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) 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 61300-3-35 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.

Fibre optic connector endface visual and automated inspection
1 Scope
This part of IEC 61300 describes methods for quantitatively assessing the endface quality of a
polished fibre optic connector. The information is intended for use with other standards which
set requirements for allowable surface defects such as scratches, pits and debris which may
affect optical performance. In general, the methods described in this standard apply to 125 μm
cladding fibres contained within a ferrule and intended for use with sources of ≤2 W of input
power. However, portions are applicable to non-ferruled connectors and other fibre types.
Those portions are identified where appropriate.
2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies.
None.
3 Measurement
3.1 General
The objective of this standard is to prescribe methods for quantitatively inspecting fibre optic
endfaces to determine if they are suitable for use. Three methods are described: A: direct view
optical microscopy, B: video microscopy, C: automated analysis microscopy. Within each
method, there are hardware requirements and procedures for both low resolution and high
resolution systems. High resolution systems are to be utilized for critical examination of the
glass fibre after polishing and upon incoming quality assurance. High resolution systems are
typically not used during field polishing or in conjunction with multimode connectors. Low
resolution systems are to be utilized prior to mating connectors for any purpose. All methods
require a means for measuring and quantifying defects.
There are many types of defects. Commonly used terminology would include: particles, pits,
chips, scratches, embedded debris, loose debris, cracks, etc. For practical purposes, all
defects will be categorized in one of two groups. They are defined as follows:
scratches: permanent linear surface features;
defects: all non-linear features detectable on the fibre. This includes particulates, other debris,
pits, chips, edge chipping, etc.
All defects and scratches are surface anomalies. Sub-surface cracks and fractures are not
reliably detectable with a light microscope in all situations and are therefore not covered within
this standard. Cracks and fractures to the fibre may be detected with a light microscope and
are generally considered a catastrophic failure.
---------------------- Page: 9 ----------------------
SIST EN 61300-3-35:2010
– 6 – 61300-3-35 © IEC:2009(E)
Differentiating between a scratch and all other defects is generally intuitive to a human being.
However, to provide clarity, and for automated systems, scratches are defined as being less
than 4 μm wide, linear in nature, and with a length that is at least 30 times their width. As the
width dimension is not practical to visually measure below 3 μm, these figures can be grossly
estimated.
Defects size is defined for methods A and B as the diameter of the smallest circle that can
encompass the entire defect. Defect size for method C can be either the actual measured
surface area or the diameter of the smallest circle than can encompass the entire defect.
Some fibre types have structural features potentially visible on the fibre endface. Fibres that
use microstructures to contain the light signal, such as photonic band-gap and hole-assisted
fibres, can have an engineered or random pattern of structures surrounding the core. These
features are not defects.
For methods A and B below, it is recommended that visual gauge tools be developed to
facilitate the measurement procedure. For method A, an eyepiece reticule is recommended.
For method B, an overlay is recommended.
3.2 Measurement conditions
No restrictions are placed on the range of atmospheric conditions under which the test can be
conducted. It may be performed in controlled or uncontrolled environments
3.3 Pre-conditioning
No minimum pre-conditioning time is required.
3.4 Recovery
Since measurements are to be made at standard test conditions, no minimum recovery time is
required.
4 Apparatus
4.1 Method A: direct view optical microscopy
This method utilizes a light microscope in which a primary objective lens forms a first image
that is then magnified by an eyepiece that projects the image directly to the user’s eye. It shall
have the following features and capabilities:
• a suitable ferrule or connector adapter;
• a lig
