ABSTRACT:
A performance evaluation analysis for optical transmission systems is disclosed. A reference eye mask is defined for a transmitter and for a reference optical transmission link. The quality of the transmission for a live path is determined by applying the reference eye mask on the eye diagram of the electrical signal recovered at a point of measurement with a distortion measurement unit. The point of measurement could be established at a receiver optical connection plane, for measuring the optical transmission link and transmitter penalty, or could be at the optical connection plane of a transmitter, for measuring the performance of the transmitter. The optical path may include optical amplifiers, dispersion compensating modules, active and passive components.
