Methods and systems to mitigate the degradation of the optical signal-to-noise ratio of optical networks

Title:

Methods and systems to mitigate the degradation of the optical signal-to-noise ratio of optical networks

Document Type and Number:

Japanese Patent JP6330470

Kind Code:

B2

Abstract:

Methods and systems for mitigating degradation of an optical signal-to-noise ratio (OSNR) induced by polarization dependent loss (PDL) in an optical network include determining an increase in power (ΔP) corresponding to a PDL-induced decrease in OSNR for a given channel being transmitted over an optical signal transmission path. The increase in power (ΔP) may be adjusted for at least some of the network nodes in the optical signal transmission path. At certain network nodes, the increase in power (ΔP) may be realized with a combination of attenuation and gain.
