Studying the Feasibility and Importance of Optical Access Network Strategies in the Information and Communication Environment

The access network has consistently been regarded as a bottleneck in the provisioning of data communication services. This is primarily because the bandwidth available has lagged behind that provided within Local-Area Networks (LANs) and in the upper echelons of the network (in metropolitan and core networks, for example), where concentration factors and economies of scale have allowed optical fiber to unleash significant bandwidth capacity. The optical access network is that part of the access network implemented using optical fiber. Optical access offers the promise of greatly increased access-network bandwidth by up to several GigaBits Per Second (Gbps) - and most likely more, as technology advances.
