Baseband signal sending device and method based on WDM, storage medium and electronic equipment

Abstract

The embodiment of the invention provides a baseband signal sending device and method based on WDM, a storage medium and electronic equipment. The device comprises a laser device, a light emitting control module and a light filtering assembly arranged on an output light path of the laser device. The light filtering assembly is used for allowing an optical signal with the wavelength within a presetwavelength range to pass through; and the light emitting control module, is used for acquiring a signal format of a to-be-sent baseband signal, and controlling the laser to output an optical signal with a first preset wavelength according to the signal format of the baseband signal to be sent, or an optical signal of a second preset wavelength, wherein the first preset wavelength is within a preset wavelength range of the light filtering assembly, the second preset wavelength is not within the preset wavelength range of the light filtering assembly, so as to solve the problems that the wavelength drift is serious, the communication quality of adjacent channels is influenced, and the optical fiber communication effect is further influenced when the switching between light emitting and non-light emitting is realized by turning on or turning off a laser.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a WDM-based baseband signal sending device, method, readable storage medium and electronic equipment. Background technique [0002] In the field of traditional optical fiber communication, how to make full use of optical fiber to increase its transmission capacity is one of the most common technical demands in the industry. Wavelength Division Multiplexing (WDM) technology is to combine two or more optical signals of different wavelengths through a multiplexer and send them together, and then transmit them in the same optical fiber. The receiving end separates the optical signals of different wavelengths through the optical wave demultiplexer, and then splits them to different receivers. [0003] In the transmission of optical signals by existing baseband signal transmission devices, there are bursts in the time domain. Specifically, in practice, as the sign...
