We propose a novel hybrid wavelength-division-multiplexed (WDM)/ time-division-multiplexed (TDM) passive optical network (PON) architecture for next-generation optical access networks. This PON is based on a novel virtual PON (VPON) mechanism that will allow wavelength channels to be flexibly allocated to specific ONUs in a dynamic fashion. Dynamic wavelength allocation (DWA) algorithms and dynamic...
The paper presents a service-oriented optical Ethernet network design, which is based on a proposed integrated optical Ethernet network architecture. Through the introduction of a service plane, the service-oriented network enables various service compositions and is able to support carrier grade Ethernet transport services. The paper describes the design and implementation of an IMS based service...
We investigate 10-Gb/s uncooled, directly modulated free-running 1.55-mum VCSEL transmission for WDM-PONs. Wavelength variation with bias current and dispersion tolerance are evaluated for WDM-PON transmission. Errorfree transmission over 10-km SMF and 80-km SMF+DCF have been demonstrated.
