Applications
FIBER OPTICS
The 2806 79 Channel CATV LDS transmitter is part of a low cost system for transporting up
to 79 channels of VSB/AM modulated signals over a singlemode optical fiber. The system
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 10 km while maintaining a
good carrier-to-noise ratio. Because of its relatively small size, the 2806 can be mounted
almost anywhere and it is a true plug-and-play system when used with 2808 or 2809
receivers. Together, this link provides excellent performance for many demanding
applications such as broadband LANs, distance learning, and multiple data services.
