Abstract
Using a Mach-Zehnder modulator, predistorted to third-order only, 77-c hannel CTB's are measured that surpass published theoretical limits, N ew CTB limits for nth-order predistortion are calculated. Modulator an d predistorter bandwidth limitations are shown by numerical simulation to limit the CTB obtainable in practical systems.
