Abstract
An extinction ratio testing system () includes a microcontroller (), an extinction ratio tester (), and a thermostat (). The microcontroller () controls the thermostat () to maintain an optical transceiver module () at a predetermined high temperature, and then the microcontroller () controls the extinction ratio tester () to test an extinction ratio of the optical transceiver module (). If the extinction ratio is lower than a standard extinction ratio, the microcontroller () controls the optical transceiver module () to increase a laser operating current () of the optical transceiver module () to increase the extinction ratio.
