EMCORE 2804TK

Model 2804
110 Channel CATV Professional Distribution System (PDS)
DATASHEET | JANUARY 2012
Features
Transmits up to 110 Channels Over One
Singlemode Fiber at 1310 nm.
VSB/AM Transmission Ensures
Compatibility with Standard CATV
Modulators, Processors, etc.
The Transmitter Includes a 7-Segment
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.
FIBER OPTICS
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 7segment 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 mininode 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.
