Abstract: A Raman amplified transmission includes at least two pump sources to provide amplification to optical signals residing in the C-band (1530 - 1562nm) and L-band (1574 - 1604nm). The pump signals are chosen so as to provide for a relatively flat and wide composite gain spectrum with a width at least 50% greater than that generated by a monochromatic pump, while also chosen so as to prevent any four-wave mixing products from being in either the C- or L-bands.

Abstract: An optical transmission system is formed to include an optical phase conjugator (200) at alternate repeater sites to minimize the presence of four-wave mixing and other Kerr effect nonlinearities in systems using optical fiber transmission paths (particularly in systems using DWDM and launching relatively high power signals into the low dispersion fiber). Raman gain is included in each fiber span (or in alternate fiber spans) so as to provide a "negative absorption" along the length of the fiber and thereby provide for essentially symmetrical power distribution along the length of each span, where the presence of such a symmetric power distribution on each side of an optical phase conjugator (200) has been found to significantly improve its performance.

Abstract: A fiber Raman amplifier is configured to use a co-propagating Raman pump source, which may be beneficial in a variety of system configurations (for example, in bidirectional communication systems). By carefully configuring the pump source characteristics, sufficient optical gain can be achieved in the co-propagating arrangement, the characteristics including: (1) using an optical pump power of at least 50mW, (2) having a relatively large spectral bandwidth within the pump (to suppress SBS); and (3) a frequency difference between all longitudinal pump modes of each pump laser being separated by at least the walk-off frequency between the pump laser frequency and the signal frequency, and all intense longitudinal modes between different pump lasers being separated by at least the electrical bandwidth of the communication system.
