Abstract

The effectiveness of colorless performance- improved wavelength-division-multiplexing passive optical networks (PONs) compatible with gigabit-PON is presented. The proposed solution is based on a service optical network unit (service-ONU) for multiwavelength distribution. Mitigation of Rayleigh backscattering effect and path-loss degradation is demonstrated in 2.5- and 10-Gb/s reflective schemes employing reflective semiconductor-optical- amplifier and reflective electroabsorption modulator at the ONU.
