Embodiment Construction
[0055] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0056] In order to better understand a method for labeling fiber wavelengths disclosed in the embodiments of the present invention, the present invention provides Figure 4 The flow chart of the method for labeling the wavelength of the fiber is shown, from Figure 4 It can be known that a method for labeling optical fiber wavelengths in the present invention mainly consists of two execution subjects, the two execution subjects are respectively the sending end and the receiving end, in order to transfer the spreading code from the sending end to the receiving end, the spreading code is embedded into the sending end In the top-tuning signal, the way of direct spread spectrum is ado...

The invention relates to a method for labeling the wavelength of an optical fiber, which includes deploying extension codes at both the sending end and the receiving end; sending the signal code, and using the spreading code at the sending end to perform extended processing on the signal code; using the extended signal code to process the optical signal Perform top adjustment processing, send the top adjustment processed optical signal to the receiving end, and the receiving end selects the spreading code of the receiving end to despread the signal code, obtains the original signal code of the sending end, and obtains the corresponding signal according to the spreading code of the receiving end wavelength. The present invention uses the spread code corresponding to the wavelength to spread and despread the signal code. Due to the spread of the spectrum, the modulation depth of the amplitude modulation signal can be greatly reduced so that the top modulation signal hardly affects the main signal, and the related It is easier to design and implement the filter, significantly reduces the complexity of hardware design, and realizes the use of extension codes for wavelength labeling.
Description
technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a method for labeling optical fiber wavelengths. Background technique [0002] In optical fiber communication, wavelength division multiplexing is widely used to increase the capacity of a single optical fiber. In order to effectively track and manage the wavelengths of light waves used in communication networks, it will undoubtedly bring great convenience for each light wave to have its own wavelength information. At present, the wavelength of the optical fiber is mostly marked with the top-tuning signal, that is, a small-amplitude low-frequency sinusoidal signal is superimposed for each wavelength. Marking, that is to say, the light wave carries its own wavelength information through the top tuning signal. [0003] The light wave signal after top adjustment is as follows: figure 1 shown. The top-tuned FM signal is a superimposed low-frequency sinusoidal ...
