Transmits up to 110 channels over
one single-mode fiber.
VSB/AM transmission ensures
compatibility with standard CATV
modulators, processors, etc.
The transmitter includes a 7-segment LED and
other indicator LEDs that allow critical system
parameters to be accurately monitored.
An integral -20 dB RF test point simplifies
installation, commissioning, and troubleshooting.
Excellent for medium to large campus video
distribution systems.
Multiple laser output power
options provide complete system
design flexibility.
Key lock power switch prevents accidental
power-down.
The Force CATV Model 2804 110 Channel CATV Professional Distribution System (PDS) transmitter is part of a robust system
for transferring up to 110 channels of VSB/AM modulated signals over a single-mode optical fiber. The system is also suitable
for transferring 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 single-mode 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 LED readout allows the user to monitor a number of system parameters. A -20
dB RF test point on the front panel provides a convenient avenue 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.
