Overview
EN IEC 61754-4:2022/A1:2026 is an amendment to the established standard for fibre optic interconnecting devices and passive components, specifically focusing on the fibre optic connector interfaces for the Type SC (Subscriber Connector) connector family. Published by CLC and harmonized with IEC, this amendment updates requirements and references for the SC connector family, ensuring global alignment and improved consistency for optical fibre connectivity.
This standard revision serves manufacturers, system integrators, and quality assurance professionals working with fibre optic connectors in telecom, data centers, and industrial networks, helping ensure that products and installations meet the latest technical and performance requirements.
Key Topics
- SC Connector Interface Definitions: Updates to drawings and tables for simplex and duplex SC connector interfaces, providing clearer dimensional references.
- Reference Alignment: Replacement of earlier reference data with updated cross-references to the IEC 61755-3 and IEC 63267-3 standards, ensuring harmonized requirements for connector optical interfaces and measurement techniques.
- Grade Characteristics Update: Amendments specifying that certain connector grades must adhere to requirements found in related IEC standards, contributing to uniform product evaluation.
- Outdated Information Removal: Elimination of superseded notes, obsolete figures, and bibliography entries to maintain clarity and reduce the risk of referencing out-of-date information.
- Technical Corrections: Minor dimensional updates, such as adjustments to plug connector and device receptacle measurements and revised specifications for surface roughness, to reflect current manufacturing capabilities and field realities.
Applications
The EN IEC 61754-4:2022/A1:2026 standard is critical in the design, manufacturing, and deployment of fibre optic network components, especially where SC connectors are used. Its applications span:
- Telecommunications Infrastructure: SC connectors are widely adopted in optical networks for their reliability and easy field installation, making compliance with this standard essential for telecom equipment manufacturers and operators.
- Data Centers: High-density fibre deployments in data centers require consistent and robust connector interfaces for fast, error-free connections and long-term stability.
- Industrial and Enterprise Networks: SC connectors are found in process control, SCADA, and other mission-critical environments, demanding adherence to standardized tolerances.
- Product Quality Assurance: Testing laboratories reference these standards to verify product conformity and performance, offering assurance in procurement and deployment.
Related Standards
The amendment draws direct links to several important IEC documents, fostering compatibility and consistency across the fibre optic connector ecosystem:
- IEC 61754 series: Defines connector interfaces for various connector families, including SC, ensuring interoperability.
- IEC 61755-3 (all parts): Specifies connector parameters for dispersion-unshifted single-mode physically contacting fibres, now referenced for relevant measures and grades.
- IEC 63267-3 (all parts): Provides requirements for connector interfaces using enhanced macro bend multimode fibres, referenced for updated dimensional and performance specifications.
- SIST EN IEC 61754-4: The 2022 version is the base document for SC connector interfaces in Slovenia and across CENELEC countries.
By aligning connector dimensional, grading, and testing requirements with these international standards, EN IEC 61754-4:2022/A1:2026 supports a harmonized approach to fibre optic interconnection, quality, and compatibility across the global market.

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 m
