Procedure and device for measuring disturbing effects on glass fibre transmission lines |
摘要 |
The method involves using an optical light source (1), e.g. a laser (2), to provide two signals of different frequency, supplied to the optical fiber transmission path (7), with evaluation of the frequency difference between the signals received by a coherent receiver (8) at the opposite end of the transmission path. An Independent claim is also included for an optical transmission system. |
