G02B6/02276 - CPC Classification

Classification description:

Light guides; Optical fibres with cladding tailored to obtain the desired dispersion, e.g. dispersion shifted, dispersion flattened; Characterised by the wavelength dispersion properties in the silica low loss window around 1550 nm, i.e. S, C, L and U bands from 1460-1675 nm Dispersion shifted fibres, i.e. zero dispersion at 1550 nm
