Device and method for testing self-recovery performance of optical module

Abstract

The invention discloses an optical module self-recovery performance test device and method and relates to the communication field. The test device comprises a power supply and a signal generator. Thetest device also comprises a test board and an optical module interface. The test board is provided with a power interface, a high-speed differential signal interface and an indicator lamp unit, wherein the power interface is connected with the power supply, and the high-speed differential signal interface is connected with the signal generator; the optical module interface is arranged on the testboard; the optical module interface is connected with the power interface, the high-speed differential signal interface and the indicator lamp unit; an optical module to be tested is connected with the optical module interface; and the optical module interface is used for inputting test voltage generated by the power supply and high-speed differential signals generated by the signal generator into the optical module to be tested, and is also used for receiving output signals of a state pin of the optical module to be tested and outputting the output signals to the indicator lamp unit. The test device and method can fully verify power supply abnormity and self-recovery performance of the optical module after recovery, thereby preventing the problem that fault cannot be recovered in practical application and ensuring communication quality.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a device and method for testing the self-recovery performance of an optical module.
