Electronic precompensation of intrachannel nonlinearities at 40 gb/s

Electronic precompensation of intrachannel nonlinearities at 40 gb/s

Digital electronic precompensation of intrachannel nonlinearities is studied in a transmission system which consists of 100% dispersion-compensated spans. Different Mach-Zehnder-based transmitter structures are compared. Simulation results demonstrate that using a triple Mach-Zehnder modulator achie...

Zusammenfassung:Digital electronic precompensation of intrachannel nonlinearities is studied in a transmission system which consists of 100% dispersion-compensated spans. Different Mach-Zehnder-based transmitter structures are compared. Simulation results demonstrate that using a triple Mach-Zehnder modulator achieves effective compensation of intrachannel nonlinear effects at large launch powers
