IRE-Polus LTD is the founder and one of the basic companies of the scientific and technical group IPG Photonics Corporation with production facilities and research centers in Russia, Germany, the USA, Italy. On the communication services market, IRE-Polus LTD presents the HORIZON Optical Transport Platform with wavelength division multiplexing for data transmission at a distance of 6,000 km and more. The company's portfolio includes unique solutions based on erbium and Raman-pumped amplifiers for building single-span lines over 500 km long. The use of multilevel optical modulation formats in tandem with coherent technology makes it possible to organize the maximum traffic transmission capacity — up to 30 Tbit/s per optical fiber when using 600 Gbit/s channels. The properties of versatility and modularity inherent in the solutions of the HORIZON platform make it possible to build systems with any topology / architecture, including those using ROADM and OTN-XC technology. Cross-connect OTN system, DWDM terminal node, traffic dump intermediate node use the same nomenclature of unified cards, which together simplify the construction and operation of the network.
