摘要： A method of communicating an optical signal includes generating an optical signal at a bit rate of at least 2.5 Gb/s. The optical signal including at least thirty optical channels. In one particular embodiment, at least some of the thirty optical channels reside within a 1567-1620 nanometer wavelength range. The method also includes receiving the optical signal at a ROPA that includes a rare-earth doped optical fiber. In addition, the method includes introducing a pump signal to a communication span of the unrepeatered optical communication system. The pump signal operable to amplify the optical signal by Raman amplification within the communication span and including at least one pump signal wavelength operable to excite the rare-earth doped fiber.

摘要： An optical communication system includes a transmission fiber that is operable to receive at least one optical signal and at least one pump signal. The optical signal includes one or more optical signal wavelengths and a power level at approximately a minimum threshold power level. The pump signal co-propagates with at least a portion of the optical signal over at least a portion of the transmission fiber. In one particular embodiment, the pump signal operates to amplify the optical signal to approximately a maximum threshold power level as the pump signal and the optical signal traverse the portion of the transmission fiber.

摘要： An optical communication system includes a gain medium that receives optical signal(s) of one or more optical signal wavelengths. The system also includes pump source(s) that are capable of generating at least a first pump signal and a second pump signal. The first pump signal includes at least one integer Raman order wavelength that includes a Raman gain peak that is one stokes shift away from at least one of the one or more optical signal wavelengths. The second pump signal includes at least one fractional Raman order pump wavelength that includes a Raman gain peak that is a non-integer multiple of a stokes shift from each of the one or more optical signal wavelengths. Optionally, there might be one or more other pump signals that do not satisfy the criteria specified for the first pump signal or the second pump signal.
