Modernization of the OTS system of the West Siberian railway


Modernization of the OTS system of the West Siberian railway. The technical solution of EZNP RAS and CITES Telecom

The active development of backbone digital communication networks of the Ministry of Railways of Russia on the basis of laid fiber-optic lines and modern equipment for channel formation and transmission creates the necessary prerequisites for the modernization of technological communication systems (OTC and OBTS).

Modernization of communication networks

Restructuring of the control system on w. e-transport based on the use of information technology inevitably requires a fundamental reconstruction of the existing communication network by introducing modern digital transmission systems via optical fibers and optical switching methods. The purpose of this reconstruction is to increase the channel capacity and obtain qualitatively new types and communication services.

Management of optical transport networks.
The basics of managing a fiber optic communication network are described. The architectures of networks that can be used are considered. used in the construction of not only linear optical systems but also more complex ones. Complex operational tests of the network with 2 long-span routers were carried out.

What Are Backlinks?

     Backlinks (also known as “inbound links”, “incoming links” or “one way links”) are links from one website to a page on another website. Google and other major search engines consider backlinks “votes” for a specific page. Pages with a high number of backlinks tend to have high organic search engine rankings. https://plus.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://plus.google.com/url?q=https%3A%2F%2Fwww.honeywebsolutions.com%2F https://plus.google.com/url?q=http%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://www.google.com/url?sa=t&url=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://images.google.de/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.de/u...

The first transatlantic telephone cable to use optical fiber

The first transatlantic telephone cable to use optical fiber was TAT-8, based on Desurvire optimised laser amplification technology. It went into operation in 1988. Third-generation fiber-optic systems operated at 1.55 μm and had losses of about 0.2 dB/km. This development was spurred by the discovery of Indium gallium arsenide and the development of the Indium Gallium Arsenide photodiode by Pearsall. Engineers overcame earlier difficulties with pulse-spreading at that wavelength using conventional InGaAsP semiconductor lasers. Scientists overcame this difficulty by using dispersion-shifted fibers designed to have minimal dispersion at 1.55 μm or by limiting the laser spectrum to a single longitudinal mode. These developments eventually allowed third-generation systems to operate commercially at 2.5 Gbit/s with repeater spacing in excess of 100 km (62 mi). fiber optic technician certification The fourth generation of fiber-optic communication systems used optical amplification to ...

Fiber optic communications Internet

Fiber optic communications Internet The fiber-optic Internet connection service breaks down the greatest limitation of cyberspace: its exasperating slowness. The purpose of the following article is to describe the mechanism of action, advantages and its disadvantages. To navigate the worldwide network of networks, the Internet, not only a computer, a modem and some programs are needed, but also a large dose of patience. The cyberspace is a slow world to despair. A user can spend several minutes waiting for a page to load or several hours trying to download a program from the Network to their PC. This is because the telephone lines, the means used by the majority of the 50 million users to connect to the Internet, were not created to transport videos, graphics, texts and all other elements that travel from one place to another on the Net. But telephone lines are not the only way to cyberspace. Recently a service allows you to connect to the Internet through fiber optics. The o...
