Connecting Optical Fibers

The need to connect the optical fiber occurs when the construction of fiber-optic links (FOL), as well as the restoration of optical fibers after the accident. In some cases, welding is used to make some attenuation in optical fibers liniyu.Soedinenie requires very precise alignment, which can be run on the device as the core and shell of the fiber. This is necessary in order the entire light beam passes through the connection with minimal losses. There are two main methods of connecting optical fibers: Welding and mechanical soedinenie.Opticheskaya svarka.Dlya welding fibers applied optical welders. Our company has provided equipment from leading world manufacturers: Fujikura (Japan), Sumitomo (Japan), Furukawa (Japan), Corning (USA), Jilong (China). For detailed information about them can be found in relevant sections of the site splicers.ru. See altavista for more details and insights. The optical connection is welding machines using electrical discharge (arc). This operation can be performed both in automatic and manual rezhime.Pered bonding an optical fiber must be prepared.

To begin, remove the protective cover from the fiber. For this purpose special tools. Then, the fiber must be cleaned from the remnants of the gel. After that produce chipping. Cleavage is necessary to ensure that the welded end of optical fiber has been completely smooth. Cleavage produces a special device, which is called – an optical fiber cleaver. There mass of instruments of this kind. Put together and free from dust and fat with alcohol wipes optical fiber is placed in a welding machine.

And fiber is welded to the selected rezhimom.Tipovoy welding machine consists of two clamps, which fit into the fiber, and two electrodes between which the arc electric discharge. Properly align the fibers and lay about each other built-in microscope and help screen, which displays the welding process. Devices with an arc discharge can weld up to 24 fiber ribbon odnovremenno.Bolshinstvo modern devices for welding optical fibers have automatic modes with the ability to custom programming, which facilitates the welding process. Built-in computer allows you to align the fibers with high accuracy and to choose the right discharge power, which allows us to achieve a high quality connection with the damping of no more than 0.02 optical dB.Sovremennnye welding allow you to make a given attenuation of the line. Loss to 10dB can be programmed with svarke.Mehanicheskie soediniteli.Mehanicheskie connectors allow to dispense with welding equipment. Loss of their use are of 0,5 dB to 0,75 dB. The most frequently used in the budget lines, or as a temporary replacement Welded soedineniyu.Kratky itog.Takim way, thanks to its compact size, versatility, high quality connections, machines for welding optical fibers are now indispensable tools for installation and maintenance of fiber optic.

Library Information Systems STU

The company "Alley Software" took part in the VIII Scientific Conference "Library consortia: technologies and innovation", held from 14 to 20 June 2010, with the support of the St. Petersburg State Polytechnic University and the Association of Regional Library Consortia (ARLICON). The conference brought together over 200 participants, among them – representatives of the university, school, regional, public libraries, IT professionals, experts in education and information services to professionals and vendors of books printed and electronic information products. The priority themes of the conference this year were corporate library and information portals in the era of web 2.0 and web 3.0 as a medium for interaction between librarians and users, the changes in the transition to electronic library resources (technology, digitization, and accounting resources and databases, performance evaluation use.) Considerable attention was paid to the electronic library systems, as well as issues of training and retraining and professional skills Librarian future. Speakers event – managers and employees of the largest libraries of Russia and the CIS – have demonstrated already working solutions for the effective management organization of library resources in modern conditions of solutions, in particular – an integrated information resource "The scientists of the Tomsk Polytechnic University" (NB TPU), network information portal Petersburg studies "Peace of St. Petersburg" and the corporate network portal combined resources of libraries St. Petersburg (TSGPB them. Mayakovsky), a national electronic resource Presidential Library.

BN Yeltsin consolidated portal of electronic card catalog of the Republic of Tatarstan (Institute Library Information Systems STU) and many others. "Our company – the traditional party conference-exhibition ARBIKON." – Said Stanislav Kim, CEO of "Alley of Software" – "This event has always been a platform for professional communication and exchange of experience. But this year we decided to provide an opportunity to keep abreast of events at the conference for those who, for whatever reason do not unable to personally attend to it: first in the library environment conducted on-line broadcast of the conference via Twitter and blog community ELIBCONSULT. This translation does not simply duplicate the presentations of speakers, but contains DISCUSSION – asked the audience questions, answers and comments from experts. The resulting response to the broadcast was very high and this is good news: it means that there is a need and interest in this web 2.0-and communication specialists who are ready to actively seized of the matter. We as a IT company located in constant interaction with professionals of librarianship, was born quite a few ideas for the development of such services, implementation of which will be discussed in the near future.

KabelGmb Product

In the final After all, cable is designed and aimed at mass production, which in diameter is 2.6 mm. When we get the width of the wire of 1.1 mm, it becomes clear what should be a manufacturing tolerance. Insulation and the shell will be wall thickness from 0.35 to 0.4 mm. To ensure that mobility will be used by a special combination of lubricants between conductor and sheath. This is one example of developing a new cable design according to customer requirements. To the Director of TKDKabelGmbH.

TKD Kabel GmbH providing the highest quality manufactured products, carry out tests to verify the mechanical and electrical properties of cables. All companies are certified, ensuring the quality of the process. A list of tests that are conducted during product development is very large. The most basic for this product range is undoubtedly the test that reproduces mechanical stresses and ensures long life outdoors. For this testing is conducted, such as landing loads on multiple bending, drum samples, which stimulated a very high twisting or pulling the load during operation. In addition the products are tested for resistance to aging wires conditioned cabinets.

Bottom line: As far as cable requirements in the transport equipment multifaceted, so versatile test. At the present time in modern high-tech world in solving the problems of lifting, transportation and movement of goods can not do without drag chains. In stock cables for lifting and conveying systems there are cables that are directly targeted or may be used for this application.
