Fibre optic cables in Africa

Fibres in Africa are comming

What can be advice for universities,
researchers and governments?

Use world-wide experience, use upto-date technology, avoid repeating
of mistakes.

It looks simple.....

Problems are in details and in decisions
about rules and priorities (as usually)

Research networking is investment
to the development of society



Research networking supports
education, prosperity and
development in other sectors of
society
Research networking stimulates
international collaboration and
funding
Research networks are high-end
products, using multiple 10 Gb/s
transmission rates today. This
strongly stimulates information
technology development and
application.

Remember





The Internet had its origins in the world of research and universities and
research networks are still the most advanced part of the Internet
Close collaboration of universities and research institutions is success factor for
research networking (used mostly also for education, health care etc.)
Research networks
– are an important source of Internet innovation
– are largely funded from taxpayers’money
– contribute to information technology innovation and deployment, and
hence to economic prosperity
The research networking environment drives the development of the Internet
– It develops new technologies and services
– It produces university graduates who expect advanced information
technology applications
Consortiums of universities and research institutions (country-wide, regionwide, project-wide, continent-wide etc.) are responsible for inception, design,
management and maintenance of research networks

Knowledge is key

Electronic and photonic technology development is tremendous source of
innovation of legacy optical networks, especialy:
– photonics transmission systems (including fibres, lasers, receivers,
dispersion compensators, optical switches etc.)
– photonic integrated circuits (multiple OEO conversion on chip, etc.)
– programmable hardware (FPGA etc.)

Improvement of transmission parameters and cost is so strong, that the move
towards advanced electronic and photonic technology in networking is a
fundamental change that will not be reversed (remember story of mainframe
computers in the age of integrated circuits)

Direct access to high-end electronic and photonic technology resources
including fibres is a critical requirement of research networks – to stay in
leading edge of Internet development, to promote research and education
world-wide and as a spearhead for the development in other sectors of society

Legacy research networks

Past approach to research networks design and deployment:
– lease SDH/SONET from telco operator
– buy or lease equipment from one of dominant vendors (mostly using
backbone oriented architecture)


Main disadvantage: dependency on telco operator and equipment
vendor during network life cycle, resulting mostly in slow
innovation and high costs (in contradiction with research
networking mission). Nevertheless, work for profit is not mistake
of telco operators or equipment vendors.
This means consortium requirements concerning research
networks design, deployment, operation and innovation
should be improved

Leapfrogging






Improvement of legacy research networks is rather difficult, time
consuming and expensive
Well-known method is to build new research network, replacing
gradually the old one
Dissemination of experience can avoid repeating of mistakes
Research networks which are building their infrastructure from
scratch can avoid investing into concepts, equipment and
technologies which are past
Lack of legacy can be an advantage (but lack of knowledge and
lack of funding are always serious limitation)
We can speak about East Europan Leapfrogging in Czech Rep.,
Poland and Slovakia (although not in geographical sense)

Research networks vision




Research network life-cycle is from inception, design, management,
maintenance and upgrades up to end of life (replacing by new research
network)
Consortium is responsible for network life-cycle. Realization of above tasks
can be fully or partially outsourced, if working capacity or special knowledge
is missing in consortium (and funding is sufficient).
Consortium should maintain own ability to immediatelly use networking
research results, results of fibre footprint development and new types of
electronic and photonic products.
Important requests are:
–
–
–
–
–

Fibres (including last mile) dedicated to research network are crucial
Freedom of improvement and independency on vendors (mixed vendor approach)
Ability to quick return and correct design (including re-tendering etc.)
Interoperability of devices and Multisourcing (MSA)
Pre-procurrement with fibre providers and electronic and photonic industry
(including collaboration on proposals of standards)
Customer Empowered Network (CEF) concept aims to support this vision

One of the most important opportunities to exchange ideas about Customer
Empowered Fibre Networks world-wide research and development are
workshops in Prague. You can see

Steps to vision




Acquiring first dark fibre (324 km) for CESNET in 2000, STM-16 transmission
Using new advanced photonic products for 189 km STM-16 transmission
without any in-line devices since 2002 (i.e. mixed vendor network design)
Bratislava (SK) – Brno (CZ) GE since 2003, now DWDM NIL over 190km
Cieszyn (PL) – Ostrava (CZ) GE since 2004, now DWDM n x 10 Gb/s
Brno (CZ) – Wien (AT) since 2006, DWDM NIL 8 x 10 Gb/s over 224 km

Upgrade of dark fibre lease service to lit fibre lease service is prepared for 4 dark fibre
lines of CESNET network now (experiment with partial outsourcing)
– no return to SDH or lambda lease for research networks
– fibre provider will deliver more service (for example lease, installation and
maintenance of DWDM lighting devices designed and managed by research
network

For offer of full outsourcing see new announcement of Fiberco in US:
– Offerings include but are not limited to: network architecture and design,
installation, staging and implementation services, order management and asset
tracking, and 24 x 7 x 365 operations support.

DWDM NIL 8 x 10 Gb/s over 224 km



All devices have been installed only at the end points of
the line in Brno (CZ) and Wien (AT) and no in-line
elements have been deployed.
Nothing In Line (NIL) approach has been used and
according to our knowledge, 8 times 10 Gb/s over 224
km of dark fibre is the longest NIL distance that has
been reported for any research or ISP network.
The main advantage of NIL solution is represented by
lower capital and operational costs and increased
reliability.

Enabled by advanced photonic technology

The fibre pair from Brno to Vienna has been equipped
with CLA PB02 optical amplifiers, developed as a part
of optical research activities of CESNET.
Chromatic dispersion of G.652 optical fibre has been
compensated by new compensating elements – Fiber
Bragg Gratings (FBG).
Terminal routers are equipped with Xenpak DWDM
pluggable optical transceivers.
First two companies have started CLA manufacturing.
First ISP has started usage of CLA.

Dark Fibres are crossing Borders




Dark fibres connecting capitals or main PoPs, as in GEANT2 core or in
National Lambda Rail (NLR) in US are crossing state borders, of course.
By Cross Border Fibre (CBF) we mean other fibres, connecting PoPs close to
border
CBFs are usually short and non-expensive and carry high traffic between
neighbour NRENs, saving expensive long distance fibres capacity
Research networks can provide long distance international lambdas using
CBFs, national fibre footprints and DWDM technology
---------------------------------------------------------------------------------------------------See next picture for European fibre footprint used for research networking – there
are still big gaps, but many improvements are coming (e.g. in Nordunet
countries- see 23rd Nordunet Conference)


August 2006: SEEREN2 has enabled a
second access port to GEANT2 using
Dark Fibre (limited international IP
commodity though)
September 2006: SEEREN2 is the first
EU funded regional project that builds
international cross border link based
purely on dark-fibre services. Link to
provide connectivity to 3 or more
universities in B&H
Current status:
– CWDM equipment delivered to
BiH
– Physical testing & measurements of
the fibre almost completed
A few numbers: 255 Kilometers, 7
different spans, 5 installation in
collocation centers
Support for 2 P2P links using GigE
services
