Abstract

The invention discloses a second-order Raman amplifier and a control method thereof. The Raman light amplifier is arranged on a single disk, and the second-order Raman amplifier comprises a first-order pumping unit module, a second-order pumping unit module and a single disk management unit, wherein the first-order pumping unit module serves as a pumping light source of signal wavelength, and the second-order pumping unit module serves as a pumping light source of first-order pumping unit pumping light wavelength and is only used for conducting Raman amplification on the pumping light of the first-order pumping unit module. The first-order pumping unit module controls the second-order pumping unit module through an electrical interface mutually connected with the second-order pumping unit module. By the adoption of the second-order Raman amplifier and the control method, the switching state of a second-order pumping unit can be effectively controlled, and when an optical-fiber circuit gives an LOS alarm, the power of the pumping units can be rapidly and effectively cut off to achieve a laser safety function.

Description

technical field [0001] The invention relates to an optical communication device and a control method thereof, in particular to a second-order Raman optical fiber amplifier in an optical fiber communication system and a control method thereof, and the invention belongs to the communication field. Background technique [0002] At present, the optical network is developing in the direction of large capacity. The capacity of the backbone network is increasing, the number of channels is increasing, and the span of non-repeater optical transmission is increasing. The gain and power requirements of various optical amplifiers are further improved. Fiber Raman Amplifier (FRA for short) plays an important role in optical transmission systems because of its extremely low noise index. The industry puts forward new requirements for its gain range and requires continuous improvement of its gain index. Conventional Raman pump sources are composed of multi-wavelength lasers of 14xx nm (wit...
