摘要： A method is provided for locating a fault arising in one or more optical amplifiers from among a plurality of optical amplifiers operating in saturation and located along an optical transmission path. The method begins by generating a COTDR trace representing a backscattered and/or reflected optical power level along the transmission path and comparing the COTDR trac e to a previously obtained reference COTDR trace to generate a difference trac e that represents a change in gain. The change in gain is assigned to at least one of the plurality of optical amplifiers based on the difference trace.

摘要： A method is provided for monitoring the status of an optical transmission path employed in a WDM transmission system and for transmitting service data over the optical transmission path. The method begins by transmitting the service data as an optical service signal carried at a first channel wavelength over the transmission path. The method continues by monitoring status information pertaining to the transmission path by receiving an optical monitoring signal in which the status information is embodied. The optical monitoring signal is carried at the first channel wavelength over the transmission path.

摘要： A branching unit is provided for interconnecting at least three undersea optical transmission cables. The branching unit includes first, second and third ports for receiving first, second and third undersea optical transmission cables, respectively. The first and second cables each include an electrical power conductor and a plurality of first optical fibers. The third cable is electrically unpowered and includes at least one drop optical fiber and at least one add optical fiber. An electrical power conductor segment is provided for electrically coupling the conductor in the first cable received in the first port to the conductor in the second cable received in the second port. A first optical fiber segment optically couples a first of the plurality of first optical fibers in one of the first or second cables to the drop optical fiber of the third cable. A second optical fiber segment optically couples a second of the plurality of first optical fibers in one of the first and second cables to the add optical fiber of the third cable. First and second optical amplifiers are located along the first and second optical fiber segments, respectively so that the first optical amplifier provides optical gain to traffic being dropped on the drop optical fiber of the third cable and the second optical amplifier provides optical gain to traffic being added on the add optical fiber of the third cable. At least one electrically conductive path is provided for supplying electrical energy from at least one of the electrical power conductors to each of the optical amplifiers.

The cable station includes submarine line terminal equipment (SLTE) for processing terrestrial traffic received from an external source, power feed equipment for supplying electrical power to active undersea components of the transmission system, an element management system for configuring and obtaining status information from the transmission system, and a cable termination box in which an undersea cable terminates. The SLTE includes terrestrial optical transmission equipment receiving the terrestrial traffic and generating optical signals in response thereto. The SLTE also includes an interface device providing signal conditioning to the optical signals received from the terrestrial optical transmission equipment so that the optical signals are suitable for transmission through the undersea optical transmission system.
