Abstract :
100-Gb/s-class high-speed transmission technologies are essential to realize future 100 G Ethernet transmission over wide area networks. Optical OFDM (Orthogonal Frequency Division Multiplexing) is promising for high-speed transmission because of its narrow bandwidth and superior tolerance to chromatic dispersion and polarization mode dispersion. In this paper, we show numerically that the nonlinear tolerance of optical OFDM increases as the subcarriers is decreased and describe novel electro-optic subcarrier multiplexing scheme to generate an over 100 Gb/s high speed optical OFDM signal with a small number of subcarriers. We successfully generate a 100 G-class optical OFDM signal and demonstrate transmission over 80-km of ITU-T G.652 single-mode fiber without dispersion compensation.
