Abstract: A pump light source includes a light emitting unit, a mode converter, and an optical interface unit. The light emitting unit is configured to output multi-mode pump light. The mode converter is configured to convert the multi-mode pump light output by the light emitting unit into a plurality of channels of single-mode pump light and output the plurality of channels of single-mode pump light. The optical interface unit is connected to an optical amplifier via an optical transmission medium to provide at least one channel of single-mode pump light in the plurality of channels of single-mode pump light for a corresponding optical amplifier via the optical transmission medium.
