Overview

EN 61754-26:2012 (IEC 61754-26:2012) specifies the standard interface dimensions for the type SF optical board connector family. It defines dimensional and geometric requirements for a multiway plug/socket connector set that uses normal glass fibre and the physical-contact technique to join flexible optical boards and ribbon fibres. The standard covers plug endface geometry, socket micro-hole arrays, fibre positions and adaptor interfaces for 2 to 16 fibres.

Key Topics

• Scope and intermateability
  • Defines the SF connector family interfaces and specifies that IEC 61754-26‑1 (plug) mates with IEC 61754-26‑2 (socket).
• Mechanical geometry and tolerances
  • Detailed flat-interface dimensions for plug, socket and adaptor (illustrated with figures and tables).
  • Symmetry requirement of cable/fibre layouts relative to the X axis: within 0.02 mm.
• Plug endface and fibre preparation
  • Endface geometry and chamfer angle (25°–65°) and coating removal length (0.75–0.9 mm) are specified for reliable physical contact.
  • Minimum fibre/core clearance and positional tolerances for 2–16 fibre variants are provided.
• Socket micro-hole array
  • Multiway micro holes align and capture plug fibres; triangular or circular cross-sections allowed.
  • Micro-hole inner diameter tolerance example: ML ≈ 0.1255–0.1265 mm (inscribed circle for triangular holes).
  • Guide area constraints: the guide area of a fibre shall be more than 0.045 mm from the centre of a micro hole.
• Documentation and figures
  • The standard contains figures (plug/socket examples, endface detail, micro-hole geometry, positions of fibres) and many dimension tables for manufacturers and designers.

Applications

EN 61754-26 is intended for use where compact, multiway optical board connections are required:

• Flexible optical boards and ribbon-fibre interconnects in telecom and datacom equipment
• Optical backplanes and high-density board-to-board optical links
• Module and transceiver interface design where physical-contact, ferrule-less mating is preferred
• Manufacturing and quality control processes that require strict mechanical tolerances for mating performance

Who uses this standard

• Connector and optical-board manufacturers (design, tooling and production)
• PCB and optical backplane designers integrating SF-family connectors
• Test laboratories, QA and acceptance teams verifying mechanical compatibility
• Procurement and standards teams specifying intermateable optical interfaces

Related Standards

• IEC 61754 series (fibre optic connector interfaces)
• IEC 60793 (fibre types referenced: A1a multimode and B single‑mode as applicable)
• Patent/licensing note: a patent claim related to IEC 61754‑26 is declared (holder: Nippon Telegraph and Telephone Corporation).

Keywords: interface dimensions for type SF optical board connector, EN 61754-26, SF connector family, fibre optic connector interfaces, micro holes array, plug endface geometry.

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 made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC
