Alcatel-Lucent 7330 ISAM FTTN
The good news is that FTTN economically increases the
available bandwidth to the subscriber while leveraging the
existing copper plant to keep costs down.
Technological Hurdles
The existing DSL network was engineered to provide
HSI access with down stream bandwidth between 0.5
and 2 Mb/s. Competition and increasing usage of the
broadband connection have driven HSI bandwidth
requirements into the 3 to 8 Mb/s range. However, the
deployment of IPTV service calls for a deep-fiber solution
in the access network. Bandwidth requirements for a
competitive triple play service require 20 Mb/s or more.
