International comparisons of optical fiber power measurements
Igor Vayshenker, David J. Livigni, Xiaoyu X. Li, John H. Lehman
We discuss the results of optical fiber power meter (OFPM) measurements at 1302 and 1546 nm made by NIST and six national measurement institutes (NMIs). We also describe transfer standards and the associated uncertainties. The comparisons show a reasonably good agreement between the participating laboratories, with relative differences that are within the standard (k=1) uncertainties.
