Time transfer using an asynchronous computer network: Results from three weeks of measurements
Paper i proceeding, 2007
We have performed a time transfer experiment
between two atomic clocks, over a distance of approximately 75
km using an 10 Gbit/s asynchronous fiber-optic computer
network. The time transfer was accomplished through passive
listening on existing data traffic and a pilot sequence in the SDH
bit stream. In order to assess the fiber-link clock comparison, we
simultaneously compared the clocks using a GPS carrier phase
link. The standard deviation of the difference between the two
time transfer links over the three-week time period was 243 ps.
