IEC 61315:2005

Fibre optic power meters are designed to measure optical power from fibre optic sources as accurately as possible. This capability depends largely on the quality of the calibration process. This International Standard standardizes all of the steps involved in the calibration process: establishing the reference conditions, carrying out the calibration, calculating the uncertainty, and reporting the uncertainty, the reference conditions, and the traceability. It also creates a standardized type of power meter specification, which will make it easier to compare power meters from different vendors.

IEC 61315:2019 is applicable to instruments measuring radiant power emitted from sources that are typical for the fibre-optic communications industry. These sources include laser diodes, light emitting diodes (LEDs) and fibre-type sources. Both divergent and collimated radiations are covered. This document defines the calibration of power meters to be performed by calibration laboratories or by power meter manufacturers. This third edition cancels and replaces the second edition published in 2005. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of terms and definitions; b) update of 5.1, including Table 1 (new type of source); c) update of Annex A; d) addition of Annex B on dB conversion.
