ABSTRACT:
A method for determining a quality indication, such as a bit error rate or a signal to noise ratio, of a photonic signal is described. The photonic signal is sampled, and then an estimated quality indication, such as the bit error rate, is calculated utilizing statisical analysis of the sampled photonic signal.
