40028 «Optical Networks System Survey»

Course Code




Optical Communications are nowadays gaining more appreciation on telecom transmission networks. Cellular networks are one of these cases, specially after the all IP solution over Ethernet and Optical physical medium

This material contains a fundamental approach to the optical components (Optical Fibers, Optical Sources & Optical receivers, amplifiers, etc) that compose an optical network. Understanding fundamental theory of fiber optics is a must for nowadays engineers. Planning of Optical network (power budget planning or service throughput planning) is explained and the well known WDM technique is explained. Moreover a more detailed explanation of IP, Ethernet and SDH/PDH over optical is explained

Practical exercises and planning case studies are discussed
