First Field Trial of the Frequency Transfer System with Passive Stabilization Scheme

In this paper we reports on a stable radio frequency (RF) dissemination system via optical fiber. The phase variations caused by fluctuations of the delay length are passively canceled out. The devices of transmitting site and receiving site are integrated into two prototype modules. After transmitted over 80 km commercial telecom fiber link, the measured fractional frequency instability (Allan deviation) of 2.4 GHz RF signal is 7.9×10^-17 for 10000 s averaging time.
