Polarisation measurements on monomode fibres using optical time-domain reflectometry

摘要

The feasibility of polarisation optical time-domain reflectometry in single-mode fibres is demonstrated. Polarisation analysis of the backscattered light clearly shows the evolution of the state of polarisation in the fibre. It is further shown that the polarised nature of the scatter return from single-mode fibres can cause errors in conventional backscatter measurements.
