Abstract
A transmitter () for transmitting reverse optical signals in a broadband communications system () that includes a converter () for digitizing the analog RF signals and a carrier-detect circuit () coupled to the converter () for detecting when digital RF signals are present at the output of the converter (). When the carrier-detect circuit () detects digital RF signals, the carrier-detect circuit () allows the digital RF signals to be transmitted upstream through the broadband communications system (). A digital network () then combines the received digital RF signals with other digital RF signals from additional transmitters (). The combined digital signals are then provided to a receiver () that includes a converter () for returning the digital RF signals to analog RF signals and then providing the analog signals to a headend for further processing.
