Researches Methods for Increasing the Throughput of Fiber-Optical Communication Networks Based on Optical Spectral Technology

摘要

An analysis of the advantages using the architectural concept of the following NGN (Next Generation Network) and future FN (Future Network) networks to build optical multi-service telecommunication systems based on the technology spectral separation information channels, supporting a wide range multimedia services, was carried out. Efficiency, communication quality and transfer characteristics fiber-optic communication networks using optical means as receiving optical modules (ROM), fiber-optic cables (FOC) and transmitting optical modules (TOM) were investigated. Based on the study, a new approach has been proposed to create methods for calculating the throughput indicators fiber-optic communication networks based on spectral separation technology, which are based on the principles wavelength multiplexing. Based on calculation methods, analytical expressions are obtained to estimate line performance, optical signal-to-noise ratio at the output communication lines and transfer characteristics fibre-optic communication lines using single-mode fiber.
