ABSTRACT:
A device for separating two light signals having different wavelengths transmitted in one and the same optical fiber, comprising an optical fiber terminating in two branched-off portions of fiber having in one case an extension of predetermined length, two photodetectors placed respectively at the output of said extension and of the other branched-off portion of fiber, delay means connected to the output of one of the photodetectors, differentiating means for receiving the signals generated by the delay means and the signals detected by the other photodetector, and an electronic processing circuit connected to the output of the differentiator.
