G02B6/02219 - 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

Sub-classes:

G02B6/02223 » {Dual window fibres, i.e. characterised by dispersion properties around 1550 nm and in at least another wavelength window, e.g. 1310 nm} 11
G02B6/02228 » {Dispersion flattened fibres, i.e. having a low dispersion variation over an extended wavelength range} 4
G02B6/02247 » {Dispersion varying along the longitudinal direction, e.g. dispersion managed fibre} 11
G02B6/02252 » {Negative dispersion fibres at 1550 nm} 11
G02B6/02266 » {Positive dispersion fibres at 1550 nm} 88
G02B6/02276 » {Dispersion shifted fibres, i.e. zero dispersion at 1550 nm} 19
