We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Centro Nacional De Metrologia (CENAM-Mexico). Open beam (free field) and optical-fiber-based measurements at wavelengths of 1302 nm and 1546 nm are reported. Both laboratories reference standards were compared by means of a temperature-controlled optical trap detector. Measurement results showed a largest difference of less than 3.4 parts in 103, which is within the combined expanded (k=2) uncertainty for the laboratories reference standards.
