Temperature sensitivity of POF links for avionics applications

We present an experimental study of the temperature sensitivity of three different step-index 1-mm PMMA fibers. Two of these fibers have a special jacket to sustain high temperatures: BH-4001 and LHXE-4001 and the other is a standard, GH-4001 fiber with a polyethylene jacket. We show that the fibers perform well within the manufacturer specified temperature operating ranges. Predictably, higher than specified temperatures can result in permanent damage and permanent performance degradation. This work expands our previous work on modelling POF on various fiber types and lengths, focusing on the short links found on airplanes.
