ABSTRACT:
An optical transmission system comprises amplified forward and return paths between a local station and a remote station. Each amplifier of the forward path has an attenuated loopback coupling its output to the return path. Frequency modulated supervisory signals generated at the local station are returned via the loopbacks. These signals are analysed e.g. by Fourier analysis to obtain a measure of the performance of each amplifier. The system may also be employed for the location of fiber breaks.
