- **Long Distance White Rabbit**: For both the SKA and the ASTERICS
|
|
|
|
project, we study how the stability of a WR link is affected by
|
|
|
|
factors like wavelength, temperature and fiber type. The SKA is a
|
|
|
|
future radio telescope about to be constructed in semi-desert areas
|
|
|
|
in South Africa and Australia, where WR will be used for time
|
|
|
|
transfer on overhead fiber links of up to 173km. In the ASTERICS
|
|
|
|
project, we research the use of WR for long distance frequency
|
|
|
|
transfer over public fiber. We show how the WR signal can co-exists
|
|
|
|
with an existing DWDM infrastructure, and aim to get close to
|
|
|
|
H-maser performance over a link of up to 165km, to provide a
|
|
|
|
reference signal to the LOFAR and Dwingeloo radio telescopes.

|
WhiteRabbit Link**: As a premise to deployment of White Rabbit over
|
|
|
|
legacy active optical telecommunication networks, we report on the
|
|
|
|
frequency stability and dissemination using the White Rabbit
|
|
|
|
technology over an in-lab cascaded unidirectional 500km fiber link
|
|
|
|
set-up. We use White Rabbit equipment improved in collaboration with
|
|
|
|
SevenSol and with support of the WR community, and show short term
|
|
|
|
frequency
|
|
|
|
stability of 2·10<sup>-12</sup> averaging down to 4·10<sup>-15</sup>
|
|
|
|
after 200000 s of integration time. No frequency shift is observed
|
|
|
|
within the statistical error bars.
