The 1000 km White Rabbit link under test by MIKES and CSC (that operates FUNET) in Finland is actually quite a system as Mr. Merimaa from MIKES explains:

The WR-master is actually referenced to UTC (MIKE), so that we have (some kind of) representation of UTC (MIKE) in Kajaani even now! And not just a second, but the time of day as well.

The WR-slave at Kajaani is now being operated with remote desktop using the data transfer capability of the WR-link. The same link will be used to access the Cs-clock, time-interval counter, and the GTR51 receiver. We are now setting up the remote access to instruments before we transfer them to Kajaani, but in principle this should work.

Another thing maybe worth noting, is that the link actually goes through a WR-switch at CSC Espoo site (0.5 km from us). I we are successful, this switch will be a hub for other time links within the FUNET network.

We have also measured the performance of a loopback link consisting of
MW-master (MIKES) - 0.5 km - WR-switch (CSC) - 0.5 km - WR-slave (MIKES)@
and did not find any drifts - impressive!
