This network would connect a number of research facilities and the National Measurement Institute (NMI), allowing long-range comparison of frequency standards to high precision and providing reference signals for a wide range of applications. First results for transfer in the laboratory achieve a fractional frequency stability of 7×10⁻¹⁷ at an averaging time of 10⁴ s for the distribution of an 80 MHz radio frequency signal. We present details of the technique used to cancel noise introduced by the fibre, describe the all-digital radio-frequency phasemeter used to characterise performance, and outline plans for the further development of the network. 2012-06-04T20:40:06.880Z ]]> http://www.researchonline.mq.edu.au/vital/access/manager/Repository/mq:19497 We present a novel optical fiber-based radio-frequency distribution system that incorporates low-cost commercially available components. It has a fractional frequency stability of 7×10⁻¹⁷ (averaged over 10⁴ s) for distribution of an 80-MHz signal. 2012-05-30T09:51:37.288Z ]]>
