A novel Optical Network Units Source-free Scheme using Optical Frequency Comb Generator for OFDM-PON
The letter proposes a novel Optical Network Units (ONUs) source-free scheme for Orthogonal Frequency Division Multiple (OFDM)-based passive optical networks (PON),in which an optical frequency comb generator built by a conventional Mach-Zehnder modulator (MZM) is used to generate ultra-flat optical frequency comb spectra for the downstream and upstream transmission.The proposed architecture is presented and simulated to achieve simultaneously upstream transmission from multiple ONUs over the fiber.Simulation results show the receiver sensitivity reaches-18dBm for upstream transmission and-18.75dBm for downstream transmission.
