Embodiment Construction

[0036] 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.

[0037] 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...

Abstract

The invention provides an optical module and an automatic wavelength communication method based on a double-MCU optical module, a sending end optical module sends a first optical signal carrying a first low-frequency message channel to a receiving end optical module, and the first low-frequency message channel is used for indicating first wavelength information; a second slave MCU of the receiving end optical module receives the first optical signal and analyzes the first optical signal to obtain first wavelength information, a second master MCU of the receiving end optical module sets second wavelength information according to the first wavelength information, and the second slave MCU sends a second optical signal carrying a second low-frequency message channel according to the second 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 second wavelength information, and the first master MCU realizes wavelength communication according to the second wavelength information. According to the invention, links are established between the master and slave MCUs of the transmitting end optical module and the master and slave MCUs of the receiving end optical module according to the interaction of the master and slave MCUs, and the automatic wavelength communication function of the systems at the two ends is realized.
