Abstract

It has been developed a signals optical generator for telecom-munication equipments, comprising at least a single-frequency active optical fibre laser as optical signals source at an emission wave-length, at least an active optical fibre optical amplifier operative-ly connected to said laser and supply means of pumping optical power at pumping wavelength; within the generator said pumping optical power supply means are operatively connected to at least one of said active fibres of said laser and amplifier and transfer-means of said pumping optical power are operatively connected to said active fibres of said laser and amplifier. in order to transfer not absorbed optical power at the pumping wavelength from one of said active fibres to the other of said active fibres.
