Overview
IEC 61754-13:2024 - "Fibre optic interconnecting devices and passive components - Fibre optic connector interfaces - Part 13: Type FC‑PC connector family" - is the third edition (replacing the 2006 edition) that specifies standard interface dimensions and mechanical requirements for the FC‑PC connector family. The document defines plug, adaptor and active‑device receptacle interfaces (plug: IEC 61754‑13‑1; adaptor: IEC 61754‑13‑2; active device receptacle: IEC 61754‑13‑3), and includes drawings, tables and pin‑gauge requirements to ensure consistent mechanical and optical mating. This edition is a technical revision that updates normative references, adds intermateability rules, revises plug dimensions and introduces additional ferrule/grade classifications. Corrigendum 1 (2025‑06) is included.
Key topics
- Interface scope and drawings: Standardized figures and tables for the FC‑PC plug connector, adaptor connector, and active device receptacle interfaces - including mechanical datums and reference planes.
- Dimensions and tolerances: Specified diameters, thread details (e.g., M8 × 0.75 coupling thread), ferrule nominal diameter (2.5 mm family) and dimensional limits required for interchangeability.
- Ferrule grades and characteristics: Defined ferrule grade classes and associated dimensional bands for consistent optical contact and alignment. (New grades added in this edition.)
- Intermateability: New clause defining which plug, adaptor and receptacle interfaces are compatible and how mating configurations should behave to guarantee mechanical fit and optical contact.
- Alignment and coupling features: Requirements for alignment sleeves (rigid bore or resilient sleeve), pin gauges and eccentricity limits (e.g., dome eccentricity tolerances) that affect insertion loss and return loss performance.
- Normative references: Updated links to foundational documents such as IEC 61754‑1 (general guidance) and IEC 61755‑3‑1 (optical interface for 2.5 mm zirconia PC ferrules).
Applications
Who uses IEC 61754‑13:2024 and why:
- Connector manufacturers - to design FC‑PC plugs, adapters and receptacles that meet international mechanical interface requirements.
- Telecommunications and datacom equipment designers - to ensure mechanical compatibility and reliable mating in optical modules, transceivers and patch panels.
- Test & qualification labs - to verify dimensional compliance using pin gauges, alignment sleeves and specified tolerances.
- Procurement and certification teams - to specify compliant components and ensure interoperability across suppliers.
- OEMs and system integrators - to confirm that field assemblies, adapters and active devices will mate properly without mechanical or optical degradation.
Benefits include predictable intermateability, reduced field failures, consistent optical alignment and simplified supply‑chain interoperability for FC‑PC fibre optic connector interfaces.

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 is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which

screw coupling mechanism 7
coupling mechanism in which a plug connector is inserted into an adaptor connector or an active
device receptacle, and a female screw formed on a coupling nut of the plug connector is
tightened with a male screw formed on the adaptor connector or the active device receptacle
4 Description
The parent connector for type FC connector family is a single position plug connector set of
plug/ and adaptor configuration which is characterized by a 2,5 mm nominal ferrule diameter. It
includes a thread screw coupling mechanism, which is spring loaded relative to the ferrule in
the direction of the optical axis. The coupling can be released by loosening the screw, and the
plug connector can be detached from the optical adapter, the adaptor connector, or the active
device receptacle. The plug has a single male key which may be used to orient and limit the
relative position between the connector and the component to which it is mated. The optical
alignment mechanism of the connectors is of a rigid bore sleeve or a resilient sleeve style.
