Abstract

The invention provides a BOSA receiving power calibration method and device, and the method comprises the steps: determining a calibration type according to BOSA parameter information; determining calibration parameters according to the following objects: a calibration type, first sampling information and second sampling information, wherein the first sampling information is used for indicating measurement ADC information measured in a preset sampling point, and the second sampling information is used for indicating receiving optical power information corresponding to the preset sampling point; and determining a relationship between the optical power information and the ADC information according to the calibration parameters, and performing bidirectional optical subsystem BOSA receiving power calibration according to the relationship between the optical power information and the ADC information. According to the invention, the problem of inaccurate BOSA receiving power calibration caused by the fact that factors possibly influencing optical power information and ADC information are not comprehensively considered in the BOSA receiving power calibration process in the related technology is solved, and the effect of improving the BOSA receiving power calibration accuracy is achieved.

Description

Technical field [0001] The present invention relates to the field of microelectronics, and in particular, to a method of receiving power calibration means and apparatus for BOSA. Background technique [0002] With the development of fiber optic communication technology and the construction of the access network, in order to achieve the full range of fiber to the Fibreto the Home, FTTH), the Passive Optical Network, PON is constantly displayed Terminal users provide reliable data, voice, and video communication capabilities. In the current PON technology, Gigabit Passive Optical Network, GPON and Ethernet Passical Network (EPON) are currently two mainstream efficient broadband access technology. [0003] The implementation of the above PON technology can use a PON single board. For the PON single board, it can be implemented with the Bi-Directional Optical Sub-Assembly, BOSA) to achieve an Optical Lineterminal, OLT. connection. The setting of the BOSA replaces the traditional opti...
