Abstract: An apparatus for transporting an optical signal is provided comprising at least two sections of optical fiber, a directional wavelength selector positioned between the at least two sections of optical fiber wherein the directional wavelength selector selectively blocks wavelengths propagating in a reverse direction, and a pump light emitting device optically coupled to the optical fiber.

Abstract: A double pumped Raman amplifier is provided that increases gain over a same length of gain fiber without significantly increasing a percentage of noise. The amplifier may include a source of pump light coupled to the output end of a coil of Raman gain fiber, and a reflector coupled to the input end of the coil which may be either a mirror, or a fiber Bragg grating. Alternatively, a beam splitter may be connected to the source of pump light and the resulting split output may be coupled to both the input and output ends of the gain fiber. The increase in amplification efficiency allows the optical fiber used in components such as dispersion compensating modules to also be used as Raman gain fiber in such amplifiers.
