SIST EN IEC 61300-2-2:2026 is a CENELEC European Standard that adopts IEC 61300-2-2:2026 for fibre optic interconnecting devices and passive components. It specifies a mating durability test, meaning repeated mating and un-mating cycles used to check optical performance and mechanical wear in connectors and related devices. Manufacturers, test laboratories, and quality or reliability teams use it when they need a common way to verify how a device behaves under normal use.
What does SIST EN IEC 61300-2-2:2026 specify?
SIST EN IEC 61300-2-2:2026 specifies a basic test and measurement procedure for evaluating the effects of repeated mating and un-mating on fibre optic connectors or other interconnecting devices. The test examines changes in attenuation and return loss, and it also checks for mechanical degradation after cycling.
The document is organized into clauses on scope, normative references, terms and definitions, general description, apparatus, procedure, severity, and details to be specified and reported. It also includes Annex ZA for the European normative references, plus figures showing the two main test configurations.
What are the key requirements of SIST EN IEC 61300-2-2:2026?
SIST EN IEC 61300-2-2:2026 requires the device under test (DUT) to be cycled through repeated mating and un-mating under normal usage conditions. In practice, that means the test is meant to simulate everyday connector use rather than an artificial laboratory-only sequence.
Clause 4 defines the test action: successive mating and un-mating cycles are applied to the DUT. If more than one coupling mechanism is involved, each cycle is carried out with all mechanisms properly engaged, so the test reflects the full connection state.
Clause 5.1 and 5.2 cover the fixture and force application. The DUT is held in alignment as needed, and mating force is normally applied by hand unless the manufacturer specifies another method. If another method is used, the force or torque and the method must be reported.
Clause 5.3 and 6.2 link the test to optical measurement and initial checks. Monitoring equipment from IEC 61300-3-3 is used during the test, while initial visual inspection follows IEC 61300-3-1 and initial measurements follow the relevant IEC 61753 series performance standard or IEC 62005 series reliability document.
Clause 6.3 defines the cycling sequence. A baseline optical measurement is taken before cycling, then each un-mating and mating pair counts as one cycle. The minimum time between cycles is 3 s, and for a plug-adaptor-plug configuration only one plug is cycled.
Clause 6.4.1 and 6.4.2 require monitoring of attenuation, return loss, or both during the test. Measurements are recorded after every mating, and cleaning may be done according to the manufacturer’s instructions or IEC TR 62627-01. If performance goes outside the required limit, inspection, cleaning, and re-measurement may be repeated up to three times.
Clause 6.4.3 requires a final visual examination. The sample is checked for broken or worn parts, poor engagement or separation, seal damage, and interface damage such as breakage, chipping, or scratching.
Clause 7 and Clause 8 control severity and reporting. The severity is linked to performance categories, and the test report must state the DUT characteristics, the coupling mechanism tested, the chosen severity, the measurement and pass/fail requirements, and any deviations.
What terms does SIST EN IEC 61300-2-2:2026 use?
SIST EN IEC 61300-2-2:2026 uses these key terms in the test procedure:
- Device under test (DUT) - the connector or interconnecting device being subjected to the mating durability test.
- Mating durability - the ability of the DUT to withstand repeated mating and un-mating while maintaining acceptable performance.
- Attenuation - the loss measured during optical transmission, monitored to see whether connector performance changes during cycling.
- Return loss - the reflected optical loss monitored alongside attenuation during the test.
- Plug-adaptor-plug configuration - a test setup in which only one plug is subjected to repeated cycles against an adaptor.
- Plug-receptacle configuration - a test setup where a plug is cycled against a receptacle.
- Severity - the selected test level, expressed through the number of cycles for the relevant performance category.
Who uses SIST EN IEC 61300-2-2:2026?
SIST EN IEC 61300-2-2:2026 is used by manufacturers of fibre optic interconnecting devices and passive components, especially when they need to qualify connector designs for durability. Test laboratories and certification bodies use it to run repeatable mating endurance tests and record the optical and visual results.
Quality, reliability, and product engineering teams use it when comparing performance categories, setting test severities, or writing test plans linked to IEC 61753 or IEC 62005. It is also relevant to buyers and specifiers who need a shared test language for connector endurance.
What changed in SIST EN IEC 61300-2-2:2026 from the previous edition?
SIST EN IEC 61300-2-2:2026 supersedes EN 61300-2-2:2009 and its amendments and corrigenda, and it is identified as a technical revision. The stated changes are:
- the test is defined for a plug-receptacle configuration as well as a plug-adaptor-plug configuration
- measurement condition B is deleted
- one measurement condition is defined
- performance categories are added to the severities
- new severity levels are introduced for connectors and hardened connectors
- new cleaning criteria are added for the mating durability test
- performance category E is deleted
Which standards are used with SIST EN IEC 61300-2-2:2026?
SIST EN IEC 61300-2-2:2026 refers to these publications in the test procedure and European reference mapping:
- IEC 61300-1 - gives the general rules and guidance used for preconditioning and atmospheric conditions.
- IEC 61300-3-1 - provides the visual examination method used before and after the test.
- IEC 61300-3-3 - gives the active monitoring method for attenuation and return loss during cycling.
- IEC 61753 series - provides the performance standard used to set measurement requirements and pass/fail limits.
- IEC 62005 series - provides reliability documents that can also define measurement and acceptance requirements.
- IEC TR 62627-01 - provides connector cleaning methods referenced for in-test inspection and cleaning.
What does the SIST EN IEC 61300-2-2:2026 document contain?
SIST EN IEC 61300-2-2:2026 contains the test setup, apparatus guidance, procedure, severity selection, and reporting requirements for mating durability testing. It includes two figures showing the plug-adaptor-plug and plug-receptacle configurations.
The document also includes a table of recommended severity values and a bibliography. Annex ZA maps the cited international publications to their European counterparts, which helps users find the correct companion standards for testing and acceptance.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible f
