Temperature dependence of macrobending loss in all-fiber bend loss edge filter

摘要

A theoretical model for macrobending-induced temperature dependent loss (TDL) for a standard single-mode fiber (SMF28) with dual coating layers is presented, with good agreement demonstrated between theoretical calculations and experimental results. The impact of temperature on two examples of an all-fiber based edge filter is also investigated theoretically and experimentally and using the developed model, it is shown that it is possible to predict the impact of temperature variations on an all-fiber based edge filter.
