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
