Zhuge, Ciena Canada,
Canada
Flexible coherent systems with programmable 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 deployment experience. In particular, the
following questions will be addressed:
What flexibilities could currently deployed systems deliver, versus what
flexibilities are actually being utilized?
What gains (e.g. capacity improvement, cost reductions, deployment
efficiencies and operational simplifications) are being achieved with these
initial deployments? What is the path
to upgrade these systems to take advantage of the full flexibility, and what
are the challenges and perceived ultimate gain? Based on the experience
of the initial deployments, what are
the directions for future development
of flexible systems and components?

Danny Peterson, Verizon
Communications Inc., USA
Since the advent of coherent technologies in 2008 (which opened the way to
electronically compensating for various 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 telecommunications, new fiber types are
again starting to be deployed. Experts
representing major carriers, fiber manufacturers and users will discuss new
ultra-large area, ultra-low loss, hollowcore singlemode and wideband multimode 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.

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 efficiencies 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 implementation, 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 argumentative thoughts on how the network would/
could/should evolve in the next 5 to 10 years.

The unceasing growth of data, of web
services and of fixed and mobile cloud
computing applications is creating the
need for novel data center architectures that offer improved performance,
energy efficiency and economics. This
applies to stand-alone mega-scale
data centers as well as to clusters of
small to large data centers that are
interconnected over a geographical
area. Such architectures need to take
full advantage of the latest advances
in electronic and photonic processing,
interconnect and switching technologies, data storage devices as well as
control and management solutions
including robust and flexible softwaredefined networking, and security
measures. A panel of experts will
address these topics, will provide
insights regarding the current technology trends and share their visions for
next-generation data center architectures. Sufficient time will be provided
to facilitate addressing questions and

is a second source of data to predict

Organizer: Howard Kidorf,

Until recently, independent groups
have engineered terrestrial and submarine networks with different design

ecosystems.Advances in coherent modems 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 equipment 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

Engineering, Soochow Univ., China.
All-optical multicasting with a single
light-tree suffers inefficient distanceadaptive spectrum allocation from its
large tree-spanning size. We propose
a routing modulation format and
spectrum allocation (RMSA) algorithm
based on sub-tree scheme to improve
spectrum utilization.

Home Network Direction, Telefónica
Investigación y Desarrollo, Spain. A
new optical monitoring system for

Chenhui Ye1, Xiaofeng Hu1, Xiaoan
Huang1, Qingjiang Chang1, Zhensen
Gao1, Simiao Xiao1, Xiao Sun1, Kaibin Zhang1; 1Alcatel-Lucent Bell Labs
Shanghai, China. We proposed and

in-building mobile communication
of 200X 20MHz MIMO LTE-A signals
over sequential wireless-interface,
economical twisted copper lines and
fiber between UEs and centralized
BBUs in the uplink direction.

Reconfiguring TWDM PONs, based

Laboratoire Charles Fabry, Institut

M. Bilal1, Antonino Nespola2, Pierluigi Poggiolini1, Fabrizio Forghieri3;

Politecnico di Torino, Italy; 2Istituto

Photonics, Italy. We show that the
impact of non-ideal time synchronization between in-phase and quadrature
electrical signals can be critical in
multi-subcarrier systems. We propose
the use of an 8x8 real-valued butterfly
equalizer structure to mitigate it.
Tipping point for the future scalable OXC -What size MxM WSS

Modulation or Flexible

Organizers: Jörg-Peter
Elbers, ADVA Optical
Networking, Germany and
Gernot Göger, Huawei,
Germany
Flexible grid ROADMs and bandwidthvariable transponders will furnish
optical transport networks with unprecedented levels of flexibility.
Programmable ROADMs allow bandwidth management with sub-50 GHz
granularity. Future bandwidth-variable 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 addresses decisive criteria for the choice
of the network upgrade path:
• How do network benefits contrast
with increasing equipment cost?
• How can the operational complexity of flexibility best be handled?
• What are the challenges in transceiver 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. Technoeconomic analyses comparing the ITU-T/FSAN
GPON family of standards (incl. XG-PON1, NGPON2 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 addresses electro-optical components such as
lasers, modulators, filters and receivers suited
for Gigabit speeds and beyond.
