Bilateral Optical Power Meter Comparison Between NIST and CENAM*
نویسندگان
چکیده
We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Centro Nacional De Metrología (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. Measurements showed a largest difference of less than 3.4 parts in 10(3), which is within the combined expanded (k = 2) uncertainty for the laboratories' reference standards.

Bilateral Comparison of Dc Voltage References between Cenam and Nist
A comparison of Josephson Voltage Standards (JVS) between the National Institute of Standards and Technology (NIST) and the Centro Nacional de Metrología (CENAM) held at CENAM from 21 to 23 of March 2006 is reported. The comparison was made at the 10 V level by measuring four Zener references using the JVS of CENAM and the transportable Compact Josephson Voltage Standard (CJVS) of NIST. The dif...

متن کاملOptical Fiber Power Meter Calibrations at NIST
The optical fiber power meter (OFPM) is perhaps the most common type of test equipment used to support the development and implementation of optical fiber systems. To address the inherent metrology requirements, NIST has developed and implemented measurement services to help characterize these instruments [1]. These measurement services consist primarily of absolute laser power calibrations usi...
