Next Generation SDH
Start Date: Please contact us
Course Overview
Synchronous Digital Hierarchy, SDH, standardized the way information is multiplexed and transmitted in today’s optical transport networks. This course will teach how data/Ethernet is carried efficiently over SDH. This course will also teach the more advanced SDH topics, including: how to track who is responsible for any signal degradation as the traffic crosses through independent networks; the various line, sub-network and path protection options; and various extensions added to the SDH protocol. Additional topics that will be explained on a basic level will be: the packet protocols for transport such as MPLS, T-MPLS, PBB and PWE3; the new management protocols GMPLS and ASON; and a quick look at DWDM and the Optical Transport Network or OTN with range extending FEC. Finally the course will review the technologies competing for the Packet Optical Transport Market
