OTN DWDM Transport Properties
• Typically 8Tb/s – 9.6Tb/s per extended C-band.
• All Long Haul DWDM systems are based on proprietary OTUkV
format (proprietary FEC mechanisms and coherent detection
algorithms). There is no line side interoperability.
• PM-QPSK with 2bit/s/Hz spectral efficiency dominates terrestrial
applications
• In subsea applications special formats with spectral efficiencies in
the range 1bit/s/Hz – 3+bit/s/Hz (PM-BPSK – PM-8QAM, <50GHz
spacing)

Michael Enrico received his BSc and PhD
degrees in Physics from Lancaster University in 1991 and 1995. In 1997 he moved into telecommunications joining what was then BT
Labs, where he worked on: the study and development of innovative broadband access
network architectures based on hybrid fibre-copper infrastructures and highly scalable IP network transport solutions for broadband
services. In 2001, he joined DANTE’s Network Engineering and Planning team in which he
worked on various high and low level design assignments. In 2003, he was promoted to Network Engineering and Planning Manager and
in 2012 to CTO and is now responsible for developing technology strategies in DANTE and
the GÉANT project as well as representing these same entities on the international R&E networking stage.

100G Trunk Protection
• GÉANT “Western Ring” consists of 5 links each running 100GE
• Upgrade Path?
• Add a “direct” fully protected link between two sites
• If there is a fibre cut between CH & DE the “direct” link between CH & NL will get restored dynamically in ~50ms
• The IP traffic will use the same physical path it would have used if the ring was 2x100GE
• There will be no increase in traffic on IP link FR-UK or UK-NL or FR-CH
• Traffic between CH & DE will go via NL making CH only 2 IP hops away rather than 4

Exploring our Universe with eVLBI
Through dedicated high-speed
links, GÉANT connects remote
radio telescopes around the
world, providing researchers with
real-time distributed images of
the solar system.
“The EXPReS project has been transformed by our connection
to the GÉANT network. Whilst the advancement of telescope technology means we can now carry out years’ worth of
observations in days, the ability to then transfer that vast
quantity of data between astronomers at such high speed means the pace of our research has accelerated beyond
recognition, with real-time collaboration now a reality.” – Professor Ralph Spencer, Jodrell Bank Observatory)

INFINERA DTN-X: MULTI-TERABIT PACKET OPTICAL
TRANSPORT NETWORK (P-OTN) PLATFORM
Offering service providers operat ional simplicit y , cost -effect ive network
scale to mult i-terabit and superior PIC-enabled network ef f iciency
Why You Need the DTN-X
The relentless growth of video, mobile and cloud-based applications
demands a network that can deliver highbandwidth, market-leading
network economics. The In nera DTN-X integrates Photonic Inte-
grated Circuit (PIC) based multi-Terabit WDM transport and inte-
grated OTN switching to offer a combination of scale and ef ciency
while simplifying network operations. By combining plug-and-play
automated turn-up, GMPLS network intelligence and service automa-
tion, DTN-X provides a truly simple network and system architecture
leveraging high density, low power enabling PICs, delivering a ‘no
compromise’ Digital Optical Network.
What Is the DTN-X
The In nera DTN-X is a next generation mult i-Terabit converged
P-OTN solution. The DTN-X enables 5 Tb/s) of non-blocking switch-
ing in a single bay, upgradeable in the future to 10 Tb/s, scalable
to 100 Tb/s in a mult i-bay con gurat ion, and offering 8 Tb/s of
WDM capacity scalable to 24 Tb/s. DTN-X combines the bene ts
of PIC technology, integrated switching and the exibility of OTN
and packet. The DTN-X extends In nera’s leadership with the unique
Digital ROADM architecture and Generalized Multi-Protocol Label
Switching (GMPLS) service intelligence and is posit ioned to meet
the needs of service providers seeking to offer new and innovative
services in a SIMPLE, SCALABLE, and EFFICIENT manner.
Simple
The In nera DTN-X is simple to install, operate, troubleshoot and
scale. Services can be quickly and easily provisioned and transported
over a common WDM layer. The key enablers of network simplicity are:
PIC-enabled economical optical-electronic-
opt ical (O-E-O) conversion allows sub-lambda grooming while

IP/Optical Integration– IP Traffic Grooming
• IP traffic from router ports or sub-ports is mapped to the optimal transport
container
• Traffic is individually forwarded to its specific destination across the low-cost
optical layer with the highest reliability and quality.
• Maximum filling of optical transport resources avoids capacity waste
Flexible IP traffic grooming options at the OTN layer,
including port-level and sub-port-level grooming

OTN & MESH
• Anticipate that OTU client Interface requirement coming from
Telecom Carriers and large capacity consumers, for instance
Internet Service Providers and Cloud Service Providers
• Unprotected 10G services still in demand, OTN provides
grooming capabilities and flexibility for multi service traffic type – 40G on sub sea services now commonly requested
• Pacnet's multiple cable architecture, opens up offer of fast re
route, multi path back up/restore. Product offer key to
successful take up
• Holistic overlay approach, to deploy capabilities POP-POP or
Importantly DC-DC

OTN for UNI
• OTN for Intra-Domain IaDI is obviously mature BUT Inter-
Domain IrDI / UNI is not mature yet….
• Pacnet will look at inter vendor testing, PoC to realize potential
of OTN
(source : OTNtutorial.pdf)
Multiple Specification for OTU client interfaces will make more confusion
In Summary…
• Next Gen Transport Evolution will allow Pacnet
• Transition to a cost efficient Terrestrial and Sub Sea architecture
• Traffic grooming, multi services integration (TDM & Packet)
• MPLS+ETHERNET+OTN
• Network Scalability, Flexibility
• Leverage existing network footprint with multiple cable spans in region
• OTN Adoption is coming to the Sub Sea Environment
• Extend Pacnet's Optical domain to Enterprise, Carrier customer base
• Separate Data and Control Plane opens up future development
