NIST optical fiber power measurements: intramural and international comparisons
Igor Vayshenker, John H. Lehman, David J. Livigni, Joshua A. Hadler
We discuss the results of intramural comparisons of NIST laser and optical fiber power meter (OFPM) measurements, and the results of OFPM comparisons between NIST and three National Measurement Institutes (NMIs). We also describe transfer standards, measurement systems and the associated uncertainties that we used in these comparisons. The comparisons show a reasonably good agreement between the participating laboratories, with relative differences that are within the combined standard uncertainties.
