The light source module 2 emits light onto the quartz glass tube 4, and the optical fiber coated with the coating sequentially passes through the second through hole and the first through hole. When the optical fiber is cured, the first optical power detection module 6 receives the first optical signal transmitted by the end face of the quartz glass tube 4, and obtains the first optical power of the first optical signal, and the optical power transmitted by the quartz glass tube 4 is basically the same as the optical power in the box body 1, so that the real-time detection of the overall optical power of the light source module 2 in the box body 1 is realized while the optical fiber is cured, and the curing quality of the optical fiber is favorably ensured.
In an optional embodiment, the detection method of the optical fiber curing optical power detection apparatus provided in the embodiment of the present invention further includes:
the quartz glass rod 8 is arranged in the box body 1, one end of the second optical power detection module 9 is attached to one end of the quartz glass rod 8, and the light source module 2 emits light to the quartz glass rod 8;
the second optical power detection module 9 determines a second optical power based on the received second optical signal conducted by the quartz glass rod 8.
When the optical fiber curing optical power detection device is in a production stop mode, the quartz glass rod 8 is fixed at the wire drawing channel 3, one end of the quartz glass rod 8 is located outside the box body 1, one end face of the second optical power detection module 9 is attached to one end face of the quartz glass rod 8, the second optical power detection module 9 receives a second optical signal transmitted by the end face of the quartz glass rod 8, and second optical power of the second optical signal is obtained, so that the detection of the overall optical power of the light source module 2 in the box body 1 in the production stop mode is realized, and optical power information in the box body 1 can be provided before subsequent optical fiber curing production.
