Correlation Between Peak-to-Average Power Ratio and Four-Wave Mixing in Optical OFDM Systems

Abstract

Coherent optical orthogonal frequency-division multiplexed (OFDM) systems have been shown to be vulnerable to fiber nonlinearity, four-wave mixing (FWM) in particular. Consequently, transmission of OFDM symbols with a low peak-to-average power ratio (PAR) is widely recommended. In this paper, we examine the correlation between PAR and the intensity of light… (More)
