Flexible coherent systems with pro-grammable coherent transceivers and flexgrid CD or CDC ROADMs are being deployed currently. Comprising service providers, system vendors, and component/ subsystem suppliers, this panel will share views on use cases, perceived benefits, and initial deploy-ment experience. In particular, the following questions will be addressed: What flexibilities could currently de-ployed systems deliver, versus what flexibilities are actually being utilized? What gains (e.g. capacity improve-ment, cost reductions, deployment efficiencies and operational simplifica-tions) are being achieved with these initial deployments? What is the path to upgrade these systems to take ad-vantage of the full flexibility, and what are the challenges and perceived ulti-mate gain? Based on the experience of the initial deployments, what are the directions for future development of flexible systems and components?

Since the advent of coherent technolo-gies in 2008 (which opened the way to electronically compensating for vari-ous impairments, such as dispersion), emphasis has been placed on using standard ITU-T G.652 fiber. But today, with ever-increasing requirements on optical fibers used in data and tele-communications, new fiber types are again starting to be deployed. Experts representing major carriers, fiber man-ufacturers and users will discuss new ultra-large area, ultra-low loss, hollow-core singlemode and wideband mul-timode fibers. These advanced fiber types address markets from long-haul communications to financial services and data centers. Questions to be addressed include: How important is backward compatibility? What are tolerable connection (splice) losses? How much performance advantage do these fibers bring relative to their cost? What kinds of fibers address future market needs?This Panel Discussion to take place in two parts; Long-haul “conventional” fibers, and short-haul/data center fibers. Each speaker will give 10 minute presentations followed by 20 minutes of discussion.

16:00–18:00M3J • Panel: Network Evolution Paths: From Integrated Superchannels to High-Speed Single-Carrier Networking Solutions Organizer: S. Chandrasekhar, Nokia, Bell Labs, USA

Capacity demands on transmission systems have spurred innovative solutions to deliver large information rates at high spectral efficien-cies over wide-area optically routed networks. Solutions include multi-carrier superchannels that exploit optical parallelism and array integration, as well as single-carrier solutions at very high symbol rates and higher-order modulation that leverages advancing high speed electronics. A common example in the industry today is the delivery of 400-Gb/s either with 10 integrated sub-carriers using 16-Gbaud QPSK, with dual-carrier 32-Gbaud/carrier 16QAM, with a single carrier using 64-Gbaud 16QAM, or with 44-Gbaud 64QAM. Next generation systems are envisioned to support Terabit interface rates. Each approach has its pros and cons and challenges from imple-mentation, performance, network elements, and networking impact. This panel discussion brings together knowledgeable experts from a cross-section of our industry to examine the evolution of optical networks in the light of the above choices. Panelists include visionaries from service providers, system and subsystem vendors, network architects, and researchers. They will examine the theme from different angles and offer both constructive and argu-mentative thoughts on how the network would/could/should evolve in the next 5 to 10 years.

It is staggering just how much optical communi-cation has changed the world and consequent-ly almost every aspect of our everyday lives. The pace of technology change is unrelenting - with new applications and technical means to meet the ever growing data capacity demands and high levels of connectivity required always around the corner. This symposium is intended to help us imagine the future of fiber commu-nications technology and its uses. It will bring together renowned visionaries in several key fields, both users and technology pioneers, to share their vision of the future connected world, to speculate as to the exciting things we may soon be doing, and what will be required from a technology perspective to address emerging and ever expanding user needs.

08:00–10:00W1C • Panel: Convergence between Submarine and Terrestrial NetworksOrganizer: Howard Kidorf, Pioneer Consulting, USA

Until recently, independent groups have engineered terrestrial and sub-marine networks with different design rules and with separate supplier ecosystems.Advances in coherent mo-dems and other agile devices for submarine and terrestrial applications are now merging the functionality of submarine and terrestrial networks.This groundbreaking panel will explore how the resulting new equipment ecosystems and modified network architectures offer increased agility to both network engineers and equip-ment suppliers.We will hear views of this transformation from new network investors (e.g., Google, Facebook, Microsoft), the challenged traditional carriers, submarine system suppliers throughout the supply chain, and terrestrial equipment suppliers.This panel will tackle the elimination of sub-sea backhaul, “open” undersea cables, commercial and contracting difficulties, upgrade economics, and the new technologies that will chal-lenge yesterday’s view of network architecture.

13:00–15:00Th3A • High Bandwidth TransceiversPresider: Andre Richter; VPIphotonics, Germany

13:00–15:00Th3B • Panel: Flexible Modulation or Flexible Bandwidth, Which One Comes First?Organizers: Jörg-Peter Elbers, ADVA Optical Networking, Germany and Gernot Göger, Huawei, Germany

Flexible grid ROADMs and bandwidth-variable transponders will furnish optical transport networks with un-precedented levels of flexibility. Programmable ROADMs allow band-width management with sub-50 GHz granularity. Future bandwidth-vari-able transponders may use adaptive modulation as well as adaptive and sliceable optical bandwidth. Thereby network utilization can be optimized by simultaneous consideration of spectral usage and reach. Currently flexible modulation transponders and super-channels are on the verge of commercialization. However, both technologies come at the expense of additional equipment cost and operational complexity. This panel ad-dresses decisive criteria for the choice of the network upgrade path:

• How do network benefits contrast with increasing equipment cost?

• How can the operational complex-ity of flexibility best be handled?

• What are the challenges in trans-ceiver and ROADM design?

• Will flexible modulation or flexible bandwidth technologies first be used in commercial networks?

This panel addresses deployable technologies and the techno-economics of Gigabit access networks, looking at architectures ranging from residential to business applications as well as mobile backhaul and C-RAN fronthaul.As more operators start to offer Gigabit services, larger deployment volumes are shifting cost/performance numbers significantly. Techno-economic analyses comparing the ITU-T/FSAN GPON family of standards (incl. XG-PON1, NG-PON2 and XGS-PON), IEEE EPON group of standards (incl. 10G-EPON and NG-EPON) and emerging solutions for TWDM-PON enable operators to select the solutions best suited for their needs. Copper-based technologies (DOCSIS 3.1, G.fast) to bridge the remaining distance from fiber to customer will continue to play an important role.The panel also ad-dresses electro-optical components such as lasers, modulators, filters and receivers suited for Gigabit speeds and beyond.

Th4E.5 • 16:45 Invited Ultra Low-loss Optical Fiber Technology, Sergey Ten1; 1Corning Incorporated, USA. Since inception silica based optical fibers have demonstrated dramatic attenuation reduction from 20 dB/km to 0.1460 dB/km. Ultra-low level of attenuation is enabled by silica core fiber design and reduction of the largest attenuation component - Rayleigh scattering.
