Course Overview

Synchronous Digital Hierarchy, SDH, standardized the way information is multiplexed and transmitted over fiber-based Optical Transport Networks. This seminar provides the fundamental basics of PDH and SDH transport networks and protocols. This seminar also provides the background needed to understand more advanced transport topics, such as, how packet data can be carried efficiently over SDH.
