Understanding of physical layer is crucial
to enhance applications
There are no applications without physical layer
Technology used in physical layer limits transmission speed and
applications (by latency, non-determinism etc.). Savings of
energy, space and costs must be solved primarily in physical layer
design.
There is electronic processing speed limitation (about 100 Gb/s
per port), optical processing speed limitation will be about 1 Tb/s
per port. Optical processing has significantly lower energy
consumption. See for example presentation Tetsuya Miyazaki:
“Node and Link Technologies for New Generation Networks”,
NICT, http://www.ict-fireworks.eu/fileadmin/events/910_June_2008_Brussels/Presentations/09-06-08/5B-Photonic_Networks/15TETSUYA_MIYAZAKI_-_Photonic_Networks.pdf

Experimentation based on physical layer
technology advances
The main source of possibilities to enhance applications lies in
physical layer.
In many cases we can gauge before network users, what new
physical layer possibilities will bring improvements for future use
Research and Development driven by experiments is important to
verify and evaluate real possibilities, create new service offers for
users, and find early adopters
For example, main improvements of Research and Education
networks physical layer are:

In the past: dark fibres instead of telco services (although not in
all lines)

In the future: photonic devices instead of electronic devices
(although not in all positions)
In GLIF: enhancing applications by connecting dispersed users to
GOLE

Devices for network research and experimentation
CESNET has developed family of open photonic devices (CL family),
enabling early adoption of leading edge photonic technology
Delivery from FTTx development company is available
Supports future network research and experimentation on dark fibre
level, fast testing and prototyping, support experimental applications
requested by users or field experiments on dark fibre lines verifying
feasibility of network improvements
Proved very useful for GLIF applications development (especially for
dispersed end users), CESNET2 NREN development, Experimental
Facility development, CBF lighting, FTTx deployment, improvement of
interoperability on the physical layer, as well as remote monitoring and
control, low latency and deterministic multicast (see GLIF demos 2007
and 2008)
Main building elements are photonics components (mux/demux, VMUX,
OA, ROADM, FBG, photonic switch, photonic multicast switch), industry
PC kits, unix and other open source sw
Main advantages: freedom of design, ability to meet user needs, easy
to modify if needs change, avoid delays in innovation (low needs to
save investments), photonic transmission and processing speed, low
cost, saving energy, space and user care.

Multicasting device demonstration
CLM (Multicast Switch) has
 photonic part multicasting (replicating) optical signal bands
 electronic part for remote switching control via web interface
Multicast by CLM is deterministic without jitter and delay, i.e.
without OEO conversion, without store and forward processing
and without loading of switch by multiple tasks
Operation demonstrated in CESNET
Operation demonstrated outside CESNET on University of
Washington (8th Annual Global LambdaGrid Workshop on 1
October 2008 at Seattle), CLM was located at StarLight and
managed remotely
Main CL devices: CLA (Optical Amplifier), CLS (Optical Switch),
CL-VMUX (Variable MUX), CL-ROADM (Reconfigurable Optical
Add/Drop Multiplexor), CLC (CD Compensator)

Connecting dispersed users to GOLEs
Suggested approach is based on dark fibres connecting end
users and GOLE via photonic (all-optical) lightpaths (i.e.
implemented without OEO conversions)
It was successfully demonstrated (but not yet fully published)
for example in GLIF2007 workshop in Prague as connection
between Charles University and GOLE Prague, used for all
demos
Photonic lightpath connected to GOLE Prague are available in
CESNET2 NREN and in CESNET Experimental Facility, including
CBFs
Commercially available transmission systems alows optical reach
of 10G photonic lightpaths about 1000 km now and extension to
about 2000 km is prepared, as well as upgrade to 40G
transmission rate

LTTx: Lightpaths To The x
FTTx development enables large change of network services,
see http://www.ftthcouncil.eu/
Openness to all service providers and low transmission latency
is crucial, see Herman Vagter: Fiber-from-the-home (as the
customer percieves him/herself to be the centre of the
universe), http://www.oecd.org/dataoecd/36/28/40460647.pdf
Lightpaths to home or company users will be very probably one
type of service on FTTx (LTTx is acronym suggested by speaker
here)
Lightpaths service to the office or home (including home
working) is enabling new applications and wider deployment
Experience from GLIF experiments using dedicated fibre last
miles are important for FTTx development
Development of many applications based on lambda services
depend on our ability to connect real end users in their office or
home

EU adopts law to raise telecom
competition
The European Parliament adopted measures to give consumers a
wider choice and less-costly services, see
http://www.iht.com/articles/2008/09/24/business/telecom.php
Proposal force telecommunication companies to run their network
and retail services as separate businesses to give competitors
easier access to their networks
From long term strategic point of view, it will help also to
deployment of Lightpaths services for the office or home

CESNET photonic fibre lighting
Fibre footprint 5 210 km


4 470km CESNET2 (including 1 050km of single fibre lines)
740km of CESNET EF (Experimental Facility)
Results: lambdas without OEO in CESNET2, 4 lines in CESNET
EF and 4 lines in CESNET2 are lit by open photonic devices, 5
other lines will be lit still in 2008, interoperability without OEO
achieved, single fibre bidirectional DWDM n x 10G is in
operation (about 40% of fibre pair lease cost savings)
Confirmation: Photonics approach to lighting is quite „green“:
saving energy, housing space, travelling to huts and costs

No easy life above 10G wavelenght rate
Interoperability on lambda level will be big issue in the future
(different modulation formats, filtering, etc.)
Legacy WDM systems usually strongly limits selections of
effective modulation formats (narrow band filtering is limitation
for alien lambdas)
Active collaboration and pre-procurement with vendors is
necessary
Each vendor has „the best solution for us“, we strongly need
vendor-independent knowledge verified by theoretical work and
experiments in real environment
What WDM we should ask for our fibre footprint (GEANT,
NRENs, MANs, campuses)?

Photonic (all-optical) services
From lab to real world
dark fibre Experimental Facility (EF) needed


user participation of EF is directed by experiments
EF can be used for experimental services to NREN (testing of EF
DWDM lines by real traffic of NREN)
deployment of photonic services in R&E networks
saving energy, housing space and cost (especially with
bidirectional single fibre transmission)
photonic experts able to work in R&E network environment
needed
federated and interoperable photonic services for R&E
upgrade of dark fibre lease to lit fibre lease (contracting
deployment of photonic technology by fibre provider, based on
our lighting project), with dedicated or shared fibre capacity
deployment of photonic services in ISP/enterprise networks

Network design for high speed
multidomain e2e services
Domains: GEANT, NRENs, MANs, campuses will be using different
DWDM equipment
OEO conversion needed for domain interconnection is expensive
(especially, if domains are small) and limits transmission speed
 Photonic Integrated Circuits (PIC) help in part only (PICs will
not be used in all domains)
How to achieve interoperability on optical level? How to achieve
lower power consumption and save space and costs? We need at
least:
 neutral FTTx (home run fiber available to any service
providers)
 knowledge of optics (what alien lambdas can domain accept?)
verified by experimentation (technology testing)
