More Information
Summary:A cable television system (100) includes forward and reverse paths. In the reverse path, an optical transmitter (405), which could be located in an optical node (115), receives an analog information signal from subscriber equipment (130) and transmits in accordance therewith a digital optical signal. The optical transmitter (405) digitizes its incoming signal, compresses the signal, and generates therefrom the digital optical signal. The cable television system (100) also includes an optical receiver (500) for receiving the digital optical signal, decompressing information included in digital optical signal, and recovering therefrom an analog signal representative of the analog information signal. The optical receiver (500) could be included in a hub or headend equipment (105) of the cable television system (100).
