Abstract
To compensate the decrease in its revenue, most telecom operators have adopted similar strategy which is to provide faster Internet with low cost to its customers. Studies suggested that providing faster Internet with low cost can be achieved by reducing the cost of building next-generation access network. Among the various technologies introduced for next-generation access, long-reach optical access LROA is considered the largest candidate. This is due to the anticipated cost effectiveness of this technology. In LROA, more users can be supported over a common optical component (e.g., a transmitter, a fiber, or probably both), i.e., small number of entities is employed in the access network for service provisioning, which is considered as an improvement in the cost-sharing concept. Our objective in this paper is to verify the cost-effectiveness of this technology. To this end, a statistical-based cost comparison was conducted. The comparison was between the currently deployed passive optical networks (PONs), i.e., the Broad band PON (B-PON [G. 983]), the Ethernet PON (E-PON [IEEE802.3ah]), and the gigabit PON (G-PON [ITU-T G. 984]) and one of the LROA architectures proposed in the literature. The comparison process confirmed that the LROA requires less cost and cost per subscriber as compared with the currently deployed PONs.
