Abstract

The invention provides a topping depth testing device and method. The device comprises a photoelectric detection unit which is used for converting an optical signal into an electric signal, carrying out the filtering and shaping of the electric signal, and outputting a square-wave voltage signal; A sampling calculation unit is used for converting the sampled high-low level signals into corresponding level values after sampling through an ADC interface, and the MCU is used for calculating a topping depth value according to a formula; A result display module is used for displaying and outputting the topping depth calculation result of the sampling calculation unit on a display screen. According to the scheme, the topping depth testing process of the optical module can be simplified, and the accuracy and reliability of a measurement result are guaranteed.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a device and method for testing the depth of top adjustment. Background technique [0002] From the second half of 2019, China Mobile began to promote the use of MWDM optical modules with top adjustment function in the field of 5G fronthaul, and released a series of application enterprise and industry standards. Among them, for the amplitude modulation module, the specification definition of top adjustment depth 3% to 5%. At present, the test method for the depth of the top adjustment has been relatively cumbersome, and there are two commonly used methods: one is to test with an optical probe and an oscilloscope, and then perform manual calculation; the other is to fly the line from the receiving RSS I pin of the module , Test the high and low levels with an oscilloscope, and then perform manual calculations. However, the testing process of the top adjustment depth in these...
