Rayleigh Noise Mitigation in Channel-reuse 10Gb/s/λ DWDM-PON Employing Optical Beat Noise-based Self Wavelength Managed Tunable Laser

Abstract

We propose an optical beat noise-based wavelength difference detection method and a RB noise mitigation method relying on wavelength shift between upstream and downstream used in tunable laser-based channel-reuse DWDM-PON system. The feasibility is also experimentally verified.
