Abstract--We show, using simulations, that a combination of
orthogonal frequency division multiplexing (OFDM) and op-
tical single sideband modulation can be used to compensate
for chromatic dispersion in ultralong-haul wavelength-division
multiplexed (WDM) systems. OFDM provides a high spectral effi-
ciency, does not require a reverse feedback path for compensation,
and has a better sensitivity than nonreturn to zero. This paper pro-
vides design rules for 8004000-km optical-OFDM systems. The
effects of WDM channel number and spacing, fiber dispersion,
and input power per channel on the received Q are studied using
extensive numerical simulations. These effects are summarized as
a set of design rules.
Index Terms--Compensation, fiber dispersion, fiber nonlinear-
ity, four-wave mixing (FWM), long haul, optical single sideband
modulation (OSSB), orthogonal frequency division multiplexing
(OFDM).
