摘要： An optical device that measures and dynamically compensates power loss variations in an optical fiber based on supervisory signals. An injector injects supervisory signals having a predefined optical power downstream of the fiber entry end and a detector extracts the supervisory signals at the exit end of the fiber to detect their optical power. Based on the detected optical power and the predefined optical power, the optical power loss of the supervisory signals in the fiber is determined. The optical power loss and the nominal power loss in the fiber are compared to determine a variation in the power loss in the optical fiber. A controller coupled to the detector and to the exit end of the fiber modifies the power of primary signals delivered by the exit end of the fiber as a function of the detected variation in power loss.

摘要： The invention relates to a method of providing protected transmission between two nodes (1, 2) of a wavelength-division multiplexed network. The invention proposes to have loss of signal over the main line (3) detected by a node, and then to interrupt transmission of data over the main line by said node. By interrupting transmission, it is thus possible to force loss of signal on the other node: the other node then switches its transmission of protected data over to the backup line (4). Interrupting the transmission of data can be achieved by switching off the laser of said node. The invention also describes a method of testing with a view to re-using the main line (3). The invention provides means for switching the protected data over to the backup path that are particularly simple in terms of protocol.
