The Fiber-Optic Communication System in the Enterprise

The article discusses the development of a system that provides more throughput up to 40 Gbit instead of 10 Gbit using the TWDM-PON (Time and Wavelength Division-Multiplexed Passive Optical Network) system, which was chosen by the international companies FSAN (Full-Service Access Network) and the ITU-T (Telecommunication Standardization Sector of the International Telecommunication Union) group. This system uses the time and frequency division of channels. In this article, this system is developed, and its operation is simulated at a distance of 40 km and with data transfer up to 40 Gbit/s. Also, the system was optimized and the optimal bandwidths for the optical and electrical filters were selected, as well as the optical power of the laser, etc.
