The Czech-Austrian experiment focused on comparing the time of atomic clocks in Prague and Vienna using a fiber optic link.

The uncertainty of the measurement was less than one nanosecond. No one else has probably conducted such an experiment with international transport of time using fiber optics at the same distance and with comparable accuracy. This experiment indicated for which real-time applications the internet can be used in the future.

IPE carries out fundamental and applied research in the scientific fields of photonics, optoelectronics and electronics. In these fields, IPE generates new knowledge and develops new technologies.
