Abstract
An optical transmission system is provided. The system includes a series of consecutive blocks of optical fiber. Each block of the system includes a first, second and third series of spans of optical fiber, where the second series of spans compensates for accumulated dispersion in the first and third series in the wavelength range of transmission. Optionally either the first or third series can be omitted.
