Polarization dispersion measurement in long single-mode fibers with zero dispersion wavelength at 1.5 µm

Abstract

Polarization dispersion in 1 km long single-mode fibers is measured by observing the wavelength dependence of fiber birefringence. A typical measured value is 0.24 ps/km at the 1.2 μm wavelength. The measured wavelength dependence of polarization dispersion is explained well by a theory taking into account elliptical core deformation. Fitted core ellipticity values for the two test fibers are 0.012 and 0.003.
