We prove that the phase estimation process makes coherent QPSK more vulnerable than DQPSK to the XPM induced by 10G-OOK channels. A novel sensitivity penalty formula is presented and verified against simulations.

Abstract
We prove that the phase estimation process makes coherent QPSK more vulnerable than DQPSK to the XPM induced by 10G-OOK channels. A novel sensitivity penalty formula is presented and verified against simulations.File in questo prodotto:
