

The Sources of Error-code of SDH Transmission Equipment and Solutions

SDH传输设备的误码是由均匀误码、随机误码和突发误码组成的。均匀误码来源于内部信号的同步关系,随机误码来源于设备内部的电磁辐射干扰,突发误码来源于设备的电源或时钟条件被破坏。各种误码都有随环境条件恶化而扩大的趋势。误码的来源不同,解决的方法也不相同。调整信号时序,改善电源和时钟条件,降低幅射发射,是解决传输设备误码问题的基本方法。

The error-code of transmission equipment (SDH) is consisted of equality error-code., random error-code and burst error-code. The equality error-code is caused from synchronization relations of inside signals. The random error-code is caused from disturb of inside electromagnetism emission. The burst error-code is caused from broken-out for correct power or correct clock. All error-code was extended when environment was worsen. The solutions was unlikeness because the sources of error-code was different. it is the basis method of get over error-code to adjust the delay time, improve power and clock and reduce the electromagnetism emission.
