Abstract

In the qualification work of the master, the development of a method and means of increasing the accuracy of the data transmission to the reclamation adverting LED panel on the fiber-optic interface of the line based on the optical information communication system were presented. The advanced signal transmission method in the fiber-optic interface allows you to transmit signals with higher stability and reliability was presented. A modified mathematical model of the work of the tool allows to take into account the parameters of signal filtration, at WDM wave multiplexing, and allows to carry out accurate estimates of the effects of negative spectral components for their compensation was developed. Also are considered and modified classification of fiber-optic cables for interfaces, which includes a subclass - special-purpose fiber-optic cables that perform combined data transfer and power supply functions in one cable. The structures of fiber-optic interfaces, which compensate for the impact of negative sectoral components to improve the reliability of the process and extend the functionality capabilities were developed, Its provides the reduce the number of communications, which uses approaches to increase the stability of work when deterioration of background noise, and also provides has a better characterization of the stability of the transmission of information compared with normal communication interfaces. The calculation and development of the means were carried out on the basis of previous results, which simulated and calculated the parameters of the transfer medium and the properties of the passage of radiation through the optical medium of the fiber optic cable were done.
