10 Innovative Photonic Applications and Services in NRENs High speed data networks are almost everywhere. The only medium capable to satisfy constantly growing needs for more capacity on long distances is fibre this is well known. High speeds (400Gbps, 1Tbps) cannot solve all challenges. Low and stable latency are important. Collaborative efforts like music and dance on different continents. KREONET Workshop 2017 Nov 30th,

11 Innovative Photonic Applications and Services in NRENs New applications: Accurate time, Ultra stable frequency transfers. Fibre sensing applications pressure, temperature, position sensors, biosensors, intrusion detection: humans (e.g. break-ins), animals. Time/frequency/sensing applications are really here non data. But: data transmissions are based on coherent detection principles and use multilevel phase modulations like DP-QPSK and DP-16QAM. 1G and 10G still used of course. Such photonic signals must be transmitted in the same fibre as coherent high speed signals for economic reasons. Issue to be solved: amplitude and phase modulated signals and (rather) different powers. KREONET Workshop 2017 Nov 30th,

12 Innovative Photonic Applications and Services in NRENs Why time/frequency? Quantities we can measure with highest accuracy tiny effects are measurable. Geodesy, seismology, astronomy... Are the fundamental constants really constant? Tests of special and general relativity, Higgs boson, gravitational waves,... Optical fibre is a good candidate for a distances of few 1000s of km RF methods (GNSS, TWSTFT) reaching their limits KREONET Workshop 2017 Nov 30th,

13 Time and Frequency Services Development started in interconnection of UFE (Institute of Photonics and Electronics) in Prague BEV (Federal Office of Metrology and Surveying) in Vienna CESNET becomes the central point km line Prague-Brno, single medium bidirectional propagation Parallel transmission of time and frequency 2016 ELI (Extreme Light Infrastructure) Upgraded to CLA BiDi (Czech Light Amplifier Bidirectional) - security risks significantly limited (hacker attacks) KREONET Workshop 2017 Nov 30th,

21 Self Protecting Infrastructure What is it A new service that is rapidly evolving and very desirable. Active monitoring of all vibrations near a fibre cable. How it can be done Heavy equipment digging near a fibre will shake a fibre cable before break it. Mostly based on evaluation of phase/polarization/ backscatter of the light. Why is it important Enabling proactive protection In combination with SDN and NetOS allows to reduce network outage times. Using existing routes, including those with active data traffic.
