Distributed strain and temperature sensing over 100  km using tunable-wavelength OTDR based on MEMS filters

The possibility of distributed wide-range strain and temperature measurements in a 100 km long optical fiber using tunable-wavelength low-coherence optical time-domain reflectometer (OTDR) is demonstrated. The specified distance range is provided by employing two narrowband microelectromechanical sy...
