Optical Transceiver Checkers

The GIGALIGHT optical transceiver checkers are used to test optical transceivers, AOC and DAC. The checkers can read and display the detailed information of the EEPROM inside the optical module, including product model, supplier name, product description and operating temperature range, etc., and monitor all DDM information. If you know the password of the optical module, you can use the checker to change the EEPROM information of the module.
