This paper reviews recent developments in distributed fiber optic sensing systems (DFOSS) employing optical time domain reflectometry (OTDR), polarization optical time domain reflectometry (POTDR), and frequency domain reflectometry (OFDR) techniques. Such systems can time - and/or frequency multiplex a large number of sensors distributed along an optical fiber, and offer unique advantages over conventional multiplexed sensing technology.
