Abstract
Ultralow-loss single-mode-fibre cables specially designed for the 1.5 μm region were fabricated. The fibre parameters are a mode-field radius of 6 μm and an effective cutoff wavelength of 1.4 μm. The average loss is 0.19 dB/km at 1.55 μm. The total loss of a 216 km-long cable link consisting of 2 km-long fibres with 107 splices was 46.3 dB. The cables also show a good loss stability at 1.55 μm in long-term use.
