[0029] By setting the heat dissipation mechanism 2, in the use of the optical communication module test device, the first step, the optical communication module to be tested is accurately connected with the test interface group 297 on the device, after the connection is correct, the optical module test board 295 is started, and the test of the optical communication module is started. In the test process, the optical module test board 295 will generate heat. In order to effectively dissipate heat, the following operations can be performed: start the motor 24.
