Abstract�� The error code performance is one of the most important transmission performances for optical fiber digital transmission system. And for synchronous digital hierarchy(SDH), the error block performance is usually used to describe error code performance. The error block performance under the inference of background noise which is usually described by Poisson distribution and impulse disturbing which is usually described by Neyman-A contagious distribution were discussed for SDH system. The general relationship of error block ratio on Poisson distribution and Neyman-A contagious distribution was derived.
Keywords�� impulse   interference   noise   error code rate   Poisson distribution   Neyman-A contagious distribution
