Abstract

In this paper we analyze analog CATV transmission system where only one wavelength is used for transmission on which multiple analog RF channels modulated. We analyze different modulation distortions such as composite second order (CSO), composite triple beat (CTB) and intermodulation distortions at different frequencies. Good performance of CSO > −36 dBc and CTB > −41 dBc are obtained at 62.5 MHz, 125 MHz and 187.5 MHz in three tone directly modulated CATV transmission system.
