AB - Optical and radio frequency standards located in JILA and National Institute of Standards and Technology
(NIST) laboratories have been connected through a 3.45-km optical fiber link. An optical frequency standard
based on an iodine-stabilized Nd:YAG laser at 1064 nm (with an instability of ~4 x 10^(-14) at 1 s) has been
transferred from JILA to NIST and simultaneously measured in both laboratories. In parallel, a hydrogen
maser-based radio frequency standard (with an instability of ~2.4 x 10^(-13) at 1 s) is transferred from NIST to
JILA. Comparison between these frequency standards is made possible by the use of femtosecond frequency
combs in both laboratories. The degradation of the optical and rf standards that are due to the instability in
the transmission channel has been measured. Active noise cancellation is demonstrated to improve the transfer
stability of the fiber link. © 2003 Optical Society of America
