Abstract
Methods for providing flammability protection for plastic optical fiber (POF) embedded inside avionics line replaceable units (LRUs) or other equipment used in airborne vehicles such as commercial or fighter aircrafts. A thin and flexible flammability protection tube is placed around the POF. In one proposed implementation, a very thin (100 to 250 microns in wall thickness) polyimide tube is placed outside and around the POF cable embedded inside an LRU or other equipment. The thin-walled polyimide tube does not diminish the flexibility of the POF cable.
