Suppression of XPM Penalty on 40-Gb/s DQPSK Resulting from 10-Gb/s OOK Channels by Dispersion Management
01 January 2008
We analytically study the cross-phase-modulation (XPM) impact on 40-Gb/s DQPSK from 10Gb/s OOK channels, revealing it dependence on dispersion map and channel plan, and showing the suppression of the XPM-induced penalty via proper dispersion management.
