INFLUENCING OF THE RECEIVER SENSITIVITY ON THE FIBER OPTIC TRANSMISSION SYSTEMS WDM CAPACITY

Abstract

The change of sensitiveness of the receiving devices in fiber optic transmission systems (FOTS) transition from the SDH technology to WDM and, as a result, change of quantitative estimation of size of possible quantity of spectral channels is considered. Numeral estimations of the maximally attainable quantity spectral channels depending on the level of transmission, sensitiveness of receiving and number of amplifying path on the section of the WDM FOTS regeneration distance resulted.
