線性自適應(yīng)光保險絲的研制

為了保護光接收機，本文提出一種基于線性自適應(yīng)原理的光保險絲。首先，通
過波分復(fù)用技術(shù)，將用于檢測光功率的特定波長的“控制光信號”進行提取、采樣，并
且轉(zhuǎn)換為電信號進行變異性分析，然后通過自適應(yīng)光開關(guān)，建立一種“光保險絲”電路，這種“光保險絲”可以自動判斷光功率，在光功率過載的情況下，自動切斷光信號，從而保護了光接收機。

Abstract: In order to protect optical receiver, this paper presents a theory based on linear adaptive optical fuse. Firstly, through WDM technology will be used to detect the specific wavelength optical power to "control optical signal" extraction, sampling, and converted to a signal variability and correlation dimension analysis, then adaptive optical switching circuit, and a judge automatically cut-energy mutation Intelligent Light acceptable to the protection of the "light fuse" role
KeyWord: light fuse，linear adaptive theory，correlation dimension analysis
