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. 110 Channel Transmitter Part Numbers Description Part Number (SC/APC Optical Connector) Part Number (FC/APC Optical Connector 1RU Transmitter, +6 dBm Optical Output Power 2804TH-SCSP/06 2804TH-SCAP/06 1RU Transmitter, +8 dBm Optical Output Power 2804TH-SCSP/08 2804TH-SCAP/08 Excellent for Medium to Large Campus Video Distribrution Systems. 1RU Transmitter, +10 dBm Optical Output Power 2804TJ-SCSP/10 2804TJ-SCAP/10 +13 dBm Optical Output Power Supports Links beyond 20 km. 1RU Transmitter, +12 dBm Optical Output Power 2804TK-SCSP/12 2804TK-SCAP/12 1RU Transmitter, +13 dBm Optical Output Power 2804TL-SCSP/13 2804TL-SCAP/13 Key Lock Power Switch Prevents Accidental Power-Down.
