Optical links of data transmission in city areas

Abstract

Modernly produced optical links of data transmission, which are working in an opened waether area on infrared waves, are used as links of data transmission in cities. Optolines are used for fast construction of connections on distances ranging from tens of meters to several kilometers. They are used to transmit bit rates of 2Mbit/s or n*2Mbit/s. The article presents the operational estimate of usefulness of the optoline working on waves of X = 0,86 - 0,92/im spectral range. Despite low estimates of the product a new prospect appears before it. New technologies enable optolines to work on waves of X = 9 - 12pm spectral range and are the future for evolution of that practical device. The article also speaks of expectations in the subject of transmission parameters.
