FIBER OPTICS
The 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 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 2804 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 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.
