Abstract
100-Gb/s-class high-speed transmission technologies are essential to
realize future 100G 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 100G-class optical OFDM signal and demonstrate transmission over
80-km of ITU-T G.652 single-mode fiber without dispersion
compensation.
