Abstract
New LED transmitters have been used to develop a new method of fast an alog transmission of PMT pulses over large distances. The transmitters , consisting basically of InGaAsP LEDs with the maximum emission of li ght at 1300 nm, allow the transmission of fast photomultiplier pulses over distances of more than 2 km. The shape of the photomultiplier pul ses is maintained, with an attenuation less than 1 dB/km. Typical appl ications of analog optical signal transmission are surface air shower detectors and under water/ice neutrino experiments, which measure fast Cherenkov or scintillator pulses at large detector distances to the c entral DAQ system.
