What you will learn:
You'll learn how OTN frames are structured, how the OTN multiplexing hierarchy works, and how OTN provides the operations, administration, and maintenance (OAM) capabilities that network operators rely on for fault management and performance monitoring. The course also covers the integration of OTN with ROADM-based optical networking and the implications for network flexibility and capacity.
By the end of this course you will be able to:
- describe the characteristics required for the telecommunications networks that provide services to residential and business customers.
- explain the transition from TDM to IP-based service provision and the challenges involved in providing a comparable service.
- describe and compare the role and facilities of the various transport technologies and protocols that may be employed in a telecoms network
- explain the factors that influence the capacity of DWDM optical links.
- explain the advantages of optical switching with references to the facilities provided by a reconfigurable add-drop multiplexer (ROADM).
- explain how client signals are transported over an optical transport network (OTN) as specified by the ITU in recommendation G.709.
- describe the role and provision of OAM facilities and automatic protection switching in an OTN.
- describe and compare methods of mapping client signals into the payload of OTN transport signals.
- compare methods of providing connection oriented services in an OTN with reference to the use of MPLS, Carrier Ethernet, and OTN switching.
- describe the characteristics and typical applications of fine grain OTN services that provide low bit rate, ultra-low latency connections with stable timing distribution.
- describe and compare the benefits of possible protocol combinations in aggregation and core networks including those using OTN switching and transport.
- describe and compare possible architectures for an optical transport network.
