Fibre optic cables in Africa

Fibres in Africa are comming

What can be advice for universities, researchers and governments?

Use world-wide experience, use up-to-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.

(Map is used from Duncan Martin presentation)

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, region-

wide, project-wide, continent-wide etc.) are responsible for inception, design, management and maintenance of research networks

Open Access 2006


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

Open Access 2006


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

Open Access 2006


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

Open Access 2006


CEF Networks workshops 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– presentations of CEF 2004

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)
