G02B6/02252 - 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 Negative dispersion fibres at 1550 nm

Sub-classes:

G02B6/02257 » {Non-zero dispersion shifted fibres, i.e. having a small negative dispersion at 1550 nm, e.g. ITU-T G.655 dispersion between - 1.0 to - 10 ps/nm.km for avoiding nonlinear effects} 17
G02B6/02261 » {Dispersion compensating fibres, i.e. for compensating positive dispersion of other fibres} 63
