Transmits up to 110 channels overone single-mode fiber.
VSB/AM transmission ensurescompatibility with standard CATVmodulators, processors, etc.
The transmitter includes a 7-segment LED andother indicator LEDs that allow critical systemparameters to be accurately monitored.
An integral -20 dB RF test point simplifiesinstallation, commissioning, and troubleshooting.
Excellent for medium to large campus videodistribution systems.
Multiple laser output poweroptions provide complete systemdesign flexibility.
Key lock power switch prevents accidentalpower-down.
The Force CATV Model 2804 110 Channel CATV Professional Distribution System (PDS) transmitter is part of a robust systemfor transferring up to 110 channels of VSB/AM modulated signals over a single-mode optical fiber. The system is also suitablefor transferring 80 CATV channels along with 30 digital QAM channels in the upper frequency range. The Model 2804 provides40-870 MHz of usable bandwidth for video signals stacked at 6 MHz intervals. A low loss single-mode fiber allows full channelloading to beyond 20 km while maintaining a good carrier-to-noise ratio. A key power lock ensures the transmitter cannot beaccidentally turned off, and a blue 7-segment LED readout allows the user to monitor a number of system parameters. A -20dB RF test point on the front panel provides a convenient avenue for installing, commissioning, and troubleshooting thetransmitter. The Model 2804 may be used with the Model 2807 mini-node receiver for use in return path and multiple splitterapplications or with the Model 2808 receiver for basic 110 channel CATV transmission. In all cases, the link provides excellentperformance for many demanding applications such as broadband LANs, distance learning, and multiple data services.
