Understand the Principles and Capabilities of Optical Line Systems.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c44878) has announced the addition of E-Learning Course: Optical Line Systems inc. WDM (1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. to their offering. "Optical Line Systems" introduces the principles of optical fibre and describes the capabilities, components and operation of the optical links that interconnect the nodes of a SDH-based broadband network. Course aim: After completing this course a trainee will be able to describe the characteristics, operation and use of the main functional components of optical line systems conforming to the ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. recommendations relating to relating to relate prep → concernant relating to relate prep → bezüglich +gen, mit Bezug auf +acc the Synchronous Digital Hierarchy (communications, standard) Synchronous Digital Hierarchy - (SDH) An international digital telecommunications network hierarchy which standardises transmission around the bit rate of 51.84 megabits per second, which is also called STS-1. (SDH (Synchronous Digital Hierarchy) The European counterpart to SONET. See SONET. SDH - Synchronous Digital Hierarchy ). Pre-requisites: Understanding of the basic principles of synchronous transmission The transmission of data in which both stations are synchronized. Codes are sent from the transmitting station to the receiving station to establish the synchronization, and data is then transmitted in continuous streams. and the principles of the SDH. It is recommended that SyncNet course A: "Transmission principles" and SyncNet course B: "Principles of SDH" is studied before attempting this course. "Optical Line Systems" forms part of the SyncNet suite of courses. SyncNet * is a suite of interactive, multimedia e-learning courses designed to run under Windows[TM] 98, 2000 Professional or XP. * provides training in the technical aspects of SDH-based broadband networks  This article or section needs copy editing for grammar, style, cohesion, tone and/or spelling.You can assist by [ editing it] now. . * consists of six separate but integrated courses: A Transmission principles B SDH principles C Optical line systems inc WDM D SDH payloads E SDH networks F SDH network management and maintenance Each SyncNet course: * provides several hours of in-depth, authoritative technical training * employs interactive simulations, hypertext links and question sessions to fully involve the trainee in the learning experience. * provides personalised training with each trainee able to make his/her on notes and place bookmarks. A record of progress and level of achievement is recorded for each trainee. * provides a structured assessed course and can also be used to browse for revision or reference. * can be studied in isolation or as an integrated suite; each chapter of a course includes revision links to relevant subjects covered in the other SyncNet courses. SyncNet is designed for: * Those studying for a career in telecommunications and who require a detailed knowledge of modern optical broadband transmission networks. * Technical staff involved in the operation, installation or maintenance of SDH-based broadband networks. Course Content: Optical fibre principles: Overview of the electromagnetic spectrum electromagnetic spectrum Total range of frequencies or wavelengths of electromagnetic radiation. The spectrum ranges from waves of long wavelength (low frequency) to those of short wavelength (high frequency); it comprises, in order of increasing frequency (or decreasing advantages of using infrared energy to carry digital information over an optical fibre basic structure of an optical fibre definition and significance of acceptance angle properties of optical sources that are suitable for use in optical transmission systems.

Also known as "wide WDM," CWDM transmits fewer channels and uses wider spacing between the channels for distances up to 60 km. Wider spacing up to 25 nm, compared to 1. ) and Dense WDM (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM.
