Abstract

A system for physical layer supervision in optical networks based on tuneable OTDR, an hybrid optical switch and a FOCS. The system comprising: - a light source arranged to inject a monitoring light signal using a plurality of different wavelengths together with at least one data light signal at an input of an optical network or a dark fibre to circulate there through; - a plurality of optical filters provided at different points of said optical network in case of in-line PON monitoring to receive said monitoring light signal and filtering at least part thereof, in the form of respective reflected light signals; - light detecting means arranged to receive said respective reflected light signals from said optical network or said dark fibre; and - analysis means connected to said light detecting means to analyse said received reflected light signals to perform a physical layer monitoring of the optical network; the system further comprises: - a fibre optic cross-connection system, or FOCS, between said light source and said optical network or said dark fibre and comprising at least one hybrid optical switch to deliver said light signal to a desired optical network or to a dark fibre, depending on said plurality of different wavelengths. The hybrid optical switch, for fibre switching a light source injecting a monitoring light signal using a plurality of different wavelengths comprising at least one passive optical wavelength multiplexer-demultiplexer to deliver said light signal to another of said hybrid optical switch or to a desired optical network or to a dark fibre, depending on said plurality of different wavelengths. The fibre optic cross connection system, or FOCS, comprising at least one hybrid optical switch to deliver a light signal to at least one desired optical network or dark fibre, depending on a plurality of different wavelengths.
