Abstract

The combination of broadband optical access and core networks is considered to be one of the most promising solutions for end-to-end transportation of high bit-rate data, video, and voice signals across optical networks of the future. Optical label switching technology (OLS) is an important aspect of optical packet switching and it involves the extraction and processing of the labels so that the packets can be routed to their destinations. OLS enables the routing and forwarding of the ultra-high bit rate payloads from source to destination entirely in the optical domain, thus alleviating the need for expensive optical-to-electrical conversions for processing. We have developed key enabling technologies for merged core and access networks including optical label generation, label swapping, optical buffering, clock recovery and wavelength conversion. We have experimentally demonstrated that these enabling techniques that can provide efficient broadband services in the future access and core networks.
