FTTN Leverages the Existing
Copper Infrastructure
For many customers, the long-term solution is to deploy fiber-to-the-user (FTTU). This will enable the delivery of virtually unlimited subscriber bandwidth. While this solution is available today and practical in many cases, time-to-market and short-term economic pressures are driving a more incremental access strategy — FTTN. As illustrated in Figure, 1, by leveraging the existing copper infrastructure and by deploying fiber deep in the outside plant, FTTN reduces copper loop lengths, cuts trench costs, and increases bandwidth with DSL.
As a member of the ISAM family, the Alcatel-Lucent 7330 ISAM FTTN delivers a full suite of triple-play services to all customers regardless of the population density and central office (CO) reach. Designed to be flexible and standards-based, the Alcatel-Lucent 7330 ISAM FTTN assures simplified oper- ations, minimized operating expenditures (OPEX), less training requirements, and faster time-to-market for new services.
