Abstract

The invention discloses an optical module and an initialization method and device thereof. The initialization method of the optical module comprises the following steps of: setting an initialization voltage threshold of a circuit unit to be initialized; acquiring a power supply voltage value of the circuit unit to be initialized; comparing the initialization voltage threshold of the circuit unit to be initialized with the acquired power supply voltage value; and when the acquired power supply voltage value is greater than the initialization voltage threshold, initializing a corresponding circuit unit by using a master processor of the optical module. The method and device disclosed by the invention can solve the problem that in the prior art, corresponding circuit units of an optical module can not be reliably initialized, thereby influencing the performance of an optical communication network.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular, to the initialization of an optical module, and more specifically, to an optical module and its initialization method and device. Background technique [0002] In recent years, the continuous expansion of the transmission capacity and the continuous improvement of the transmission rate of the main line of the information network have made the optical fiber communication the main transmission means of the modern information network, and the optical module, which is one of the core optoelectronic devices, is also developing rapidly at an astonishing speed. With the development of optical fiber communication, the application scenarios and usage environments of modern optical communication networks have become more complex, which puts forward extremely high requirements on the reliability of optical fiber network transmission. As one of the core optoelectronic dev...
