Title: IMPROVEMENT OF THE HFC SYSTEM REVERSE PATH PERFORMANCE
Keywords: CATV, reverse path channel, noise, intermodulation distortion, penetrating interference, funnel effect

Abstract: The paper deals with what causes the signal parameters in the reverse path channel of hybrid fiber-coaxial CATV system to worsen. Besides the analysis, a mathematical model of the channel is also suggested with the funnel effect being taken into consideration. If the carrier-to-noise ratio at the receiver input of the headend is known then the model makes it possible to optimize the topology of the coaxial distribution network and the number of optical nodes whose signals are summarized in the receiver. Experimental and analytical results are shown that enable the engineer to determine
