Dispersion-compensated raman optical fiber amplifier |
摘要 |
Disclosed is a dispersion-compensating, Raman optical fiber amplifier used in an optical communications system of the type having an optical transmission block for transmitting wavelength division multiplexed optical signals through a fiber and an optical receiving block for receiving the optical signals through the fiber. The inventive amplifier includes: a circulator for outputting optical signals that are inputted through a first end connected to the fiber to a second end and for outputting optical signals that are reflected through the second end to a third end connected to the fiber; a dispersion-compensating fiber for compensating optical signals passing therethrough and for outputting optical signals after performing a Raman amplification; a pumping light source for pumping the dispersion-compensating fiber and for outputting a pumping light having a designated wavelength; a wavelength selective coupler for outputting the pumping light to the dispersion-compensating fiber; and, a reflector for reflecting the Raman pumped optical signals and for reflecting the optical signals back into the dispersion-compensating fiber.
