Wavelength recording method and optical module distinguishing method

Abstract

The invention discloses a wavelength recording method and an optical module discrimination method, and the recording method comprises the steps: obtaining a to-be-stored wavelength value represented by a decimal system, wherein the to-be-stored wavelength value is the wavelength value of an optical signal transmitted by an optical module; converting the data before a decimal point in the to-be-stored wavelength value represented by the decimal system into a hexadecimal form and then stored in a first area in the optical module, wherein the first area is an area used by protocol division in the optical module and used for storing the to-be-stored wavelength value in an integer form; converting data after the decimal point in the to-be-stored wavelength value represented by the decimal system into a hexadecimal form, and storing the data in a second area in the optical module, wherein the second area is an area which is not divided and used by the protocol in the optical module. In the application, the data after the decimal point in the to-be-stored wavelength value represented by the decimal system is converted into the hexadecimal form and then is stored in the undivided and used area in the optical module, so the accuracy of wavelength recording is improved.

Description

technical field [0001] The present application relates to network communication technology, in particular to a wavelength recording method and an optical module identification method. Background technique [0002] With the rapid development of optical module packaging types, the packaging of optical modules is also slowly developing towards miniaturization. Optical modules in traditional miniaturized packages need to follow traditional standard protocols. [0003] The optical module follows the traditional standard protocol, and the wavelength value of the optical signal processed by the optical module needs to be converted into a hexadecimal coded form according to the traditional standard protocol, and stored in the storage area of ​​the optical module. However, in the decimal system, no matter what length unit is used, the wavelength of light may not be an integer value. For example, even if the unit is nanometer (nm), the wavelength of light may be 1596.34nm. In this c...

Problems solved by technology

[0004] It can be seen from this that with this storage method, only the approximate value of the wavelength value can be stored in the storage area of ​​the optical module, and the wavelength value of the optical signal processed by the optical module cannot be accurately recorded, so that the accuracy of recording the wavelength value of the optical signal processed by the optical module cannot be accurately recorded.
