Representatives from Infinera Corp will describe the evolution of the ITU-T standardized Optical Transport Network (OTN), Super-Channels and future directions for DWDM based optical networks, and an overview of Photonic Integrated Circuits (PICs).? The three presentations will be followed by a lively panel session, with audience participation via pre-submitted questions and live Q and A.
Topic: Overview of Optical Transport Network (OTN)
Radhakrishna (Radha) Valiveti, Architect, System Architecture Group
The first generation of OTN standards were defined by ITU-T Recommendation G.709 around the 1999-2001 timeframe.? This generation of OTN standards supported SONET/SDH clients as their primary client signals.? OTN standards have since undergone significant changes to support dominant Ethernet Client signals such as 1/10/40/100GE.? The latest version of OTN standards are defined in G.709 [12/2009] and the key extensions include the support for the Ethernet client signals identified above, and a flexible rate ODU which can support client signals with arbitrary rates.? At ITU-T, work has recently begun on the definition of the next generation of standard OTN containers.? Infinera is actively tracking and contributing to the emerging optical network standards.? The talk will provide a status of the OTN standardization effort in ITU-T and discuss the evolution of OTN networks â?? from pure TDM networks to ones that efficiently carry a mix of TDM/packet flows.
Topic: Super-channels and the Future of Optical Networks
Abhijeet Deore, Sr. Manager, Product Marketing
Super-channels represent the future of the industry and bandwidth evolution to beyond what 100G can deliver.? We will discuss what super-channels are, if and why they might be needed, and their benefits.? The presentation will also cover a realistic timeline for super-channels, key building blocks that could enable super-channels in a practical real-world implementation and technological challenges of increasing fiber capacity in absence of super-channels.? We’ll investigate whether the 100G coherent networks of now (and the near future) are well suited to evolving into super-channel optical networks.? Super-channels are currently being discussed by the ITU-T SG15/WP2/Q6 standards group.
Topic: Photonic Integrated Circuits (PICs) â?? Scaling Next Generation Optical Networks
Matthew Mitchell, Sr. Director, Optical Architecture
Commercially produced photonic integrated circuits (PICs) used in optical networking equipment was brought to the market in 2004.? This important technological breakthrough drastically simplified the design of an optical networking solution, increasing the density of the platform so more bandwidth can be carried by a smaller, more efficient platform.? Infineraâ??s first generation PICs integrate 62 optical components onto a pair of monolithic chips and deliver 100 Gigabits per second of bandwidth capacity.? This was the first time the technique of large-scale monolithic integration was applied to commercial photonic chips.? Today, Infinera has produced PICs delivering five times the capacity onto a single pair of chips, integrating more than 600 optical functions.? This presentation will describe how InP PICs are used in optical networking solutions and the advantages of PIC-based optical networking platforms.? InP based integrated circuits provide high optical performance relative to a silicon or hybrid silicon optical approaches.
