The CATVLinx Series Force, Incorporated Model 2903 25 Channel VSB/AM Video Link provides a high-quality system for transferring up to 25 video channels over single-mode optical fiber with complete EMI immunity. The unit offers exceptional analog bandwidth from 2 MHz to over 350 MHz allowing transmission of all sub-band channels, low-band channels, FM channels, and mid-band channels. The lowest high-band channels may also be accommodated. The best performance will be achieved when the channel plan is designed to contain all of the channels within a single octave of bandwidth. In conjunction with a VCR, a camcorder, or cable television feed, the Model 2903 can transmit TV channels, along with their sound carriers, over a distance of 50 km or more at 1550 nm, over one single-mode fiber. A basic channel plan for the 25 channel link is TV channels G through I, Channels 7 through 13, and Channels J through AA. Other plans are possible. The carrier-to-noise (CNR) ratio is typically 51 dB at low optical loss. The units also offer exceptional performance at lower channel loadings.
