In an ideal digital transmission system, the pulse stream should consist of a sequence of points equally spaced in time by a quantity T, the inverse of the pulse transmission rate. In practice, the points of actual sequence are randomly deviated from their desired positions. Such timing deviations called timing jitter is usually classified into two main categories; systematic jitter and nonsystematic jitter. The former depends on the transmission signal, while the latter is produced by noise source. It has been verified that systematic jitter accumulation exceed nonsystematic one's. Nowadays, optical systems use optical amplifiers to enhance the transmission signal and recover its timing. Therefore, the influence of clock recovery circuit (CRC) inaccuracies is very significant in optical communication systems since a small timing error may influence the system performance a lot. In this paper, we proposed a new CRC model that can be more powerful to analyze the jitter performance and get the better optical communication results.
