Abstract :
A 10-Gb/s subcarrier multiplexing long-haul optical system is reported. 4/spl times/2.5 Gb/s data streams are combined into one wavelength, which occupies a 20-GHz optical bandwidth. Optical single sideband is used to increase bandwidth efficiency and reduce dispersion penalty. The receiver sensitivity is calculated using a simplified receiver model with an optical preamplifier. The measured results agree well with the analytical prediction.
