Abstract
A method for determining interactions between a number of optical channels in a wavelength division multiplexed signal wherein, given that during broadband optical transmission, the quality of a “Dense Wavelength Division Multiplexed” signal is adversely affected by multiple channel interactions, the method is used to determine the governing effects, the Kerr effect and the non-linear scattering process by evaluating the spectral profile of the Q factor or of the bit error rate.
Claims10
A method for determining interactions between a number of optical channels in a wavelength division multiplexed signal, the optical channels including both boundary channels and central channels, the method comprising the steps of:
- determining quality parameters for all the optical channels;
- determining a spectral profile of the quality parameters;
- and
- evaluating the spectral profile of the quality parameters to distinguish between a Kerr effect and a non-linear scattering process as a reason for the interactions.
