Abstract

Optical and radio frequency standards located in JILA and NIST laboratories have been connected through a 6.9 km roundtrip optical fiber link. An optical frequency standard based on an Iodine stabilized Nd:YAG laser at 1064 nm with an instability of {difference of} 4 x 10¹⁴ at 1 second has been transferred from JILA to NIST and simultaneously measured in both labs. In parallel, a hydrogen maser-based radio frequency standard with an instability of -2.4 x 10^-13 at lsecond was also transferred from NIST to JILA. Comperison between these frequency standards was made possible by the use of femtosecond frequency combs in both laboratories. The degradation of the optical and RF standards due to the instability in the transmission channel has been measured. Active noise cancellation is thermonstrated to improve the stability of the fiber link.
