Distributed fiber optical sensing

Polarization-based, multi-span sensing over a link without reflection-back circuits is demonstrated experimentally. It is shown that distributed reflection from Rayleigh scattering can serve as an alternative to reflectors after spatial averaging of received state-of-polarization.
