MC2.1 - NONLINEARITY MITIGATION WITH ADAPTIVE FILTERS
Abstract
Abstract
In this work nonlinear noise caused by interfering WDM channels is discussed. Two adaptive filter techniques are reviewed, fast LMS and generalized filters. Both their individual and combined performance is shown over trans-oceanic transmission distances.
MC2.2 - HYBRID FIBER LINKS USING QUASI-SINGLE-MODE FIBERS
Abstract
Abstract
We compute the optimized fiber splitting ratio of hybrid spans composed of quasi-single-mode (QSM) fibers and single mode fibers using numerical simulations. We show that the optimum ratio increases with the span length, the fiber effective area, and the residual of multipath interference at receiver.
MC2.3 - JOINT LOW-COMPLEXITY OPTO-ELECTRONIC CHROMATIC DISPERSION COMPENSATION FOR SHORT-REACH TRANSMISSION
Abstract
Abstract
A low complexity solution to mitigate chromatic dispersion is proposed for short-reach communications. The technique relies on sharing complexity between optical and electronic domain and shows gains in terms of required receiver SNR for up to 20-km fiber transmission.
MC2.4 - TECHNIQUES FOR OPTICAL PARAMETRIC AMPLIFICATION USING HIGHLY NONLINEAR FIBER
Abstract
Abstract
We review parametric techniques for wideband amplification. Dispersion stable highly nonlinear fibers show operation bandwidth up to 50nm thanks to longitudinal dispersion stability and forth order dispersion close to zero. Quasi phase matching brings flat 20 dB gain by only 1 W order pump power.
