摘要： A transmission cable using optical fibre for conveying the information consists of fibres loosely laid in helical grooves of a core so that the fibre will undulate within the groove due to over-length given by pretwisting of the fibre and curvature of the groove flanks. Reduction of the contact surface between the fibre and the core improves the electrical characteristics and reduces the sensitivity of the cable to mechanical stress.
