Optical power automatic calibration system and method

Abstract

The invention relates to the technical field of optical communication, in particular to an optical power automatic calibration system and method. The system is characterized in that the system comprises a light source module 1, an electric modulation attenuator 2, a one-input two-output light beam splitter 3, a micro control unit MCU4, an output photoelectric detector 5, an input photoelectric detector 6, a system serial interface 7, an ADC analog-to-digital conversion module 8, a temperature detection control circuit 9, a current driving circuit 10 and an analog voltage control circuit 14. According to the novel optical power automatic calibration system and method provided by the invention, a PID system with built-in control detection is adopted, so that the output optical power is prevented from drifting and distorting. Output and input of optical power are adjusted in a full-automatic mode, and the manual adjusting time is greatly shortened. Functions of a light source, a power meter, an attenuator and the like are integrated into a set of system and are controlled by a micro-control unit, so that the occupied space is small, and the testing method is simple.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical power automatic calibration system and method. Background technique [0002] With the advent of the 5G era, the optical fiber communication network has been greatly developed. Active optical fiber communication equipment such as light sources, optical power meters, optical fiber amplifiers, and optical modules have become indispensable instruments and equipment in optical fiber communication and testing. It has important applications in the fields of large-scale construction and maintenance, multi-input and output testing of optical fiber arrays, and mass testing of optical active and passive devices. In order to improve the optical power accuracy of optical communication equipment, it is necessary to calibrate the input and output optical power of optical communication equipment before leaving the factory. However, due to the uncertainty of the working ...
