M. Wegmuller et al., Analysis of the polarization evolution in a ribbon cable using high-resolution coherent OFDR, IEEE PHOTON, 13(2), 2001, pp. 145-147
Exploiting the inherent polarization dependence and good spatial resolution
of optical frequency domain reflectometry (OFDR), the beatlength in a ribb
on fiber can be straightforwardly measured. The results clearly show the di
fferent amount of polarization ordering for inner and outer ribbon fibers d
ue to the stress-induced birefringence from the common outer coating.
