In this series, CS1012-A and CS1013-A are suitable for light source coupled single-mode output within the 580nm-850nm visible band. CS1015-A and other optical fibres designed for the 980/1,060nm wavelength exhibit excellent tapering performance. CS1011-A and CS1011-B are specially developed for tapered components in the 1,310 nm wavelength, while CS1018-A and CS1018-B are specially developed for tapered components in the 1,550 nm wavelength. The macro-bending performance of CS1018-A is better than that of G657A2.
