White Rabbit (WR) is designed to compensate changes of the temperature of the physical medium (e.g. fiber). It has been tested and proven that such a compensation works (here) . However, since WR was presented to ITU-T in March 2012, the influence of WR devices’ temperature variation on the
synchronization performance of the system has been debated. The preparation of an article which describes the performance of the first deployment of WR-base system in the CERN Neutrino to Gran Sasso (CNGS) time transfer, was a very good excuse to perform environmental tests of White Rabbit.

The results of the performed temperature tests are included in Toruture Report
