摘要： A land-based cable station is provided for interfacing with first and second undersea transmission segments of an undersea optical transmission system. The cable station includes optical transmission terminal equipment for receiving and transmitting optical signals that undergo opto-electric conversion therein. A first interface device is operably coupled to the terminal equipment for bidirectionally communicating optical signals between the terminal equipment and the first undersea transmission segment and for providing signal conditioning to the optical signals received from the terminal equipment so that the optical signals are suitable for transmission through the first undersea transmission segment. A second interface device is operably coupled to the terminal equipment for bidirectionally communicating optical signals between the terminal equipment and the second undersea transmission segment and for providing signal conditioning to the optical signals received from the terminal equipment so that the optical signals are suitable for transmission through the second undersea transmission segment. At least one first bypass optical transmission path is provided for selectively coupling refiectometry probe signals and backscattered and reflected signals located at a prescribed wavelength from the first interface device to the second interface device. At least one second bypass optical transmission path is provided for selectively coupling reflectometry probe signals and backscattered and reflected signals located at a prescribed wavelength from the second interface device to the first interface. The first interface device includes a first loopback path for selectively coupling the backscattered and reflected optical signals from a first optical transmission path located therein that receives the reflectometry probe signals from the second bypass path to a second optical transmission path located therein that couples the reflectometry probe signals to the first bypass path. The second interface device includes a second loopback path for selectively coupling the backscattered and reflected optical signals from a second optical transmission path located therein that receives the reflectometry probe signals from the first bypass path and a first optical transmission path located therein that receives the reflectometry probe signals from the second bypass path.

摘要： A method and apparatus is provided for obtaining status information concerning an optical transmission path. The method begins by generating a COTDR probe signal having a prescribed wavelength and transmitting optical traffic signals and the COTDR probe signal over an optical transmission path (306) having a length corresponding to those used in regional undersea market applications. The prescribed wavelength of the COTDR probe signal is separated from wavelengths at which the optical traffic signals are located by a distance at least equal to a predetermined guard band. A backscattered and/or reflected portion of the COTDR probe signal in which status information concerning the optical path is embodied is received over the optical path. The backscattered and/or reflected portion of the COTDR probe signal is detected to obtain the status information.
