Problems solved by technology
[0005] The embodiment of the present application provides an optical module and a dual-MCU-based automatic wavelength polling method at both ends of the optical module to solve the problem that the two ends cannot be established when there is no upper computer, or when there is an upper computer but does not participate in the link link between the modules at both ends. The link link at the end leads to the problem that data communication cannot be carried out

Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0035] One of the core links of optical fiber communication is the conversion of photoelectric signals. Optical fiber communication uses optical signals carrying information to be transmitted in optical fibers / optical waveguides, and low-cost, low-loss information transmission can be achieved by using the passive transmission characteristics of light in optical fibers. However, information processing equipment such as computers use electrical signals, which requires mutual conversion betwee...

The invention provides an optical module and an automatic wavelength polling method based on a double-MCU optical module, a sending end sends a first optical signal carrying a first low-frequency message channel to a receiving end, and the first low-frequency message channel is used for indicating first wavelength information and a wavelength switching instruction; a second slave MCU of the receiving end optical module receives and analyzes the first wavelength information and the wavelength switching instruction, a second master MCU sets back transmission wavelength information according to the first wavelength information and the wavelength switching instruction, and the second slave MCU sends a second optical signal carrying a second low-frequency message channel according to the back transmission wavelength information; and after receiving the second optical signal, the first slave MCU of the transmitting end optical module analyzes the second optical signal to obtain return wavelength information, and the first master MCU judges whether to poll the switching wavelength information according to the return wavelength information. According to the application, the wavelength polling online function is automatically operated through the master MCU and the slave MCU of the optical module, the wavelength information needing to be set currently is confirmed, and finally the link between the two ends is established.
Description
