摘要：

A major cause of loss in fluoride fibres has been extrinsic scatter from bubbles trapped in preforms during casting. A new reduced pressure casting (RPC) technique has been developed to eliminate bubbles, and the minimum fibre loss has been reduced to 0.65±0.25 dB/km at 2.59μm, measured over a 110 m length of fibre. © 1990, The Institution of Electrical Engineers.
