Optical TelecommunicationsOptical telecommunication is the use of light (opticalfrequency domain) to transmit information: Wavelengths 0.85 μm to 10 μm (30-353 THz) Alternative to the increasing scarce RF spectrum. Optical communication offers an unregulated, extremelybroad spectrumESA UNCLASSIFIED - For Official UseESA 12/07/2017 Slide 5

World Market Demand and Opportunities Fixed broadband (e.g. HTS - High throughput satellite) and mobile market (e.g.aeronautical, maritime and land) are pushing the satcom capacity demand. This capacity needs to be used where needed: Traffic Flexibility in terms ofbandwidth allocation and coverage Secure communication and service immuneto interferences and jammers Lower frequencies under threat for satcomapplications. Conventional RF frequency spectrumbecomes a scarce resource.Optics is a natural step to unleash resources(bandwidth, high capacity) and fulfil thisgrowing demand.ESA UNCLASSIFIED - For Official UseESA 12/07/2017 Slide 7
Demand and Opportunities Expressed byEuropean Satellite Operators All major European Satellite Operators have expressed interest in Proof-ofConcept Optical Technology as a stepping stone into its adoption in theiroperational satellite fleet. Interest expressed in using optical communications for GEO-ground, GEO-GEO,GEO-LEO, MEO-MEO, and LEO/MEO-ground. Different motivational factors: Freeing RF spectrum for user links (optical feeder links). Data security to deliver to certain users (optical downlink). Communication between space assets (inter-satellite links).ESA UNCLASSIFIED - For Official UseESA 12/07/2017 Slide 8
Where Optical Technologies Can Make aDifference: Opportunities and ChallengesOptical Link High data rate ( 100 Gbps) with smalltelescopes Less mature technology requires R&Deffort Abundant unregulated bandwidth andeffective use of frequency resources Higher precision laser pointing (butdemonstrated) Immunity to interception, jamming,interferers and piracy Lack of common communicationstandards Terrestrial optic technology enable spacemarket (investment already made)For links through the atmosphere: Reduced size/power of ground terminals Potential to reduce the number ofgateways for HTS architecturesESA UNCLASSIFIED - For Official Use Cloud blockage requires a network ofconnected ground stations at suitablelocations Atmospheric conditions (scintillation,beam wander, phase coherence ) Eye safety requirementsESA 12/07/2017 Slide 9

Conclusions (1/2) Optical communication is still a brand new solution with unique, not yet unleashed potential The DRAFT roadmap has identified potential applications and the main challenges. Excellentresults have already been achieved. Europe is currently in the lead for optical inter-satellite communications, however: Non-ESA countries, USA & Japan in particular, are moving quickly, targeting full opticalsystems within 10 years. ESA is implementing and running activities to increase the TRL level for keytechnologies/products in ScyLight, ARTES C&G/AT and TRP. ESA needs to undertake a substantial system study to analyse technical requirements,assess the feasibility ESA needs to proof the maturity of the technology and define solid solutions Optical technologies cover the entire value chain: an opportunity for small and medium-sizeenterprises. .ESA UNCLASSIFIED - For Official UseESA 12/07/2017 Slide 29

Interest expressed in using optical communications for GEO-ground, GEO-GEO, GEO-LEO, MEO-MEO, and LEO/MEO-ground. Different motivational factors: Freeing RF spectrum for user links (optical feeder links). Data security to deliver to certain users (optical downlink). Communication between space assets (inter-satellite links).
