Abstract
Linearization of a high-bandwidth coherent driver module is demonstrated to enable the use of larger swing for driving signals. It is verified for symbol rates and modulation formats up to 80-GBd and 256-QAM, leading up to 3.7-dB higher transmitter output power compared to linear predistortion.
