IEC 61754-26:2012

Overview

IEC 61754-26:2012 is an international standard developed by the International Electrotechnical Commission (IEC) that defines the interface dimensions for the Type SF optical board connector family. This standard applies to fibre optic interconnecting devices and passive components, specifically focusing on fibre optic connector interfaces within the Type SF connector family.

The Type SF connector family utilizes normal glass fibre and a physical contact technique to connect flexible optical boards and ribbon fibres, enabling precise alignment and mating of optical fibres without the use of ferrules or springs. This standard ensures compatibility and interchangeability across devices and manufacturers, promoting global consistency in fibre optic connector design.

Key Topics

• Scope and Description
  IEC 61754-26:2012 specifies the standard interface dimensions for the Type SF optical board connectors. These are multiway connectors featuring a plug/socket configuration where multiway cantilevered optical fibres inside the plug mate with the socket fibres via physical contact.

• Connector Design

  • Plug Connector: Contains buckled optical fibres designed to mate physically with socket fibre ends.
  • Socket Connector: Features an array of micro holes that position, capture, and align the plug fibres during engagement.
  • The physical contact connection is achieved by the plugging force of fibres themselves without requiring additional ferrules or springs.

• Interface Specifications
  The document details two core interface types:

  • IEC 61754-26-1: SF Plug connector flat interface, supporting 2 to 16 fibres
  • IEC 61754-26-2: SF Socket connector flat interface, supporting 2 to 16 fibres
    Both interfaces are designed for intermateability, ensuring seamless connection.

• Dimensional Data and Geometry
  The standard provides precise measurements for key features such as plug and socket connector dimensions, fibre positions, micro hole arrays, and adaptor interface sizes, ensuring exact alignment and consistent performance.

• Compliance and Patent Information
  The standard indicates potential patent rights related to this connector family, with licensing details available, promoting fair use and adoption across industries.

Applications

The IEC 61754-26:2012 standard is critical for manufacturers, designers, and engineers involved in the production and deployment of fibre optic communication systems involving flexible optical boards and ribbon fibres. Relevant applications include:

• Telecommunications Infrastructure:
  Enables high-density optical connections with reliable physical contact, improving signal integrity and reducing losses.

• Data Centers and Networking:
