Optical module test method

Abstract

The invention discloses a method for testing an optical module, which includes the following steps: performing at least one test item on at least one optical module to be tested with a unique serial number under a plurality of different ambient temperatures; The serial number of the optical module to be tested is associated with the test data of each test item and stored in the local database in the form of an index table. The test data of each test item is indexed by the serial number of the optical module to be tested. The optical module to be tested The serial number of the module is indexed by the ambient temperature; when the test is interrupted and the test is retested, it is determined according to the index table stored in the local database which optical modules to be tested have not completed all the test items at each The light metering module continues testing. The method of the invention does not need to retest the optical modules that have completed all tests, avoids repeated testing, and improves testing efficiency.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module testing method. Background technique [0002] In the process of producing communication optical modules, it is necessary to test various performance parameters of the optical module, such as testing the optical module's transmitted optical power, received optical power, and optical eye diagram. Before the test, install multiple optical modules to be tested on the test board. The optical modules on the test board are connected to various optical path test instruments through multi-channel optical switches, and the test host is connected to the test board. carry out testing. At present, during the testing process, if there is a failure such as a power outage, workers need to re-test all optical modules, which wastes manpower and material resources, increases production costs, and greatly reduces the efficiency of optical module testing.
