Abstract
Delivering video
over the 1550nm wavelength has been the backbone for
traditional cable television operators since the first
community antenna networks needed to traverse any
significant terrestrial distance. With the emergence and
growth of fiber-to-the-home (FTTH) networks from
non-traditional video providers, some may reason that this
older delivery system might be abandoned or minimized.
However, this has not been the case. In fact, broadcast
video delivery at 1550nm as an overlay in FTTH networks has
become the new backbone of these modern, fiber optic
networks – resulting in a rebirth of the technology. In
fact, 83 percent of FTTH networks in North America use a
video overlay solution to deliver state-of-the-art video
services. Considering this development, it is important for
service providers to understand how this video delivery
method can be
optimized. This paper presents the Scientific Atlanta view
of the ultimate video overlay solution relative to
operations, technology and cost.
