Where are we?
Some Svalbard facts
Between 74 and 81 degrees North
2527 Human citizens
3000 Polar Bear citizens
Main activity
• Coal Mining
• Research
• Tourism
Governed by Norway
Svalbard Treaty
Strict laws to protect the environment and the cultural heritage
Longyearbyen, the main village, at 78 degrees north, has a
university center, UNIS
Ny-Ålesund is a village at 79 degrees north dedicated research
Some Ny-Ålesund facts
Mining was main activity until 1962.
Between 30 – 300 citizens
Zeppelin harbor for north pole expeditions
around 1925
Ca 20 nations have permanent research
stations in Ny-Ålesund
A lot of research going on there, much
related to environment and climate
VLBI-station, 3rd most important in the
world

Svalbard: Network history and
activities in 2014-2015 (1)
Pre 2004; Satellite link to Svalbard; ~ 50 Mbps, mostly for NASA and NOAA. Only a limited number of ISDN
connections for the rest of us.
2004: Two cables laid from Longyearbyen to the mainland
Pre 2005: 64 kbps satellite link to Ny-Ålesund used by NMA and AWI, the rest of Ny-Ålesund shared an IPover-ISDN connection via a 2Mbps radiolink covering both POTS, Broadcasting etc.
2005: 2+0 STM-1 radiolink with approx. 140 Mbit/s UNINETT connection, the rest for TV and POTS
2006: Successful eVLBI trials. Fully operational in production soon afterwards.
2016/17: NMA preplanning of a new VLBI station able to produce 2x10 Gbit/s per node

Svalbard: network history and
activities in 2014-2015 (2)
2008: A brief calculation on the cost of a subsea cable
2010: Funding surprise: ~7.5 M€ from the government for a new cable which have been extended to ~11M€ MNOK in
order to deploy two redundant cable path.
2013: signed fiber cable deployment contract with Global Marine System
2014: ongoing submarine cable deployment. Finished by the end of September
We are running a tender process in order to deploy DWDM equipment. Expected DWDM system ready for service by April
2015
Parallel with DWDM deployment we will upgrade our IP-network in Svalbard too.
Some facts about Ny-Ålesund Longyearbyen
submarine cable
Two cable route
Distance: about 260km per route
(less than 50dB fiber loss)
Cable will be partly buried (<2 m)
and partly laid on surface
Cable landing points are secured by
Horizontal Directional Drilling (HDD)
against icebergs and other shore
events
Line Termination equipment will be
collocated with mainland SLTE in
Longyearbyen
ROV (Remotely Operated Vehicle)

Ny-Ålesund Submarine cable route
Submarine Cable
Submarine Cable Network,
Some terminology
Mainland Connectivity options
1.
Running UNINETTs connections as Wavelength services and subwavelength services
2.
Alien Wavelength over TE-subcom submarine DWDM system
3.
Sharing Optical Spectrum on one fiber pair
4.
Using another fiber pair and install parallel SLTE
1.
Both DWDM (LTE) and LMS delivered by TE
2.
DWDM (LTE) delivered by third-party but LMS delivered by TE and
managed by Telenor
3.
DWDM (LTE) delivered by third-party but LMS delivered by TE and
managed by UNINETT
4.
both DWDM (LTE) and LMS delivered by 3.party
Drivers for a cable to Ny-Ålesund
e-VLBI, and a new observatory planned from 2016 –
much more capacity needed! (Very-long-baseline interferometry)
Need for a more reliable network solution than today´s
one link radio solution can offer.
Increasing research activity
The end of the radiolink – environmental risk of fuel
leakage on the relay station.
New VLBI station
Uninett Network Services
Dedicated Capacity
Lambda and sub-lambda services
No layer two services. Layer two service deployment policy is under discussion.

Summary
Submarine cable deployment by the end of September 2014
DWDM deployment by April 2015
Upgrading of IP-network by Q1/2015
Svalbard – Mainland connection by leased capacity and
leased wavelength in 2015.
Looking for alternative Mainland connectivity solution for
future deployment
VLBI is the main driver but there are many other research
activities that will benefit of high capacity connectivity to
Ny-Ålesund.
