HIGH TEMPERATURE OPTICAL FIBRE

摘要

A glass fibre (10) consisting of a core (12) provided with cladding (14) is coated with a single coating (16) of a metal, alloy or dielectric capable of withstanding temperatures in excess of 300 DEG C and preferably 500 DEG C. The coating is deposited by a vapour phase reaction process occurring on the surface of the fibre. The fibre may be solid (as shown) or hollow.
