Most of the current laser equipment manufacturers adopt a photoelectric probe to acquire optical signals of optical fiber transmission power, convert the optical signals into electric signals and finally realize digital signal output through subsequent circuit operation processing, but because laser has strong directivity and is strongly related to the processing mode and welding loss of optical fibers to be detected, and the proportion difference of leakage of the same-power laser during transmission in an optical fiber core and an optical fiber cladding is large, the calibration of acquired data of the optical fiber transmission power between different machine stations and at different positions of the same machine station has certain difficulty.

At present, data between different machines is generally calibrated after electric signals are processed through circuit gain, and data between the same machines is generally calibrated through adding attenuation sheets to the selected different photoelectric probes.

Therefore, an adjustable optical fiber transmission power detector is needed, which is adjustable at an optical signal acquisition source to adjust the electrical signal output of the photoelectric probe to a proper interval, so as to facilitate subsequent calibration.
