Abstract

The invention discloses a method for measuring burst mode light power and a device thereof. A photodetector receives an optical signal transmitted by an optical network terminal and generates photocurrent; mirror current source generates mirror current; the mirror current is converted into a voltage signal in an amplification way and transmitted to a sample holding unit; a system hoist controls the sample holding unit at sampling mode; when the voltage signal is stable, the system hoist controls the sample holding unit at hold mode and controls an analog-digital conversion unit to convert the voltage signal into digital quantity; and a microcontroller obtains corresponding light power magnitude after receiving the digital quantity according to mapping relationship, and outputs the light power magnitude to the system hoist by a two-wire serial bus (I<2>C). By adopting the technical scheme, light signal power with hundreds of nanoseconds of length can be measured without expensive high speed device, and lower energy consumption can be realized while reducing cost.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a burst mode optical power measurement method and device. technical background [0002] The passive optical network is a point-to-multipoint system. An optical line terminal (OLT) is connected to multiple optical network terminals (ONT) through a tree-shaped optical fiber link, which not only shares part of the optical fiber link resources, but also distributes the optical line terminal (OLT) cost. At the same time, because the passive optical network does not require midway photoelectric relay or signal processing, it has the advantages of low network construction cost and simple maintenance. [0003] In terms of network technology, in the upstream direction of the passive optical network (PON), the data transmission from each optical network terminal (ONT) to the optical line terminal (OLT) adopts the method of time division multiple access (TDMA), which is also a...
