Abstract
A method of measuring the error rate of an optical transmission system transmitting a signal bydetecting the signal, andasynchronously 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.The eye diagram of the signal,the error rate of the signal and the bit time of the signal are then computed.
