    摘要： In a fiber optic assembly that is sealed within an enclosure and that has a plurality of optical transmission paths available to transmit input signals through the assembly, a separate link is provided for each transmission path. Each of the separate links has a first end that is located external to the sealed enclosure and a second end that is located within the enclosure and adjacent to the link's associated transmission path. The link is capable of transmitting energy from an energy source coupled to the link at the first end through the link to the second end. The energy is received at the second end of the link, where the second end's proximity to its associated optical transmission path allows the energy to act on the transmission path to render the path inoperable for transmitting an input signal along the path and through the assembly. As such, the fiber optic assembly is configured to permit selected input signals to be transmitted through the fiber optic assembly to a particular destination based upon the requirements of the communication system into which it is integrated.

    摘要： A lightwave communication system is provided that includes first and second optical transmitters/receivers remotely located with respect to one another. First and second optical transmission paths couple the first transmitter/receiver to the second transmitter/receiver for bidirectionally transmitting optical information therebetween. First and second doped optical fibers are respectively disposed in the first and second optical transmission paths. Optical pump energy is supplied by first and second optical pump sources. The first optical pump source generates Raman gain in the first transmission path and the second optical pump source generates Raman gain in the second transmission path. A first optical coupler is provided for optically coupling pump energy from the first pump source to the second-doped optical fiber and a second optical coupler is provided for optically coupling pump energy from the second pump source to the first doped optical fiber.

    摘要： A path couples a pair of optical fibers in an optical transmission system. The transmission system includes a plurality of optical amplifiers placed along the transmission line. Associated with these optical amplifiers are optical isolators that limit the flow of optical energy to a single direction. The path allows reflected or scattered light from one optical fiber after the optical isolator to be returned via the other optical fiber. This enables an OTDR device to obtain measurement information along the entire length of the fibers between optical isolators.

    摘要： A high-powered optical pump includes at least two sub-pumps. Each sub-pump generates light at different wavelengths. The outputs of the sub-pumps are coupled to a remote pump fiber. The resulting light transmitted on the remote pump fiber results in a lower Raman gain and Raman noise spectral peak than that generated by existing single wavelength high-powered optical pumps at the same power level. Therefore, increased power can be transmitted on the remote pump fiber in contrast to a single wavelength pump. Additionally, the total gain spectrum available for the amplification of signals is increased.
