Full title and description

Fibre optic interconnecting devices and passive components - Fibre optic connector interfaces - Part 26: Type SF connector family. Defines the standard interface dimensions for the Type SF optical board connector, which uses conventional glass fibre and a physical-contact technique to connect flexible optical boards and ribbon fibres.

Abstract

This part of IEC 61754 specifies the mechanical interface dimensions and related interface requirements for the Type SF connector family (optical board connectors). It provides dimensional drawings, key tolerances and mating-interface references intended to ensure interchangeability between mating components used to connect flexible optical printed circuits and ribbon fibre assemblies.

Scope

Specifies the interface dimensions for the Type SF optical board connector family, covering the form, fit and mating relationships required to connect flexible optical boards and ribbon fibres using a physical-contact connection. The scope is limited to defining mechanical interfaces (dimensional drawings and tolerances) rather than detailed performance or test methods.

Key topics and requirements

• Defined mechanical interface dimensions and tolerances for Type SF connectors (outline and mating interfaces).
• Alignment and locating features to ensure repeatable mating of optical boards and ribbon-fibre assemblies.
• Specifications for fibre position referencing and ferrule/guide features necessary for physical-contact connections.
• Reference drawings and nominal dimensions for manufacturers and equipment designers to ensure interchangeability.
• Notes on intended application (optical board to ribbon-fibre connections) and limits of the interface specification (mechanical interface, not detailed optical performance tests).

Typical use and users

Used by connector and module manufacturers, optical transceiver and subsystem designers, printed-circuit-optical-board (POB/Flexible optical board) engineers, and specification writers who require defined mechanical interfaces for board-mounted optical connectors. Also referenced by procurement and quality teams to verify mechanical interchangeability. National standards bodies and companies adopting the IEC text into regional standards (EN, DIN, etc.) use it for harmonised product specifications.

FAQ

Q: What is this standard?

A: IEC 61754-26:2012 is the international standard that defines the mechanical interface dimensions and related interface information for the Type SF family of fibre-optic optical board connectors (for flexible optical boards and ribbon fibres).

Q: What does it cover?

A: It covers the form, fit and mating-interface dimensions and tolerances for Type SF connectors — essentially the drawings and dimensional requirements needed to ensure mechanical interchangeability between mating parts. It does not itself provide detailed optical performance tests (those are covered in separate IEC/EN test standards).

Q: Who typically uses it?

A: Connector manufacturers, optical module and subsystem designers, PCB/optical-board engineers, procurement/specification authors and test labs that need a defined mechanical interface for board-mounted optical connectors. Regional standards committees also adopt the IEC text into national or regional standards.

Q: Is it current or superseded?

A: As published, IEC 61754-26:2012 is the first edition (2012). The IEC webstore lists the publication as 2012 with a stability indication; users should check national catalogues or the IEC webstore for any amendments or revisions after 2012 to confirm current status before use.

Q: Is it part of a series?

A: Yes — it is Part 26 of the IEC 61754 series, which contains multiple parts that standardise connector-family interface dimensions for many connector types (SC, LC, MPO, MT, etc.). Use the series index to locate related connector-family interface documents.

Q: What are the key keywords?

A: Type SF, optical board connector, interface dimensions, physical contact, ribbon fibre, flexible optical board, IEC 61754.
