Raman optical fiber amplifier using erbium doped fiber |
摘要 |
A Raman optical-fiber amplifier used in a wavelength-division-multiplexing optical communication system is provided. The inventive amplifier includes an optical transmitter for transmitting wavelength-division-multiplexed optical signals through an optical fiber and an optical receiver for receiving the optical signals through the optical fiber, and further comprises an erbium-doped fiber which Raman-amplifies and outputs optical signals inputted through the first end of the erbium-doped fiber amplifier connected with the optical fiber; a pumping source which outputs pump light with a predetermined wavelength so as to Raman-pump the erbium-doped fiber; and, a wavelength-selective coupler which outputs the pump light to be introduced into the erbium-doped fiber.
