Scientific-Atlanta
has unveiled its new Prisma II Targetted Service Delivery
(TSD) Transmitter, designed to make more bandwidth available
per subscriber, cost effectively. According to an official
release, in order to widely deploy interactive services
to their digital cable subscribers, cable operators are
focused on bandwidth utilisation and cost.
With
more subscribers signing up for VoD interactive services,
cable operators are faced with a need to dedicate more bandwidth
per subscriber, reducing the number of homes sharing the
same optical transmission over the last mile of the Hybrid
Fiber Coax (HFC) network. Scientific-Atlanta claims that
its new Prisma II TSD Transmitter addresses that problem
by enabling cable operators to cost-effectively dedicate
a transmitter per node, which delivers three times the bandwidth
normally available. Targetted bandwidth allows cable operators
to offer more individualised interactive TV services, which
will result in lower churn.
Scientific-Atlanta's
TSD transmitter is offered in 3 and 5 dBm optical output
powers that enable a 1:1 ratio of transmitters to nodes
in most network applications. That means more bandwidth
per subscriber at the same cost as traditional HFC networks.
The TSD transmitter is designed for use with Scientific-Atlanta's
new Prisma II High Density Chassis, which solves the space
problem faced by many cable operators in their hub facilities
as they add on new interactive TVservices. Based upon the
Scientific-Atlanta carrier class Prisma II optical transmission
platform, this Chassis supports up to 22 optical transmitters
in a 6 RU rack space.
