CATV
Broadband LANs
Distance Learning
Multiple Data Services
The 2805 79 Channel CATV PNS transmitter is part of a robust system for transporting up
to 79 Channels of VSB/AM modulated signals over a singlemode optical fiber. The system
provides 40-870 MHz of usable bandwidth for video signals stacked at 6 MHz intervals. A
low loss singlemode fiber allows full channel loading to beyond 20 km while maintaining a
good carrier-to-noise ratio. The 2805 may be used with the 2807 mini-node receiver for use
in return path and multiple splitter applications or with the 2808 receiver for basic
79 channel CATV transmission. In all cases, the link provides excellent performance for
many demanding applications such as broadband LANs, distance learning, and multiple
data services.
