Light module test method

Abstract

The invention discloses a light module test method which includes the following steps: conducting test of at least one test item on at least one light module to be tested and with unique serial number under multiple different environment temperatures, correlating environment temperature, serial number of the light module to be detected and test data of each test item in current test, storing the data in a local database in index table mode, enabling the test data of each test item to utilize the serial number of the light module to be tested as index and the serial number of the light module to be tested to utilize the environment temperature as index, searching and judging which light modules to be tested under each environment do not finish all test items according to an index table stored in the local database and continue testing on the light modules to be tested and not finishing all the test items when the test is suspended and restarted. The light module test method does not require testing the light modules finishing all tests, avoids repeated test and improves test efficiency.

Description

Technical field [0001] The invention involves the field of optical communication technology and specially involves a test method of light module. Background technique [0002] In the process of production and communication optical modules, various performance parameters need to be performed on the optical module, such as testing of optical power, receiving optical power, and optical diagram of the optical module.Before the test, install multiple light modules on the test board. The light module located on the test board connects to various optical road test instruments through multiple light switches.carry out testing.During the test process, if there are faults such as power outages, workers need to re -test all the light modules, waste human resources, increase production costs, and reduce the efficiency of optical modules. Invention content [0003] The purpose of the present invention is to overcome the above deficiencies in the existing technology, and provide a test method...

AI Technical Summary

Problems solved by technology

At present, during the testing process, if there are failures such as power outages, workers need to retest all optical modules, which wastes manpower and material resources, increases production costs, and greatly reduces the efficiency of optical module testing.
