Abstract
A system is disclosed for monitoring repeaters of an installation for transmission of signals via optical conductors in which each repeater includes an optical amplifier for amplifying the signals transmitted by the optical conductors. A remote monitoring signal is transmitted from a main or monitoring center to each repeater. The system includes, at the main center, a remote monitoring signal transmitter having a wide spectrum of optical wavelengths, preferably at least as wide as the wanted spectrum of wavelengths of the optical signals transmitted on the conductors. In this way the wanted signal is virtually undisturbed by the remote monitoring signal.
