Anordning och förfarande för dispersionskompensering i ett fiberoptiskt transmissionssystem

摘要

The present invention relates to a device and a method respectively for dispersion compensation in a fibre optic transmission system in which an optic signal is fed to the device. The device comprises an optic separating device for spectral optic splitting of the optic input signal into two branches in an upper and lower modulation sideband, a delay device for selective delay of the spectral bands in relation to one another, and a combining device for combining the sidebands.
