Abstract
A cable television system ( ) for transmitting information in forward and reverse directions includes forward and reverse paths over which information is transmitted and a reverse path transmitter ( ) and a reverse path receiver ( ), both located in the reverse path. The reverse path transmitter ( ) receives an analog electrical signal and an external digital signal from an external source, such as a PCS terminal or router. The transmitter ( ) then generates a single digital bit stream from the external digital signal and the digital electrical signal and transmits the single digital bit stream modulated at a first wavelength over a fiber optic communication medium ( ) that couples the transmitter ( ) and the reverse path receiver ( ). The reverse path receiver ( ) receives and demodulates the single digital bit stream to regenerate the digital electrical signal and the external digital signal, converts the digital electrical signal to the analog electrical signal for processing within the cable television system ( ), and forwards the external digital signal for processing by a second external source outside the cable television system ( ).
