Panel II: Optical Layer Flexibility with Next Generation ROADMs

Panel II: Optical Layer Flexibility with Next Generation ROADMs

Wednesday, 23 March
13:30 - 15:00

Tiejun J. Xia, Verizon Communications Inc., USA

Panel Description:

The next generation ROADMs which support colorless, directionless, and even contention-less functions, have begun to be deployed in service providers networks.  With this advancement it makes a lot of sense to introduce an SDN type of control to form an orchestration layer to manage all of the network resources. This panel of carriers will explore the vast and newer applications of next generation ROADMs. Interesting aspects investigated will be the potential enablement of new services, which will benefit both networking service providers and their customers. The panel will provide comprehensive answers to the following questions:

•For incumbent service providers, how to will you leverage the opportunities of SDN optical transport?

•Which types of applications will be benefit first with the introduction of flexible optics?

•How soon can networks recognize new efficiencies delivered by these new features such as reliable traffic restoration, spectrum defragmentation, and fast capacity re-allocation?

•Will flex grid and superchannels have an impact on reconfigurable architectures?

Mitsunori Fukutoku
Mitsunori Fukutoku received B.E. and M.E. Degrees in electrical engineering from Tokushima University in 1989 and 1991, respectively.  He joined NTT labs in 1991. In 1999, he joined NTT communications, where he planned to deploy long haul WDM system. In 2006, he joined NTT west, where he develops Metro Ethernet System. From 2009 he belongs to NTT Network Innovation labs, where he is a group leader.  His research interest includes ROADM system in Metro Network and Optical devices.

Dan Marom 
Dan Marom is an Associate Professor in the Applied Physics Department at Hebrew University, Israel, heading the Photonic Devices Group. He received the B.Sc. (1989) and M.Sc. (1989) degrees from Tel Aviv University, and was awarded a Ph.D. in Elec. Eng. from the University of California, San Diego (UCSD), in 2000. His research interests include photonic devices and sub-systems using guided-wave and free-space optics, all-optical signal processing, optical switching technology, ultrafast optics and communications, and nonlinear optics.

Glen Wellbrock
Glenn Wellbrock is the Director of Optical Transport Network Architecture and Design at Verizon, where he is responsible for the development of new technologies for both the metro and long haul transport infrastructure.  Previous positions include running the advanced technology lab, establishing evaluation criteria, and setting engineering guidelines for all backbone transport equipment as well as various positions within network operations.  In addition to his 20+ years at Verizon (1984-2001 & 2004-present), Glenn was responsible for Product Architecture within the USA focused optical networks group at Marconi and Product Planning at Qplus Networks with a specific focus on developing alternative modulation techniques.
