Overview

EN 62496-3-1:2010 (identical to IEC 62496-3-1:2009) is a European performance standard for flexible optical circuit boards (FOCBs) that use unconnectorized optical glass fibres in a controlled environment. The standard defines performance requirements, quality classification and test methods for fibre flexible OCBs (FFOCBs), clarifying how optical fibres are routed, fixed and protected on a flexible substrate and how the assemblies should be evaluated for reliability.

Key topics

• Scope and definitions
  • Applies to FFOCBs where unconnectorized glass optical fibres are fixed to a flexible polymer substrate and covered by a protection layer.
  • Introduces terms such as FFOCB, OCB body, OCB tail and crossing point.
• Performance requirements and classification
  • Outlines required performance characteristics and how to classify quality of flexible OCB assemblies for controlled environments.
• Test methods and environmental checks
  • References standard test procedures for high temperature endurance (dry heat), damp heat, change of temperature, visual inspection, attenuation and return loss.
  • Includes mechanical tests specific to FFOCBs: bending endurance and static pressure endurance (see normative Annexes A and D).
• Test sample planning
  • Requirements for sample size, sequencing and grouping of tests (normative Annex C).
• Fibre types and routing
  • Lists acceptable multimode and single-mode glass fibre categories for FFOCBs and guidance on routing patterns and dimensional specimen details (normative Annex B).
• Documentation
  • Specifies required content for test reports and reference components.

Applications

EN 62496-3-1:2010 is practical for:

• Design and manufacturing teams producing flexible optical circuit boards and fibre-integrated PCBs.
• Test laboratories validating mechanical and optical performance of FFOCBs (bending endurance, static pressure, environmental stress).
• Procurement and quality assurance personnel who need objective quality classification criteria for unconnectorized fibre-installed boards.
• System integrators and electronics suppliers integrating flexible optical wiring into consumer, industrial and controlled-environment electronic equipment.

Keywords: EN 62496-3-1:2010, IEC 62496-3-1, flexible optical circuit boards, FFOCB, unconnectorized optical glass fibres, bending endurance, static pressure endurance, fibre optics testing.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62496-3-1 has been prepared by IEC technical committee 86:
