Latest Patents

David W Park holds a patent for "Optical performance monitoring for D/WDM networks." This performance monitoring method is designed for optically amplified transmission systems. It provides the optical power at each amplifier site while considering inaccuracies introduced by stimulated Raman scattering (SRS) in power estimation. The method utilizes an optical spectrum analyzer at the output of the transmission link to accurately measure the output power of each wavelength. This measured value is then sent upstream to the last amplifier in the link to compute an error term, which is the difference between the actual measurement and the estimation. The error term helps infer the SRS-induced error by system elements not accounted for in the model. Subsequently, this error term is fed back to each amplifier in the link, allowing for adjustments in the estimated power to account for SRS-induced inaccuracies.
