Course content

The course will give the student in-depth understanding of the functionality of optical networks and how they may be implemented. How an optical network can work together with an IP-based network infrastructure for ensuring both high reliability and performance in access, metro and transport networks, is paid special attention. Protocols, e.g. MPLS-TP, GMPLS, SDN, OTN, and Ethernet PBB-TE will be addressed. The topics covered includes building blocks for optical networks and systems. Included is an introduction to optical components, principles and functionality in optical network elements as well as basic physical principles and properties and constraints in optical fiber transmission. Principles and the function of optical circuit switched networks, both network elements like reconfigurable add/drops and optical cross-connects as well as the principle of a wavelength routed optical network are covered. Finally, up-to-date research in optical packet switched node and network architectures is studied.
