Method for measuring the signal quality of an optical data signal |
摘要 |
A method for measuring the signal quality of an optical data signal is provided. To measure the signal quality, and in particular the signal-to-noise ratio of an optical data signal which has data-free time intervals, the signal strength of the transmitted optical data signal is measured during a data transmission. The signal strength of the noise signal is determined during the data-free time intervals. The signal-to-noise ratio is determined and used as a criterion for the signal quality of the optical data signal.
