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.

摘要： A method performed by a transceiver for use in a fibre network for sending and/or receiving signals on the fibre network. The transceiver comprises an SCM device; a laser diode; a Red-Blue Filter, RBF, having a red, a blue and a common channel; a PD; and a Sub-Carrier Demultiplexing, SCDM device. The SCM device receives electromagnetic signals on at least two input ports, multiplexes the electromagnetic signals into an electromagnetic signal and outputs the signal to the laser diode. The laser diode receives the signal, converts the signal to optical signals comprising a plurality of sub-carriers of different frequencies distributed in frequency around a main optical carrier, and outputs the sub-carriers to the red channel of the RBF. The RBF receives the subcarriers, and outputs the subcarriers to the fibre network via the common channel. The RBF also receives subcarriers on the common channel and filters out blue frequencies of the subcarriers and outputs the subcarriers having blue frequencies to the photo diode. The photodiode receives the subcarriers having blue wavelengths from the RBF, converts the subcarriers into an electromagnetic signal and outputs the electromagnetic signal to the SCDM device; and the SCDM device demultiplexes the electromagnetic signal into at least two electromagnetic signals and outputs the at least two electromagnetic signals.
