Overview

EN IEC 61754-4:2022/prA1:2025 - Amendment 1 updates the Type SC connector family interfaces in the IEC/EN 61754‑4 series. This Committee Draft for Vote (CDV) proposes edits to interface drawings, dimensional tables and grade characteristics for simplex and duplex SC PC and angled‑PC plug connectors, and adds important normative references. The draft is under IEC SC 86B and submitted for parallel voting (circulation 2025‑10‑17 to 2026‑01‑09); it is still under study and should not be used as a final reference.

Key topics and technical changes

• Normative references added
  • IEC 61755‑3 series (connector optical interface parameters for dispersion‑unshifted single‑mode physically contacting fibres)
  • IEC 63267‑3 series (connector parameters for enhanced macro bend multimode fibres, 50 µm core physically contacting)
• Interface drawings and dimensions
  • Replacement of simplex and duplex PC plug connector interface figures with updated drawings.
  • Specific dimensional edits: e.g., Table 17 row P changed from 9.2 mm to 9.1 mm; Table 13 row DB now includes 12.65 mm and 12.75 mm values.
  • Deletions of some angled PC plug connector figures and certain legacy notes.
• Grade characteristics
  • Grade A: “Grade not specified at this time”
  • Grades B–D: redirected to IEC 61755‑3 series
  • Certain multimode grade values: redirected to IEC 63267‑3 series
• Test/inspection details
  • Pin gauge row CK updated to a different surface finish requirement (listed in draft as Ra: ≤0,000 2).
  • Removal of legacy endface dome offset/eccentricity notes (previous 50 µm references deleted).
• Bibliography cleanup
  • Removal of outdated IEC 61755‑3‑1, 61755‑3‑2 and IEC 61755‑6‑1 references.

Applications and users

This amendment is essential for:

• Connector manufacturers ensuring mechanical interchangeability and updated dimensional tolerances for SC connector designs.
• Component designers integrating SC receptacles in active devices and patch panels.
• Quality and test laboratories that verify connector endface geometry and grade characteristics in line with referenced IEC interface and endface standards.
• Procurement and compliance teams referencing up‑to‑date standards for product acceptance and interoperability in telecom, datacom and FTTx installations.

Related standards

• IEC 61754‑4 (Part 4: Type SC connector family) - base document
• IEC 61755‑3 series - connector optical interfaces / endface parameters (single‑mode)
• IEC 63267‑3 series - connector parameters for enhanced macro bend multimode fibres

Note: This amendment has a proposed stability date of 2032 and remains a draft; consult the final published EN/IEC document and national adoption for authoritative requirements.
