| Abstract: | An optical-fibre unit with a strain-relaxing effect is proposed for realising a highly reliable optical-fibre submarine cable. The basic design of the new type of optical-fibre unit means that optical fibres are not subjected to the same strain as the fibre unit directly when the unit is elongated. The test result of the strain-relaxing effect of an experimental optical-fibre unit was about 0.2%, and optical fibres returned to the original position in the fibre unit after the tension was released. |
