Broadband Access Network: Enabling Technologies for Advanced Communication Services

摘要

The uptake of broadband services among residential and small-to-medium-sized businesses is being helped by developments designed to relieve capacity bottlenecks in existing access networks. The functionality, scalability and widespread understanding of Ethernet technology make Ethernet access the strongest candidate to deliver advanced services including IP-based television, IP telephony, and robust, secure, LAN-interconnect services. Fibre offers the most attractive solution, but it must be mentioned that Ethernet copper access can be positioned as a good alternative for the near future, even if the continuously falling costs of laser equipment, fibre and cable installation are making, more than ever, optical fibre access feasible. The Ericsson vision is Ethernet fibre access as a real broadband access enabler to both residential and business users, a single technology end-to-end, and limitless broadband applications and services.
