The temperature dependence of polarization dependent loss (PDL) for a macrobending standard singlemode fiber (SMF28) is investigated both theoretically and experimentally. The experimental results show an overall agreement with the proposed theoretical model over a temperature range from 0 to 70oC. An SMF28 based edge filter is used as an example regarding temperature dependent PDL performance. It is shown that the temperature variations have a significant influence on the polarization dependence of macrobending loss, and further impact on such a fiber bend loss edge filter used in a wavelength measurement application. It is also concluded that by using proposed models, such a temperature dependent birefringence can be beneficially predicted in bending fiber sensing applications.
