The optical amplifier also includes a plurality of pump radiation combiners, each pump radiation combiner coupling the radiation of a respective set of pump wavelengths of a respective source of the plurality of pump radiation sources and outputting the respective coupled radiation having coupled radiation profiles via a respective pump radiation combiner output. The optical amplifier also includes a coupler, such as a PxV coupler with P inputs and V out puts. The coupler is optically coupled to the outputs of the pump radiation combiners, receives the coupled radiation from the pump radiation combiners and outputs V pump radiation profiles to respective of V coupler outputs.

摘要： A collapsed ring fiber optic system includes a service path and a protection path provides at a shallow water portion of the fiber optic system, to deal with any fiber cuts that may occur at the shallow water portion without loss of main trunk bandwidth. The service and protection paths meet at a branch point, which is preferably located at a deep water portion of the fiber optic system. A passive combiner or 1x2 switch is provided at the branch unit, along with a detector and a processor, to determine whether any signals are being received from the service path, and if not, to reconfigure the system to accept signals from the protection path. At another shallow water portion of the fiber optic system, nearby where a destination is located, the signal provided on the optical path over the deep water portion is split into a service path and a protection path, to provide redundancy to deal with any fiber cuts that may occur. The fiber optic system may also be utilized for a land-based system, having high probability of fiber cut regions and low probability of fiber cut regions.

摘要： A system and method of providing a transmission span (100) that compensates for signal attenuation, dispersion, and nonlinearity of an optical signal communicated between two line units (102, 104) of a transmission link includes dividing the transmission span (100) into a plurality of fiber segments and selecting a particular fiber for each of the segments. The fiber selection and arrangement of fibers within the span (100) can be selected in accordance with the nonlinearity, dispersion conditions, and distributed gain conditions of the constituent fibers. In a three segment map, the first segment (110) can provide low non linearity, the third segment (130) can provide distributed gain, and the second segment (120) can compensate for the dispersion of the first and third segments (130). The span (100) can be used, e.g., for distributed Raman amplification. The span (100) can alternatively include a two segment map, a four segment map, or a map with additional segments.
