SIST EN 61754-6-100:2016/oprA1:2026 is a SIST standard for fibre optic connector interfaces in the Type MU connector family, specifically the simplified receptacle MU-PC connector interfaces. It amends the MU connector interface part by updating referenced IEC documents and selected interface tables, so designers, manufacturers, test labs, and specifiers can keep MU-PC interface documentation aligned with the current IEC framework.

What does SIST EN 61754-6-100:2016/oprA1:2026 specify?

SIST EN 61754-6-100:2016/oprA1:2026 specifies Amendment 1 to the Part 6-100 MU connector interface document. Its focus is the Type MU connector family and the simplified receptacle MU-PC connector interfaces, with the technical content centered on updated references and interface wording.

The document is organized into a foreword, Clause 2 on normative references, Clause 3 on Description, Clause 4 on Interfaces, and a bibliography. In practice, that means the amendment tells users which companion IEC documents to apply and where the interface tables and notes are being revised.

What are the key requirements of SIST EN 61754-6-100:2016/oprA1:2026?

This amendment mainly updates the standards that the MU-PC interface part depends on, and it aligns cross-references in the interface clauses. For users, the practical task is to check that drawings, notes, and conformity documents point to the current IEC parts.

• Clause 2 updates the normative references. IEC 61754-6:2013 is replaced by IEC 61754-6, and IEC 61755-3-1 is replaced by IEC 61755-3 (all parts). This matters because the MU family and the optical-interface parameters must be read against the current series.
• Clause 2 adds IEC 63267-3 (all parts). This brings in the connector optical interface parameters for enhanced macro bend multimode fibres with physically contacting 50 µm core diameter fibres. In practice, users working with those fibre types need to apply the new companion series.
• Clause 3 updates the description cross-reference. The description now points to IEC 61754-6 instead of the older edition reference. This keeps the descriptive text aligned with the current base part.
• Clause 4 revises Table 1 and Table 2 footnotes. The footnotes are updated to the current IEC connector-family references, including IEC 61754-6 and IEC 61754-4. That helps keep interface drawings and related notes consistent across linked connector parts.
• Clause 4 changes the CK entry in Table 4. The surface-finish notation for that row is updated. For manufacturers and inspectors, this means the interface finish is expressed with the revised wording and should be reflected in technical files.
• 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 instead of single-part references. This matters when checking optical interface parameters for design or procurement.
• The bibliography deletes IEC 61755-6-1. Users maintaining internal standards lists should remove that citation from MU-PC interface references.

What terms does SIST EN 61754-6-100:2016/oprA1:2026 define?

• Type MU connector family - the MU fibre optic connector family covered by Part 6-100.
• simplified receptacle - the receptacle form used for the MU-PC interface addressed by this amendment.
• MU-PC connector interfaces - the physical mating interfaces for MU connectors with physically contacting end faces.
• physically contacting fibres - fibre ends intended to meet directly at the connection point.
• enhanced macro bend multimode fibres - multimode fibres designed for better bend tolerance.
• 50 µm core diameter fibres - multimode fibres with a 50 µm core size named in the companion reference.

Who uses SIST EN 61754-6-100:2016/oprA1:2026?

This standard is used by fibre optic connector designers, component manufacturers, test laboratories, quality managers, and procurement teams. They use it to specify MU-PC interfaces, update technical drawings and footnotes, check optical-interface references, and make sure supplied parts are described against the same MU connector-family terminology.

What changed in SIST EN 61754-6-100:2016/oprA1:2026 from the previous edition?

SIST EN 61754-6-100:2016/oprA1:2026 amends IEC 61754-6-100:2015. The changes listed in the amendment are updated normative references in Clause 2, wording changes in Clause 3, revised cross-references and table footnotes in Clause 4, a revised CK table entry, updated references around Figure 3 and Table 6, and deletion of IEC 61755-6-1 from the bibliography.

Which standards are used with SIST EN 61754-6-100:2016/oprA1:2026?

Standard	What it contributes
IEC 61754-6	Base MU connector family part used for the connector interface framework.
IEC 61755-3 (all parts)	Connector optical interface parameters for dispersion unshifted single-mode physically contacting fibres.
IEC 63267-3 (all parts)	Connector optical interface parameters for enhanced macro bend multimode fibres with physically contacting 50 µm core diameter fibres.
IEC 61754-4	Related connector interface part cited in Table 2 footnotes.

What does the SIST EN 61754-6-100:2016/oprA1:2026 document contain?

The document contains the amended reference text in Clause 2, the edited description wording in Clause 3, and the interface-related edits in Clause 4. Table 1, Table 2, Table 4, and Table 6 carry the main technical updates, and Figure 3 is tied to the revised reference set. The bibliography is also adjusted to match the current standards list used for MU-PC interface specification and review.

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
