Method of measuring the error rate of an optical transmission system and apparatus for implementing the method

Abstract

The present invention relates to a method of measuring the error rate of an optical transmission system transmitting a signal, said method comprising the following operations: detecting the signal, asynchronously sampling the signal at a frequency independent of the bit rate of the signal to obtain K samples of the signal at respective times t1 to tK where K is an integer greater than or equal to 2, computing the eye diagram of the signal, and computing the error rate of the signal. After sampling the signal, the method further comprises an operation of computing the bit time of the signal.
