20 Dynamic Photonic Testbed Allows sharing of resources on the photonic layer optical fibres, de/multiplexers, optical amplifiers, optical switches, etc. Inspired by the principles of SDN and Testbed as a Service Flexible, easily and quickly reconfigurable, real optical infrastructure Provides services for third parties Users/experimenters

21 Dynamic Photonic Testbed Prepared application of Dynamic Photonic Testbed Technologies for measurement and analysis OSA - Optical spectrum analyzer for measuring the wavelength and optical power PM Power meter for measuring the optical power OTDR - Optical time-domain reflectometer, method for measurement and analysis of optical route (estimate fibre length and overall attenuation including connections, macro-bends, etc.) Measurement of chromatic dispersion CD and polarization mode dispersion PMD Access to special scientific equipment (eg. telescope or spectroscope) We welcome anyone interested in the joint development of PT and its applications

22 Dynamic Photonic Testbed Laboratory demo Two independent optical routes Optical fibre spools G. 300 km + dispersion compensators E.g. for data transmission Optical fibre spools G. 300 km E.g. for bidirectional transfer accurate time and frequency T/F CLS CzechLight Switch Optical switch serves as a central point for connecting/disconnecting optical components (Mux/Demux, optical fibre amplifiers and compensators,...) CLM CzechLight Multicast Switch Optical multicast switch which serve as a "universal monitor port" for measuring equipment Located in the CESNET laboratory

24 Long Haul Testbed Consisted of a total fibre length km On one shelf is 200 km length fibre (type G.652D) km of optical fibres in one rack Big attenuation is compensated by 30 EDFA amplifiers Czech Light, serving as a booster, inline and preamplifier Last tests: 2x200G transmission over km length, and 200G transmission over km length

25 Experimental Facility 306 km Higher utilization of available spectrum Sharing of Dark Fibres Sharing of optical route by more transfer systems in C-band, L-band, BiDi and other photonic services Sharing of the C-band by photonic services for transmission of accurate time and stable frequency Bidirectional 800 GHz channel (green)
