Abstract
A method in a network node for determining information associated with an optical fiber in a communications network. The optical fiber is connected to an optical transceiver unit. The network node configures the optical transceiver unit to transmit at least one first optical signal via the optical fiber, wherein the at least one first optical signal is an optical pulse train defined by a determined period. The network node then obtains information associated with at least one second optical signal received by the optical transceiver unit via the optical fiber in response to the transmitted at least one first optical signal. Thus, the network node may determine information associated with the optical fiber based on the obtained information. Also, an optical transceiver unit for enabling a determination of information associated with an optical fiber in a communications network and methods therein.
