Abstract
This paper describes a fiber-optic transmission system for access networks with frequency division of channels formed in optical, microwave, and radio frequency ranges. The single-band optical modulation and different formats of modulation of subcarrier channels are studied. The calculated expressions for estimating the number of spectral and subcarrier channels in view of the effect of stimulated Raman scattering (Raman effect) and optical preamplifier noise are presented
