Class Information
Number: 398/147
Name: Optical communications > Transmitter and receiver system > Including optical waveguide > Dispersion compensation
Description: Subject matter comprises means for cor recting or reducing distortion induced by (a) scattering in a light beam as it travels along the fiber or (b) overlapping of a light signal on one wavelength to different wavelengths because of reflected ray and different refractive index of fiber material.
