Al-Optical 2R Regeneration of 40-Gb/s Signal Impaired by Intrachannel Four-Wave Mixing
IEEE PHOTONICS TECHNOLOGY LETTERS, VOL. 15, NO.2, FEBRUARY 2003,-0001,():
Abstract-We experimentally investigate the ability of an alloptical 2R regenerator to suppress impairments caused by intrachannel four-wave mixing (IFWM) and intrachannel cross-phase modulation (IXPM), which are the two dominant nonlinear effects in 40-Gb/s pseudolinear transmission systems. The 2R regenerator suppresses amplitude fluctuations and shadow pulses induced by IFWM in 80-kmansmission over standard single-mode fiber, allowing an increase of signal power by 3dB. However, theregenerator shows little improvement for an 80-km TrueWave RS fiber, where timing jitter originating from IXPM dominates.
