Abstract:
A network healing smart fiber optic switch for fast, automatic switching between a plurality of paths comprising an optical transmission line, each of the plurality of paths comprising a fiber optic cable, said network healing smart fiber optic switch comprising:a plurality of splitters, each of said plurality of splitters having a splitter input from said fiber optic cable and outputting a first splitter output signal and a second splitter output signal; a controller responsive to each said second splitter output signal from said plurality of splitters, said controller outputting a controller output signal, said controller maintaining said controller output signal for a predetermined period irrespective of any change to said second splitter output signal, whereby any tendency towards oscillation of said control output signal is minimized; and an optical switch responsive to said controller output signal, said optical switch capable of switching any of said first splitter output signal to an optical switch output.
