Pumping source aging test device

The utility model provides a pumping source aging test device, which is characterized in that a beam combiner is arranged in a box body, an emergent optical fiber is arranged on the light emitting side of the beam combiner to be connected with a power meter, multiple paths of incident optical fibers are arranged, one end of each of the multiple paths of incident optical fibers is connected with the light incident side of the beam combiner, and the other end of each of the multiple paths of incident optical fibers is connected with a pumping source to be tested through a joint. Pump light beams emitted by the plurality of pumping sources to be tested are transmitted to the beam combiner through the incident optical fiber, and the beam combiner transmits the pump light beams to the power meter through the emergent optical fiber, so that the aging test of the pumping sources to be tested is realized, the aging test of the plurality of pumping sources to be tested is realized at the same time, and the problem of
