  3. 3. Why are optical T/F services so popular?
    Dr Harald Schnatz (PTB)
    09/03/2021, 13:10

    This presentation aims to overview why there is a such a worldwide enthusiasm for new optical Time and Frequency services. Dr Harald Schnatz (PTB) will present the historical background of these new services and why they could be so usefull in scientific, societal and economic domains.

  4. 4. Time and Frequency services for end-users
    Mr Jani Myyry (CSC/Funet)
    09/03/2021, 13:30

    While the number of potential T/F end-users keeps growing, several techniques have been deployed (optical carrier techniques using different wavelength, modulation techniques, unidirectional, bidirectional...) Jani Myyry will give us an overview of the existing techniques and help us understand the main differences (advantages and drawbacks) in different scenarios.

  5. 5. Time and frequency requirements for radio astronomical interferometry
    Mr Paul Boven (JIVE "Joint Institute for VLBI ERIC")
    09/03/2021, 13:50

    Interferometry is a technique in radio astronomy where the signals of multiple radio telescopes are combined, creating a single virtual telescope with a much improved resolution. This requires the transport of large amounts of data, and the distribution of a very stable reference frequency and timing signal to each of the receptors. In this presentation I will highlight several examples and...

  6. 9. T&F Research and Innovation projects (CLONETS-DS, TIFOON)
    Mr Wojbor Bogacki (PSNC)
    09/03/2021, 14:20

    CLONETS-DS aims to establish a pan-European time and frequency reference system as a European Research Infrastructure to serve the science community. It will follow the recommandations of TiFOON's technical project which will advance fibre-based frequency transfer capabilities in Europe towards a universal tool for time and frequency metrology by developing combined time and frequency...

  7. 6. Current T&F situation in NREN networks
    Dr Josef Vojtech (CESNET)
    09/03/2021, 14:30

    Optical Time and Frequency networks do already exist in the NREN community. In this presentation, Josef Vojtech (CESNET) will present some existing setups underlying their differences, choices of architecture and objectives. We hope this will encourage NREN that are not familiar with optical Time and Frequency to get in touch with this new type of fibre usage.
