Abstract

In the paper the problem of low-jitter clock recovery in the fiber optic transmission is discussed. The basic receiver structure is presented and the the amplitude noise to jitter conversion phenomenon is carefully analysed. The special attention is paid to the low-pass filtering of the received signal. The contradiction between low-BER and low-jitter oriented filtering its pointed out. To verify the theoretical analysis results the hardware experiment and the measurement results are also presented. Some practical conclusions are drawn and among others the use of excess bandwidth of the fiber optic transmission channel is proposed as the basic way of the received signal jitter reduction. In the final part of the paper the new concept of the low-jitter and low-BER fiber optic receiver structure is presented.
