Abstract

The invention relates to a method for carrying out optical module two-step verification through utilization of a data interface. The method comprises the following steps of S01, inserting an optical module into a terminal device and judging legality of the optical module by the terminal device through the data interface between the optical module and the terminal device; S02, finishing a first-step verification program if the optical module is legal, entering a next-step verification program, and indicating that the first-step verification program is not finished if the optical module is illegal; S03, judging the legality of the terminal device by the optical module through the data interface after the optical module is verified as legality; and S04, finishing a second-step verification program if the terminal device is legal, and indicating that the second-step verification program is not finished if the terminal device is illegal. The method has the beneficial effects that through two-step verification programs, the terminal device and the optical module carry out mutual verification, the break difficulty is greatly increased, the illegal optical module or the illegal terminal device is effectively verified, and the legality and compatibility of the optical module and the terminal device are ensured.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method for performing two-step verification of an optical module by using a data interface. Background technique [0002] With the development of information transmission and exchange towards optical network, optical fiber communication has become the main transmission means of modern information network. Demand, the optical module is constantly developing in the direction of intelligence and high speed. [0003] At present, optical modules that support hot plugging have been widely used. Due to the fact that there are many manufacturers of optical modules, the quality of optical module products varies. There are many fake and shoddy products produced by unqualified manufacturers on the market. These optical modules can be compatible with equipment. However, the reliability of the module cannot be guaranteed, which will affect the reliability of the entire system...
