Abstract: We describe NIST measurement services for the calibration of optical fiber power meters. To augment the absolute power measurements NIST provides nonlinearity, spectral responsivity, and uniformity measurements. We explain the measurement standards, systems, methods, and uncertainties related to the NIST calibration services for optical fiber power meter. Fiber connector issues are briefly described. Since optical fiber power meters (OFPMs) are a very common type of optical test equipment, NIST has developed and implemented measurement services to help characterize these instruments.1 These measurement services consist of absolute power calibrations using either parallel-beam or optical fiber/connector configurations. In addition, NIST provides measurements of nonlinearity, spectral responsivity (based both on tunable lasers and white-light sources), and uniformity. Calibrations are available at the three principal wavelength regions used by the optical fiber telecommunications industry, 850, 1300, and 1550 nm. Other optical power meter users (e.g., compact-disc player manufacturers and users of erbium-doped fiber amplifiers) are additionally interested in 670, 780, and 980 nm. We have also incorporated these wavelengths into our absolute power calibration program as well.
