SIST EN 61754-4-100:2016/oprA1:2026 is Amendment 1 to the fibre optic connector interface standard for the Type SC connector family, published by CLC/CENELEC. It updates the simplified receptacle SC-PC connector interfaces and the reference documents used to define them. Engineers, manufacturers, test labs, and quality teams use it when they need the SC interface definition to match the current IEC reference set.

What does SIST EN 61754-4-100:2016/oprA1:2026 specify?

SIST EN 61754-4-100:2016/oprA1:2026 specifies changes to the SC connector interface part for simplified receptacle SC-PC interfaces. The amendment is organized as a foreword, Clause 2 on normative references, Clause 3 on description, Clause 4 on interfaces, and a bibliography update.

In practice, this means the document is not a full rewrite of the interface standard. It is a targeted update that keeps the base SC interface content aligned with current IEC references and current wording in the tables and figures.

What are the key requirements of SIST EN 61754-4-100:2016/oprA1:2026?

The main technical effect of SIST EN 61754-4-100:2016/oprA1:2026 is to replace outdated references and tighten the way the interface is pointed back to its governing IEC parts.

• Clause 2 replaces the reference to IEC 61754-4:2013 with IEC 61754-4. In practice, users should apply the current base Type SC family document when checking the interface.
• Clause 2 replaces IEC 61755-3-1 with IEC 61755-3 (all parts) and adds IEC 63267-3 (all parts). This matters because the optical interface references now point to the relevant series for the fibre types covered by the amendment.
• Clause 3 changes item f) so that it cites IEC 61754-4. This keeps the descriptive text aligned with the updated base family standard.
• Clause 4 updates footnotes in Tables 1 and 2 to IEC 61754-4. For users, that means the tables remain linked to the correct family definition.
• Clause 4 revises Table 4, row CK, by replacing the earlier surface-finish designation with an Ra-based roughness requirement. In practice, the interface is now controlled by a roughness parameter, which is easier to state and check in manufacturing and inspection.
• Clause 4 updates the text above Figure 3 to refer to the IEC 61755-3 series and the IEC 63267-3 series. This matters when selecting the right optical interface document for single-mode or multimode use.
• Clause 4 updates Table 6 footnotes so they point to the same current series references. That keeps the supporting notes consistent with the rest of the amendment.
• The bibliography deletes IEC 61755-6-1 and its associated footnote. Users should therefore follow the revised reference set in this amendment rather than the removed citation.

What terms does SIST EN 61754-4-100:2016/oprA1:2026 define?

• Type SC connector family - The connector family covered by this part, used as the basis for the interface definition.
• Simplified receptacle - The receptacle form of the SC interface that this amendment addresses.
• SC-PC - The SC physical-contact connector interface, where the fibre ends are intended to contact physically.
• Physically contacting fibres - Fibres and interfaces designed to make physical contact at the connector interface.
• Dispersion unshifted single-mode - The single-mode fibre category named in the updated reference series for optical interface parameters.
• Enhanced macro bend multimode fibres - The multimode fibre category named in the updated reference series for optical interface parameters.
• Ra - The arithmetic mean surface roughness used here to express the updated finish requirement in Table 4.

Who uses SIST EN 61754-4-100:2016/oprA1:2026?

SIST EN 61754-4-100:2016/oprA1:2026 is used by people who design, make, specify, or verify SC fibre optic connector interfaces.

Typical users include:

• connector and device designers working on SC receptacles and mating interfaces
• manufacturers of fibre optic interconnecting devices and passive components
• test and conformity laboratories checking interface definitions and surface finish
• quality managers and buyers comparing products against the correct SC family references
• standards and compliance teams maintaining product documentation against the IEC series

The amendment is useful when a team needs to confirm that drawings, product specifications, and test references all point to the same current interface documents.

What changed in SIST EN 61754-4-100:2016/oprA1:2026 from the previous edition?

SIST EN 61754-4-100:2016/oprA1:2026 changes the earlier SC interface amendment by updating references and associated wording.

The stated changes are:

• IEC 61754-4:2013 is replaced by IEC 61754-4
• IEC 61755-3-1 is replaced by IEC 61755-3 (all parts)
• IEC 63267-3 (all parts) is added
• wording in Clause 3 is updated
• footnotes in Tables 1, 2, and 6 are updated
• Table 4 row CK is revised to an Ra-based finish requirement
• the text above Figure 3 is updated
• IEC 61755-6-1 is deleted from the bibliography

Which standards are used with SIST EN 61754-4-100:2016/oprA1:2026?

Standard	What it contributes
IEC 61754-4	Base Type SC connector family standard used as the main reference for the interface
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 50 µm core diameter

What does the SIST EN 61754-4-100:2016/oprA1:2026 document contain?

SIST EN 61754-4-100:2016/oprA1:2026 contains clause-by-clause amendment instructions rather than a full standalone interface specification. It updates normative references, descriptive text, interface table footnotes, and one surface-finish entry in Table 4. It also updates the text associated with Figure 3 and the notes in Table 6. The bibliography is edited to remove one no-longer-used reference.

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 internationa
