• Elizabeth Donley - Time and Frequency Division Chief, NIST

The Time and Frequency Division of the National Institute of Standards and Technology (NIST) provides a variety of time and frequency metrology services and research. One of the Division’s responsibilities is to realize and distribute UTC(NIST). Adding to NIST’s current methods for time distribution, NIST has made available a new calibration service that distributes UTC(NIST) over optical fiber. The initial goal is to realize an accuracy of 1 microsecond in a remote location, with the eventual improvement to 100 ns or better. An update on the status of this new service will be presented.
