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 in a first network node for determining a latency of a transmission link between the first network node and a second network node in a communications network. The first network node transmits (1101) an electromagnetic signal to the second network node over the transmission link as a first Frequency-Division Multiplexed, FDM, signal comprised in a first electromagnetic carrier also comprising payload data. The first network node receives (1102) the electromagnetic signal from the second network node over the transmission link, wherein the electromagnetic signal has been transmitted from the second network node as a second FDM signal comprised in a second electromagnetic carrier also comprising payload data. The first network node determines (1103) the latency of the transmission link based on a phase difference between the transmitted electromagnetic signal and the received electromagnetic signal.
