This course presents the state-of-the-art in the field of Optical communication networks which encompasses traditional networks operating on optical fiber as well as the next-generation networks such as wavelength division multiplexed and optical time division multiplexed networks. The course will enable the students to learn about key photonic devices that form the backbone of the optical communication network. The course will provide students with a fundamental understanding of optical communication network design, control, and management. Students will do design of analog and digital optical fiber link and WDM network design.
