The present invention discloses a phase-shifted fiber bragg grating-based multi-wavelength and narrow-linewidth annular cavity fiber laser system. The system comprises the steps of shooting the pump light to an annular cavity through a wavelength division multiplexer, and then feeding the pump light into an erbium-doped optical fiber; feeding the light shot out of the erbium-doped optical fiber into a light circulator to enter a plurality of series-connected fiber bragg gratings; and feeding the light reflected back by the fiber gratings into a phase-shifted optical fiber grating through the circulator. The reflection peak of the fiber gratings is corresponding to the phase-shifted peak of the corresponding phase-shifted fiber grating, and the bandwidth of the fiber gratings is reasonably selected. The light transmitted out of the phase-shifted fiber grating is input into the upper port of a coupler, and then enters an optical isolator. After that, the light enters the wavelength division multiplexer, so that one cycle is completed. The above steps are repeated. When the gain is greater than the loss, the obtained laser is outputted through the lower port of the coupler. According to the technical scheme of the invention, multiple phase-shifted optical fiber gratings and corresponding multi-fiber gratings are adopted, so that multi-wavelength and narrow-linewidth lasers can be simultaneously outputted.

Therefore, multi-service carrying of the ITV service and the internet service of the power line carrier communication wireless AP terminal device can be realized efficiently.
