SC328 - Standards for High-Speed Optical Networking
Monday, 31 March
13:30 - 17:30 (Pacific Time (US & Canada), UTC - 08:00)
Short Course Level: Intermediate
Instructor:
Tom Huber, Nokia, USA
This short course will be held in person only. Please check your email for information on the location where this short course will be held. If you need assistance please visit the Info Desk by registration.
Short Course Description:
This course provides details of a complementary set of standards for high-speed optical networking including the Optical Transport Network (OTN) and Flex-OTN standards developed by ITU-T Study Group 15, higher speed Ethernet (100 Gb/s and beyond) standards developed by IEEE 802.3, and the 400G and faster coherent optical interface Implementation Agreements developed by the Optical Internetworking Forum (OIF).
While OTN was initially developed for DWDM transport of SONET/SDH, it has evolved to provide a common convergence layer for IP and Ethernet traffic, as well as storage-area network, video distribution, and mobile fronthaul/backhaul traffic, providing full end-to-end management over a variety of network topologies at multi-gigabit per second data rates. OTN is being deployed by many operators in support of multiservice transport network applications, using multiple modulation formats and flexible grid networks. Recent standardization efforts, including the OIF 400ZR and 800ZR interfaces, which are primarily targeted at data center interconnect (DCI) applications, have blurred the line between OTN and Ethernet and focused attention on different network architectures that are better suited to those applications.
Participants will learn the basic features of OTN, Ethernet, and OIF ZR interfaces, with specific emphasis on recently added capabilities and how the various standards are related. The course will also include information related to ongoing work on 1.6T interfaces. They will also learn how networks can be built using these technologies and the advantages and disadvantages of the different types of interfaces.
Short Course Benefits:
This course should enable you to:
- Describe the capabilities provided to manage client signals and optical media/wavelengths.
- Identify the mapping mechanisms used by OTN to transport major client signals.
- Describe the structure and format for higher rates of Ethernet, including the interfaces specified by the OIF ZR Implementation Agreements.
- Discuss a range of industry efforts to incorporate DWDM technology and coherent modulation for a variety of applications.
- Explain the network configurations that can be supported with OTN, Ethernet, Flex Ethernet, and OIF ZR interfaces.
- Identify where to look to find more information about ITU-T Recommendations on OTN, IEEE 802.3 standards, and OIF Implementation Agreements
Short Course Audience:
This course is intended for anyone who designs, operates, or supports metro and/or long-haul optical networks for any application space (including telco, data center interconnect, storage area networking, and video distribution) and who needs to understand the latest standards related to OTN and Ethernet. Participants should have a basic understanding of transport networking technologies (e.g., SONET/SDH or OTN) and Ethernet.
The course has been revised to emphasize recent standards work related to 800G and beyond interfaces.
