ECE401OPTICAL COMMUNICATION AND NETWORKS L T P C2 0 0 2Version1.1Aim and Objectives:The aim and objective of the course is to impart knowledge on optical fibers, sources, detectors and amplifiers to design point to point optical systems, WDM systems and to understand SONET/SDH network architectures

OUTCOMES:1. Ability to design, analyze and evaluate the performance of optical communication systems.2. Ability to solve the problems arising due to the non linearities of optical fibers.
