Abstract
An optical transport system that uses tunable filters to vary the central wavelengths and spectrum widths of channels within the system to more efficiently use the bandwidth of the fiber. Higher bit rate channels may be divided into multiple lower bit rate channels, and lower bit rate channels may be combined to form higher bit rate channels.
