FTTN Leverages the Existing

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 infrastruc ture 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, mini mized operating expenditures (OPEX), less training requirements,
and faster time-to-market for new services.
