CUSTOM PHOTON COUNTING OTDR FOR OPTICAL C-BAND

Marek Hlaváč - Jozef Jasenek - Jozefa Červeňová

   The design of an experimental device for photon counting OTDR is presented. The device features high degrees of freedom in the choice of measurement strategy, which is commonly not possible with the commercial OTDRs. This allows investigations of different methods of data acquisition from the selected portion of the fiber. The device also provides a set of features for studying single photon detection using gated Peltier cooled avalanche photodiodes.

Keywords: distributed fiber optic sensing, photon counting, OTDR, single photon avalanche diode, active quenching circuit
