ONT power calibration method based on data analysis

Abstract

The invention discloses an ONT power calibration method based on data analysis. The method comprises the steps that an initial set value X1 and a stepping value Y are set in an ONT register in advance, and initial power P1 is obtained through a production test platform, wherein X1 and P1 form a data group R1, and the production test platform sends a target data reading request to a server according to the data group R1; the server receives the target data reading request and queries whether or not the data group R1 exists in a server database; if not, a dichotomy method is used for measurement; if yes, a target value is used for measurement. According to the method, the process of dichotomy calibration is mainly used for obtaining enough data samples at the beginning, when more and more data samples are obtained, testing is conducted basically according to the process of searching the samples for the target value, and at this moment, the efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of product performance testing, in particular to a method for calibrating ONT power based on data analysis. Background technique [0002] With the development of modern society, users have higher and higher requirements for communication bandwidth. At present, FTTH (fiber to the home, fiber-to-the-home) is still the best wired broadband solution. The market's demand for ONT (Optical Network Termination) Demand is also growing explosively, and ONT has become the main product of manufacturing enterprises in the Internet communication industry. Therefore, for factories, only by producing ONT with high quality and low cost can they improve their market competitiveness. Increase, high efficiency and automation of production testing are the basic needs in the current environment. Based on cost considerations, the current mainstream ONT products all adopt the BOB (bosa on board) scheme, and basically use the APD a...

[0011] In practice, due to the high sensitivity of optical devices, batches of materials, and the environment will have a great impact on the calibration value. Through the analysis of production data, it is found that the final target value of each ONT is very different. Using the above two methods to calibrate the basic It takes several consecutive times to find the final target value. In extreme cases, more than 10 times will occur, which greatly reduces the efficiency of production testing.
