Ethernet, etc.) Via CATV RF Modem.
CATV HFC Distribution Network,
Distance Learning, CCTV Video
Surveillance, Campus Video Distribution,
Teleconferencing and more.
+13 dBm Optical Output Power Supports
Links to beyond 20 km.
The Model 2805 110 Channel CATV PNS transmitter is part of a robust system for
transporting up to 110 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 Model 2805 may be used with the
Model 2807 mini-node receiver for use in return path and multiple splitter applications or
with the Model 2808 receiver for basic 110 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.
