摘要： Methods and apparatuses for enabling supervision of fibres (208) in an optical communication network, where a Central Office (200) provides data signals to a Remote Node (204) for distribution to Optical Network Terminals, ONTs (206). The Central Office generates and sends test signals of different monitoring wavelengths associated to predefined groups of said ONTs, to the Remote Node. The Remote Node routes each test signal to a corresponding associated group of ONTs (206) according to the wavelength of the test signal. When receiving a back-scattered and back-reflected test signal caused by a faulty optical fibre, the Central Office is able to identify the faulty optical fibre based on the wavelength of the back-scattered and back-reflected signal.
