Paper Abstract

At first, this paper gives a brief description of the cryogenic radiometer used as standard for radiometric measurements at the Institut National de Metrologie (INM). After, it describes the procedure used to calibrate transfer detectors, for the measurements in the field of optical fiber telecommunications. This absolute calibration was performed at the laser diode wavelength of 1550 nm. The first results for three different detectors calibrated by comparison to INM cryogenic radiometer for the above wavelength shows that the uncertainty of the calibration is less than 0.5% at 1 (sigma) level and is about twice as good as the uncertainty given by the former extrapolation method used at INM.
