Next generation hybrid wireless-optical access with TWDM-PON

This paper reviews the latest progress in ITU-T standards on high-speed access networks. We focus on the employment of the time and wavelength division multiplexed passive optical network (TWDM-PON) for the next generation wireline and wireless broadband services. Several applications with TWDM-PON are proposed. We investigate the proposal by developing a prototype system to test the physical layer capability and network service provisioning. Test results demonstrate salient features of employing TWDM-PON to provide broadband access for residential, business, wireless backhaul and fronthaul.
