Highly stable optical frequency transfer
|Coordinator||RISE Research Institutes of Sweden AB - SP Mätteknik, Borås|
|Funding from Vinnova||SEK 1 078 000|
|Project duration||January 2016 - June 2018|
Purpose and goal
The aim of the project is to develop a reliable optical time and frequency transfer, where the technology is compatible with existing fiber infrastructure for communication. The goal is to create redundancy for critical functions of the society, industry, the financial sector, the energy industry and to strengthen research at Swedish universities and colleges. The goals have largely been met while new challenges have arisen due to the development of new fiber-based communication systems.
Expected results and effects
The project has resulted in enhanced knowledge of current and future fiber optic communication systems and how they can be used in a refined manner to strengthen redundancy to society and business. The research is successful, but there are still pieces that have not been resolved. An important effect is that the society´s needs for redundancy and time and frequency has been strengthened and charted. New systems for fiber based time and frequency distribution have been developed.
Planned approach and implementation
The planning on which the project was granted was well defined but failed due to external circumstances such as SUNET´s reconstruction of the fiberoptic network and switching technology for communication. That change led to delays and the project was extended. Moreover, the project has been implemented according to the new planning. The result is beyond expectation since it has resulted in 5 publications and a completed Master degree project together with Lund University.
