Abstract: A method includes modulating a digital signal via pulse amplitude modulation (PAM) and applying Nyquist shaping to the digital signal to generate a filtered digital signal. The method also includes converting the filtered digital signal into an analog signal and transmitting the analog signal in an optical communication channel via a dense wavelength division multiplexing (DWDM) scheme.

Abstract: A method includes applying, to a modulated digital signal, a forward error correction (FEC) including a low-density parity-check (LDPC) to produce a coded digital signal. Nyquist shaping is applied to the coded digital signal to generate a filtered digital signal. A representation of the filtered digital signal is transmitted in an optical communication channel via a dense wavelength division multiplexing (DWDM) scheme.
