WDM transmission system derived from coherent optical OFDM and its performance analysis

Abstract

Abstract: Coherent optical orthogonal frequency division multiplexing transmission has got special attention in numerous studies due to its interesting and efficient transmission performance, wavelength-division multiplexing technology improves system capacity by increasing the number of parallel transmission wavelength in optical fiber, The combination of coherent optical orthogonal frequency division multiplexing and WDM technology in optical fiber communication has been able to build high speed rate, large capacity and low cost for optical transmission networks. In this paper applications of theoretical model and the basic principles of WDM system using coherent optical OFDM are studied. A simulation experiment of 100Gb/s×32-channel WDM transmission system has been derived from the coherent optical OFDM and the transmission performance of the system were studied. The simulation shows that the system Q of the WDM channels at 3.2Tb/s is potentially over 16.0 dB for a transmission up to 1500 km-long standard single mode fiber without any optical dispersion and nonlinear compensation.

Key words: optical communication, coherent optical OFDM, WDM, long-haul transmission
