EN 61754-6-100:2016/prA1:2026 is an amendment in the fibre optic connector interface series for the Type MU connector family. It updates the simplified receptacle MU-PC connector interfaces and the IEC references used to describe and apply them. Engineers, manufacturers, test laboratories, quality teams, and buyers use it when they need the MU interface definition to match the current supporting standards.

What does EN 61754-6-100:2016/prA1:2026 specify?

EN 61754-6-100:2016/prA1:2026 specifies amendments to the interface definition for the Type MU connector family, with a focus on simplified receptacle MU-PC connector interfaces. It is a short document that revises references and interface-related notes rather than introducing a full new structure.

The amendment is organized into a foreword, normative references, description, interfaces, and bibliography. In practice, that means the document is mainly about keeping the MU interface specification aligned with current IEC references and current wording in the interface tables and figure notes.

What are the key requirements of EN 61754-6-100:2016/prA1:2026?

The main substance of EN 61754-6-100:2016/prA1:2026 is the set of updates it makes to references and interface wording in Clauses 2 to 4. These updates matter because they tell users which companion standards to apply when specifying, checking, or comparing MU connector interfaces.

• Clause 2 updates the normative references. It replaces IEC 61754-6:2013 with IEC 61754-6, replaces IEC 61755-3-1 with IEC 61755-3 (all parts), and adds IEC 63267-3 (all parts). In practice, anyone applying the MU interface needs to use the current family standard and the current optical-interface series behind it.

• Clause 3 updates the descriptive cross-reference in item f). The text now points to IEC 61754-6 instead of IEC 61754-6:2013. This keeps the description aligned with the current part designation used across the series.

• Clause 4 updates Table 1, footnote a. The footnote now points to IEC 61754-6. That matters when a reader is tracing the table back to the governing Type MU connector family standard.

• Clause 4 updates Table 2, footnotes b, c, and d. These footnotes now point to IEC 61754-4. For users, this keeps the related interface notes connected to the current connector interface part they are meant to follow.

• Clause 4 revises Table 4, row CK. The amendment changes the surface-finish wording from a grade-based notation to an Ra-based roughness designation. In practice, this affects how the relevant surface condition is specified and checked in drawings, inspection documents, or supplier records.

• Clause 4 updates the references above Figure 3 and in Table 6. The text now points to the IEC 61755-3 series and the IEC 63267-3 series. That tells users which optical-interface series to consult for the relevant physically contacting fibre types.

• The bibliography removes IEC 61755-6-1 and its footnote. This keeps the supporting references consistent with the revised text and avoids relying on a withdrawn supporting citation.

What terms does EN 61754-6-100:2016/prA1:2026 define?

• MU connector family - The connector family covered by Part 6-100 of the IEC fibre optic connector interface series.
• MU-PC connector interfaces - The MU connector interfaces identified as physically contacting (PC) interfaces.
• Simplified receptacle - The receptacle variant used for the MU-PC connector interface in this part.
• Physically contacting fibres - Fibres intended to make physical contact in the connector interface.
• Dispersion unshifted single-mode physically contacting fibres - The single-mode fibre type tied to the IEC 61755-3 series.
• Enhanced macro bend multimode fibres - The multimode fibre type tied to the IEC 63267-3 series.
• Ra - The surface roughness parameter used in Table 4 to describe the revised finish notation.

Who uses EN 61754-6-100:2016/prA1:2026?

EN 61754-6-100:2016/prA1:2026 is used by connector designers, fibre optic component manufacturers, and suppliers of passive components who need to define or verify MU interface compatibility. It is also used by test laboratories and quality teams that check interface details against the correct IEC references.

Buyers, procurement teams, and system integrators use it when they need to specify the MU connector family clearly in purchasing documents or product requirements. It is relevant in fibre optic interconnecting devices and passive components work, especially where mating interfaces and optical-interface references must stay aligned.

What changed in EN 61754-6-100:2016/prA1:2026 from the previous edition?

This amendment updates the reference set and refreshes the interface-related cross-references in the MU connector family part. The changes stated in the document are:

• IEC 61754-6:2013 is replaced by IEC 61754-6.
• IEC 61755-3-1 is replaced by IEC 61755-3 (all parts).
• IEC 63267-3 (all parts) is added.
• The description, Table 1, Table 2, Figure 3 text, and Table 6 are aligned with the new references.
• Table 4, row CK, is updated to use an Ra roughness designation.
• IEC 61755-6-1 is deleted from the bibliography.

Which standards are used with EN 61754-6-100:2016/prA1:2026?

Standard	What it contributes
IEC 61754-6	The main Type MU connector family interface standard referenced throughout the amendment.
IEC 61755-3 (all parts)	Optical interface parameters for dispersion unshifted single-mode physically contacting fibres.
IEC 63267-3 (all parts)	Optical interface parameters for enhanced macro bend multimode fibres with 50 µm core diameter.
IEC 61754-4	The updated reference used in Table 2 footnotes for related connector interface notes.

What does the EN 61754-6-100:2016/prA1:2026 document contain?

EN 61754-6-100:2016/prA1:2026 contains a foreword, a normative references clause, a short description update, interface updates, and a bibliography change. The technical content is concentrated in Clause 4, where Table 1, Table 2, Table 4, Figure 3 text, and Table 6 are revised.

The document is useful for design control, specification writing, interface checking, and supplier communication. It tells users which current IEC standards to consult for the MU connector family and the related optical-interface definitions.

13 FOREWORD
14 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
15 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
16 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
17 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
18 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
19 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
20 in the subject dealt with may participate in this preparatory work. International, governmental and non -
21 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
22 with the International Organization for Standardization (ISO) in accordance with conditions determined by
23 agreement between the two organizations.
24 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
25 consensus of opinion on the relevant subjects since each technical committee has representation from all
26 interested IEC National Committees.
27 3) IEC Publications have the form of recommendations for international u
