Optical Fiber Power Meter Comparison Between NIST and NIM

摘要

We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and National Institute of Metrology (NIM-China). We report optical fiber-based power measurements at nominal wavelengths of 1310 nm and 1550 nm. We compare the laboratories’ reference standards by means of a commercial optical power meter. Measurement results showed the largest difference of less than 2.6 parts in 10³, which is within the combined standard (k = 1) uncertainty for the laboratories’ reference standards.
