Optical-Fiber Power Meter Comparison between NIST and LAMETRO



Johnny Jimenez, Maria Ugalde, John H. Lehman, Igor Vayshenker


We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Laboratorio de Metrologia, Instituto Costarricense de Electricidad (LAMETRO-ICE, COSTA RICA) for optical fiber-based power measurements at wavelengths of 1310.0 nm, 1550.15 nm, and 1625.0 nm. We compare the laboratories' reference standards by means of a commercial temperature-controlled optical fiber power meter. Measurement results showed the largest difference of less than 5.8 parts in 103, which is within the combined standard (k=1) uncertainty for the two laboratories' reference standards.
