Abstract :
Closed form formulae are derived to study crosstalk degradation due to cross-phase modulation (XPM) induced crosstalk in periodically amplified and dispersion compensated fiber links. The formulae are used to evaluate the crosstalk performance of different modulation formats especially differential phase-shift keying (DPSK) and ON?OFF keying (OOK) which are widely used in optical communication. Crosstalk sensitivity for different data rates and pulse shapes prevalent in optical data transmission is also evaluated. The study shows that minimum XPM induced crosstalk can be achieved for 40 Gb/s RZ-DPSK signal with 33.3% duty cycle in WDM system.
