Full title and description

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-34: Examinations and measurements - Attenuation of random mated connectors (IEC 61300-3-34:2009). This part specifies a repeatable procedure to characterise the statistical distribution and mean attenuation (insertion loss) observed when optical connectors are mated at random, and clarifies launch-condition considerations for multimode fibres.

Abstract

IEC 61300-3-34:2009 defines a standard test method for measuring the attenuation distribution and mean attenuation of randomly mated optical connectors. The procedure covers sample selection, measurement sequence, data treatment (statistical evaluation) and requirements for test fixturing and launch conditions, with particular attention to multimode fibre launch conditions compared with earlier editions.

Scope

This part of IEC 61300 gives the method required to measure the statistical distribution and the mean attenuation of optical connectors when specimens are mated at random. It is intended for use with both single‑mode and multimode connector types; the 2009 revision specifically updates guidance on launch conditions for multimode fibres. The standard is intended to produce comparable results between laboratories and production environments for qualification and quality control purposes.

Key topics and requirements

• Definition of sample size and random mating procedure to produce a representative statistical distribution of connector attenuation.
• Measurement sequence and repeatability requirements for insertion loss/attenuation readings.
• Data treatment and statistical evaluation methods (mean attenuation, distribution analysis, outlier handling).
• Requirements for test fixturing, reference connectors and calibration of test instruments.
• Specified launch-condition guidance, including revised considerations for multimode fibre launch conditions (to ensure comparable multimode results).
• Environmental and handling notes that can affect measurement repeatability (cleaning, mate/demate cycles, temperature control).

Typical use and users

Used by connector and transceiver manufacturers, independent test laboratories, quality/production engineers, telecommunications equipment vendors and standards/qualification bodies. Typical uses include production quality control, connector qualification testing, supplier acceptance testing and comparative laboratory studies of connector families.
