IEC 61300-3-4 Ed. 4.0 b:2023

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-4: Examinations and measurements - Attenuation

IEC 61300-3-4:2023 is available as IEC 61300-3-4:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61300-3-4: 2022 describes the various methods available to measure the attenuation of optical components. It is not, however, applicable to random mate attenuation measurements as described in IEC 61300-3-34 and IEC 61300-3-45 nor for attenuation measurements of dense wavelength division multiplexing (DWDM) devices as described in IEC 61300-3-29. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
 a) addition of Clause 3 containing terms, definitions and abbreviated terms;
 b) addition of a new LSPM measurement method, insertion method (D);
 c) addition of Annex A describing attenuation measurement of multicore fibre;
 d) changed reference test method to insertion C and alternative test method to substitution or insertion D for power meter and type 4 DUT.
