Cisco Multimedia Line Equalizer Reverse Conditioner 870 MHz - 42 51 Split Data Sheet
Description
The Multimedia Line Equalizer/Reverse Conditioner
(LEQ/RC) is a by-product of the extensive reverse path
studies that Scientific-Atlanta has been conducting. This
analysis has conclusively determined that, by strategically
attenuating the reverse path signals, systems are able to
better support transmission in the challenging portion of the
spectrum.
This reverse path attenuation has several key benefits. First,
it raises the output levels of communicating devices (e.g.,
home communications terminals, cable modems and cable
telephone NIUs) to the upper ends of their dynamic ranges,
thereby increasing overall signal-to-noise performance.
Second, by lowering their dynamic range variance,
deployment of new services is simplified. Third, the additional
reverse attenuation minimizes concerns about overdriving
optical return transmitter lasers.
