Abstract
Passive Optical Networks allow more and more homes and enterprises to use optic fiber as the transmission medium for access to High-Speed Internet. These kinds of networks are limited by length and data rate due to distortion, noise, and attenuation when light propagates over optic fiber. In this investigation, a simulation of a 200 Gb/s (4x50 Gb/s) WDM-PON with PAM4 and PAM8 modulation without predistortion is performed; it permits transporting more bits over the same bandwidth, increasing spectral efficiency. A scenario was implemented in Optsim® in co-simulation with Matlab® software, and compare the performance over 50%, 60%, 70% and 100% of the necessary bandwidth photodetector. Data was transmitted over a 20 km link, with dispersion compensation with a G.652D standard single-mode fiber. Results show that using PAM-4 against PAM-8 improves 8 dB for objective BER=10-3 as the maximum value to implement FEC in the receptors.
