Annexure ‘CD – 01’ FORMAT FOR COURSE CURRICULUM Course Title: Optical Fiber and Communication Course Code: L T P/S SW/F W 3 1 - - TOTAL CREDIT UNITS 04 Credit Units: 4 Course Objectives: The objective of the present course is to introduce fundamentals of optical fibers, detectors and amplifiers and their applications in communication system. Pre-requisites: Students must have the knowledge of laws and principle of optics, electromagnetic theory, semiconductor materials and devices and communication system. Student Learning Outcomes: On completion of this course, the students will be able to demonstrate knowledge of the optical laws and definitions of Classify fibers as single-mode, multimode, step index, and graded index .From module II, they will understand the hard core theory of modal analysis and describe modes in multimode fibers and mode field parameter in single-mode fibers. From module III & IV they learn about the various sources and components of optical fiber communication system.
