Speaker: Radhakrishna (Radha) Valiveti

Bio: Radhakrishna (Radha) Valiveti received his B. Tech degree in Electronics and Communication Engineering from the Indian Institute of Technology, Kharagpur, India. Subsequently, he earned his M.S. (Comp. Sc) from McGill University (Montreal, Canada), and a Ph.D. (EE) degree from Carleton University (Ottawa, Canada). Radha started his career by developing communication protocol software (e.g. X.25) at Philips (Montreal, Canada). Subsequently, at Nortel (Ottawa, Canada) he has architected and developed OSI protocols software for OSI Layers 2 through 5 (LAPD , CLNP, IS-IS, ES-IS, TP4, Session Layer) for Nortel’s line of optical network elements used to build SONET/SDH transport networks. In a later assignment at Nortel, Radha worked on defining the access network architecture in the Residential Broadband Access Group. Radha joined Fujitsu Network Communications (Richardson, Texas) in 1998, and has worked on the architecture and requirements for the Flashwave family of SONET/ATM hybrid ADMs, and the architecture of MPLS Pseudo-Wire (PW) based packet services for the Flashwave 9500 packet optical transport network element. Radha joined Infinera’s system architecture group in 2006. He is responsible for OTN support in Infinera’s DTN-X product. He also tracks and contributes to work in ITU-T SG15/WP3 questions Q9 (OTN Equipment) and Q11 (OTN signals and formats).

Title: Overview of Optical Transport Network (OTN)

Abstract: 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 – from pure TDM networks to ones that efficiently carry a mix of TDM/packet flows.

Speaker: Matthew Mitchell

Bio: Matt Mitchell received his M.S and Ph.D degrees in Electrical Engineering from Princeton University in 1995 and 1998 respectively. Upon finishing his Ph.D. he became a member of technical staff within the Advanced Development Department at Lucent Bell Laboratories working on high channel count DWDM transmission. In 2000, he become a member of technical staff at Corvis Communications serving as a technical lead in developing a next generation 10Gb/s DWDM long haul transport product. He has been with Infinera since mid 2001 and has contributed to numerous programs including optical architecture, hardware research and development, and the creation of optical system planning tools. He recently managed the hardware development team responsible for the next generation Infinera Line System (ILS2) product platform. He is currently a Senior Director managing the Optical Systems Architecture group. Dr. Mitchell is a member of the Optical Society of America, has co-authored more over 30 peer-reviewed publications and holds 16 patents in the area of optical transmission and nonlinear optics.

Title: Photonic Integrated Circuits (PICs) Scaling Next Generation Optical Networks

Abstract: 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. Infinera’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.

Speaker: Abhijeet Deore

Bio: Abhijeet Deore is a Senior Manager, Solutions Marketing at Infinera. His team is responsible for worldwide marketing of solutions built using Infinera’s broad range of products with a focus on data center and wholesale services market segments. His career spans over 13 years in the telecommunications industry having held several leadership positions in research and development prior to transitioning to a marketing focused function. Having joined Infinera in 2004, Mr. Deore led WDM embedded software development for 5 years. Over the past 2 years, he has led product marketing for Infinera’s Line System and DTN products lines. Prior to Infinera, Mr. Deore held systems development and product architecture positions at Ciena (2000 – 2004) and Alcatel-Lucent (1998 – 2000). He has contributed to the design and development of several successful switching and transmission products including Ciena’s CoreDirector and the Infinera DTN. Mr. Deore holds a Bachelor degree in Electronics and Telecommunications from the College of Engineering Technology, India. He also earned a Masters in Electrical and Computer Engineering from Duke University, Durham, N.C. In 2009, he completed his M.B.A from the Haas School of Business, University of California at Berkeley. He is a member of the IEEE and has contributed to several patents that have helped forward the evolution of telecommunication systems.

Title: Super-channels and the Future of Optical Networks

Abstract: 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.
