Abstract
A method and apparatus is provided for transmitting an optical signal through an optical fiber. The apparatus includes an optical signal source, which generates an optical signal having a plurality of optical channels onto which data is modulated. Each of the optical channels is defined by a different carrier wavelength. A phase modulator imparts phase modulation to the plurality of optical channels so that channels nearest a zero dispersion wavelength of the optical fiber are more closely spaced to one another than channels farthest in wavelength from the zero dispersion wavelength of the optical fiber.
