Hello, i've this problem and i will thank anyone with an idea: I need to make an optical bus, i 've an optical signal that have to be a trigger for 10 modules along 10Km or 30000 feet. Thus any receivers modules is isolated and can receive the optical signal (the trigger). The receiver is battery powered. My ideas are:
1) 10 optical led trasmitter and 10 optival reciver connect with multimode (it's hard long distance) 2) 1 laser and 10 beam splitter, 10 pin optical receiver with multimode or singlemode fiberAny help will be good. Matteo
