System and method for testing single-fiber bidirectional optical modules

Abstract

The invention provides a system and a method for testing single-fiber bidirectional optical modules on the basis of an optical fiber circulator. The system and the method are characterized in that the system for testing the single-fiber bidirectional optical modules comprises an error detector, an optical source, a to-be-tested module, a computer, an attenuator, the optical fiber circulator, an optical divider, an oscilloscope and an optical power meter, so that the system for testing transmission parameters and receiving parameters of the module is formed. The system and the method for testing the single-fiber bidirectional optical modules have the advantages that optical fibers are not required to be changed in an integral module testing procedure, transmission indexes of the optical module can be tested, receiving indexes of the optical modules can be measured, adverse factors (such as end surface pollution) caused in a measurement procedure are effectively avoided, accordingly, the stability of test results is guaranteed, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a test system and a test method for a single-fiber bidirectional optical module. Background technique [0002] Because the single-fiber bidirectional optical module is an optical module that uses one optical fiber to transmit and receive, so in the production process of the optical module, the optical fiber needs to be replaced when testing the emission index and receiving index, which brings inconvenience to the production and may cause pollution. The end face of the optical fiber will affect the test results. At the same time, the process of replacing the optical fiber will also affect the test efficiency. If it can be guaranteed that the single-fiber bidirectional optical module does not change the optical fiber during the test, it will not only reduce the number of end face wiping, avoid end face contamination, but also greatly improve production efficiency.
