DOI: 10.1109/lpt.2019.2946497
Abstract: We demonstrate (in real-time) electrical dispersion compensation in direct detection links using analog transmit side filtering techniques. By this means, we extend the fiber reach using a low complexity solution while avoiding digital preprocessing and… read more here.
