Introduction to the optical communications by simulating an optical high debit transmission chain using optisystem with comparison of optical windows

This article proposes a global study of an optical high debit chain presenting a complete simulation by comparing between the tree optical windows of telecommunications, led as an experience for teaching optical communications which are currently characterized by a grand demand for their exceptional transmission quality offering high debit, long distance of propagation and strong immunity against noise. | International Journal of Computer Networks and Communications Security VOL. 3, NO. 2, FEBRUARY 2015, 53–62 Available online at: www.ijcncs.org E-ISSN 2308-9830 (Online) / ISSN 2410-0595 (Print) Introduction to the Optical Communications by Simulating an Optical High Debit Transmission Chain Using OptiSystem with Comparison of Optical Windows ABDELHAKIM BOUDKHIL1, ASMAA OUZZANI2 and BELABBES SOUDINI3 1, 3 Dept. of Electronics, Faculty of Technology, University of Sidi Bel abbes, Sidi Bel Abbes, ALGERIA 2 Dept. of Electronics, Faculty of Technology, University of Saida, Saida, ALGERIA E-mail: 1wboudkhil.abdelhakim@yahoo.fr, 2asma.ouzzani@yahoo.fr, 3sba_soudini@yahoo.fr ABSTRACT This article proposes a global study of an optical high debit chain presenting a complete simulation by comparing between the tree optical windows of telecommunications, led as an experience for teaching optical communications which are currently characterized by a grand demand for their exceptional transmission quality offering high debit, long distance of propagation and strong immunity against noise. The aim of this work extends to introduce the concepts and advantages provided by optical transmission systems using optical fiber, to observe and analyze the various limitations introduced in such systems and also to justify the choice of the optical window according to the use. Keywords: Optical Communication, Laser Diode, Optical Fiber, PIN Photodiode, Optical Windows. 1 INTRODUCTION Since the history of telecommunications knew its birth, the aim of researchers was always to optimize a system which provides more reliable transmission of information, and offers a very high capacity of transport for very long distances with all protection of transmitted information against all disturbances and noise which make the received signal different from that emitted. In this purpose, the crucial key to increase these performances has integrated optoelectronic components into telecommunications .
