What is the “Optical Reboot”?
 Coined by Andrew Schmitt from Infonetics
• Describes the transformation (as opposed to evolution) of
optical transport networks in response to an exponential
growth in demand
• Characteristics include:
This will be the focus
• The move to coherent transmission
for my presentation
• The need for integrated OTN switching
• The need for CDC ROADM technology
• The need for a dynamic control plane (eg. GMPLS)

Agenda
 Coherent technologies enable 100Gb/s transmission,
with outstanding reach and spectral efficiency
 But how do we continue to scale the operational
aspects of coherent technology?
• Moving beyond 100Gb/s per channel
• Coherent super-channels
 Engineering the “ideal super-channel”
• The move to multi-carrier
• The role of photonic integration

The “miracle” of coherent transmission
10Gb/s per channel
80 channels = 800Gb/s
100Gb/s per channel
80 channels = 8Tb/s
A simple transmitter, and even
simpler detector with no
significant signal processing
A complex transmitter, and even
more complex detector with
very significant signal processing

Internet demand is growing at 30-40% CAGR:
How do we go “Beyond 100G”?
100Gb/s
Coherent
Technology
Today the optoelectronics does not
have the power to
sample beyond about
32GBaud
Delivers 100Gb/s,
single carrier, PM-QPSK
with 3,000km reach
Wait for the electronics
to “catch up”
Competitive
disadvantage
Use “higher order” modulation
(eg. 16QAM) to take the load off
the electronics
16QAM is a
“metro reach”
Complementary
modulation
techniques
Use multi-carrier super-channels
Broad industry consensus that super-channels
are the way forward for >100G

A super-channel
implements multiple

single line card…
All carriers
provisioned in

Heavy Reading White Paper
Available free at : www.infinera.com/solutions/whitepapers.html
“As suppliers look to 100G and beyond, we are
hearing an increasing consensus among them
that the super-channel is the best solution.”
“As we move to the 100G era and beyond, the
use of photonic integration becomes more
pervasive and, ultimately, mandatory.”

Senior Analyst, Heavy Reading

The Submarine Networking Reboot:

“Evolution” of the line system can only deliver a limited increase in capacity
– to meet predicted demand increase, an “optical reboot” is essential

Summary: What I talked about today
 The optical reboot is about revolution, not evolution
 A move to coherent transmission produces at least a
10X improvement in spectral efficiency, and usually
an improvement in optical reach
 Super-channels offer a way to scale network
operations for coherent technologies
• 5X or 10X the backbone capacity for the same operational effort
 Photonic integration is essential for the
implementation of practical super-channels
18 | Infinera Confidential & Proprietary
Summary: What I did not talk about today
 Integrated switching is vital part of the optical reboot
• Essential for the efficient use of 100G and super-channel capacity
• Enables effective control planes
 ROADM technology is in a state of flux today
• Ongoing challenge to deliver full CDC economically
• About to encounter the move from fixed grid to flexible grid
 Dynamic control planes drive down OpEx
• But they require digital switching to work effectively
• GMPLS is the proven technology today
• SDN looks like it can solve several interesting problems, but is immature
in the context of transport networks
