Display and Other Indicator LED’s that
Allow Critical System parameters to be
Accurately Monitored.
An Intergral -20 dB RF Test Port
Simplifies Installation, Commissioning,
and Troubleshooting.
Key Lock Power Switch Prevents
Accidental Power-Down.
Multiple Laser Output Power Options
Provide Complete System Design
Flexibility.
Excellent for Medium to Large Campus
Video Distribrution Systems.
+13 dBm Optical Output Power Supports
Links beyond 20 km.
The Model 2804 110 Channel CATV PDS 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 is also suitable for transporting 80 CATV channels along with 30 digital
QAM channels in the upper frequency range. The Model 2804 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.
A key power lock ensures the transmitter cannot be accidentally turned off and a blue 7-
segment display allows the user to monitor a number of system parameters. A -20 dB RF
test port on the front panel provides a convenient means for installing, commissioning, and
troubleshooting the transmitter. The Model 2804 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.
