Next-generation access networks: A preview

Abstract

the lower operational expenditure (OPEX) associated with operating and maintaining a single network, with typical operator estimates for the magnitude of these savings in OPEX being on the order of $100 per subscriber per year. In addition to the apparent cost savings associated with the transformation to an "all IP" network, the intent was to increase the average revenue per user (ARPU) by offering a full complementThe First Phase of Network Transformation: The Move to "All IP"Over the past few years, the traditional telecom operator's network has undergone a transformation to an "all Internet Protocol (IP)" network, with the amalgam of legacy networks that had been built to provide residential and business voice and data services being replaced by a single packet-based IP/Ethernet and IP/multiprotocol label switching (MPLS) network. One of the main drivers of this transformation was

Gigabit-capable Passive Optical Network in Telecommunication Networks

“…However, the current trend in development of telecommunication networks is shifting toward the new generation network (NGN) [1,2]. In the beginning of optical telecommunications, optical fibers as the transmission medium were used only for long-haul applications (core part from Figure 1), but presently, this medium pretends to cover almost whole telecommunication networks.…”
