Abstract

This work describes a non-continuous sensor operating technique in order to achieve a long reach sensing system, using power over fiber (PoF) in single mode fiber (SMF). Due to the use of super-capacitors and logical circuits in the sensor unit, the energy provided by PoF can be stored and used in an appropriated time. We demonstrated this approach with a micro video camera sensor powered by a 4.4-km SMF link in laboratory and by a 1.6-km link using optical ground wire cable (OPWG), installed between an electrical power substation and a tower of 138-kV overhead transmission line (OTL).
