A novel optical fibre connecting component was fabricated by direct jacketing of silica glass single mode optical fibre (SMF) with a low expansion Li2O-Al2O3-SiO2 (LAS) glass ceramic. The durability of the glass ceramic jacketed SMF (GC-SMF) was evaluated by immersion, high temperature and damp heat tests. The GC-SMF displayed excellent stability in the configuration of its optical connecting endfaces in both the immersion test in hot acidic water and the high temperature endurance test at 500 deg C for 1 hour. It was confirmed that the GC-SMF is suitable for high power optical communication systems as a durable optical connecting component.
