Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-14: Examinations and measurements - Error and repeatability of the attenuation settings of a variable optical attenuator
IEC 61300-3-14:2025 provides a method to measure the error and repeatability of the attenuation value settings of a variable optical attenuator (VOA). There are two control technologies for VOAs: manually controlled and electrically controlled. This document covers both VOA control technologies and also both single-mode fibres and multimode fibres VOAs. For electrically controlled VOAs, the hysteresis characteristics of attenuation are sometimes important. The hysteresis characteristics can be measured as stated in Annex B. This fourth edition cancels and replaces the third edition published in 2014.This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) addition of IEC 61315, Calibration of fibre-optic power meters as normative reference;b) addition of Clause 3 containing terms, definitions and abbreviated terms;c) addition of notes for permission of repeatability definition with 2σ;d) correction of error in Figure 1 a) and Figure 1 b);e) addition of a clear statement on EF launch condition requirement for MM source;f) change of “Detector” to “Power meter”;g) combination of Clause 7 and Clause 8 into a new Clause 8 titled “Details to be specified and reported”;h) addition of uncertainty considerations in Clause 7;i) correction of error in Formula (B.3).

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-14: Examinations and measurements - Error and repeatability of the attenuation settings of a variable optical attenuator
IEC 61300-3-14:2014 provides a method to measure the error and repeatability of the attenuation value settings of a variable optical attenuator (VOA). There are two control technologies for VOAs, manually controlled and electrically controlled. This standard covers both control technologies of VOAs and also covers both single-mode and multimode fibre VOAs. This third edition cancels and replaces the second edition published in 2006 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - title modification replacing the word "accuracy" by "error"; - inclusion of the distinction of manually and electrically controlled variable optical attenuators in the Scope; - revision of clauses for apparatus and details to be specified to harmonize with other standards in the IEC 61300 series; - addition of "the maximum deviation of attenuation from setting" to the clause for calculation; - addition of "measurement method of hysteresis characteristics" in Annex B. Keywords: attenuation value settings, variable optical attenuator (VOA)
