Estimating the number of spectral and subcarrier channels in fiber-optic access networks with single side band optical modulation

Abstract

This paper describes a fiber-optic transmission system for access networks with frequency division of channels formed in optical, microwave, and radio-frequency bands. The single side band optical modulation and different modulation formats of subcarrier channels are studied. The estimated relationships for estimating the number of spectral and subcarrier channels are given with account for the effect of stimulated Raman scattering and optical preamplifier noise.
