An optical transceiver module is a high-tech active device
which is low in power consumption and small in size.Its emergence has promoted the development of optical transmission systems
so its performance test is of great significance.In this paper
the performances of an optical transceiver module are tested on an Automatic Test System(ATS) controlled by LABVIEW software.ATS device connection diagram is first designed and its principle explained.And then OC3-IR module is tested in three different temperatures by using LABVIEW.The test results show that the test is a success.
