Warning
The optical emissions from the chassis and connected optical fiber are laser-based and may present eye haz-
ards. Follow all safety precautions

Model 2804 Professional Distribution Solution (PDS) 110 Channel Transmitter User Manual Product Specifications Optical and Video Characteristics: @ 25 °C, SM Fiber (Note 1) Min. Typ. Max. Units Notes Channel Loading Bandwidth Operating Wavelength 1290 1310 1330 Optical Output Power (P/N ends in /06) - Page 4 Specification Notes 1) The Model 2804 has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
- Page 5 4) Be sure to compute your fiber bandwidth (end-to-end) as well as attenuation. The Model 2804 incorporates an optical isolator in the laser package that reduces the effect of optical backreflections on the laser performance. However, all analog lasers are affected by optical backreflec- tions.
- Page 6 Model 2804 Professional Distribution Solution (PDS) 110 Channel Transmitter User Manual 5) Figure Figure 3 presents a tremendous amount of performance data for the 2804 link. The horizontal axis is the amount of optical light that reaches the receiver. (It is not the loss between the transmitter and receiver.) The vertical axis shows the carrier-to-noise ratio at a given optical input level.
- Page 7 Figure 5 Transmitter Level/Channel vs. Log (Number of Channels) Figure Figure 6 shows the response of the Model 2804 transmitter’s integral RF power meter. This meter is accessed via pin 5 of the 9-pin D-sub connector on the rear of the transmitter.
- Page 8 Model 2804 Professional Distribution Solution (PDS) 110 Channel Transmitter User Manual Figure 6 Response of Model 2804 RF Power Meter 7) Each transmitter has a label such as the one shown in Figure 7 that gives the RF input levels for the trans- mitter.
- Page 9 Model 2804 Professional Distribution Solution (PDS) 110 Channel Transmitter User Manual 9) Fuse Rating is 1.25A, Slow-Blow. CAUTION Risk of fire. Only use fuses with same type and rating as marked. 10) Most parameters are relatively unaffected by varying temperature. A moving air environment is recom- mended at ambient temperatures above +35°C.

See page iii for Force’s standard war- ranty. WARNING OPTICAL LASER RADIATION IS PRESENT AT THE TRANSMIT- TER’S CONNECTOR WHEN THE UNIT IS TURNED ON.
- Page 13 Ideally, the RF level should be checked with an instrument such as a spectrum analyzer to verify that the levels are appropriate. If instrumentation is not available to actually measure the RF levels, Force recommends add- ing 40 dB of attenuation at the transmitter input; 40 dB of attenuation will adequately protect the unit from the highest RF levels that might be seen in a typical CATV installation.
- Page 14 For Model 2807: The power supply must be from +12 to +16 Volts DC. It is critical that the supply voltage never drops below +12 Volts. If the voltage drops below +12 Volts, the link may not operate. Force, Inc.
- Page 15 3) The RF input spectrum may not be flat. It is possible to have a green RF Level LED even if the input spec- trum has a large amount of tilt. All Force CATV products are designed to operate with a flat input spec- trum.
