Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-35: Examinations and measurements - Fibre optic cylindrical connector endface visual inspection

Quantitatively assess the endface quality of a polished fiber 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 document apply to fibers contained within a ferrule, however portions are applicable to non-ferruled connectors. Those portions are identified where appropriate.

FOREWORD
A PAS is a technical specification not fulfilling the requirements for a standard, but made available to the
public.
IEC-PAS 61300-3-35 has been processed by subcommittee 86B: Fibre optic interconnecting devices and
passive components, of IEC technical committee 86: Fibre optics.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document:
Draft PAS Report on voting
86B/1677/PAS 86B/1701/RVD
Following publication of this PAS, the technical committee or subcommittee concerned will investigate the
possibility of transforming the PAS into an International Standard.
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all
national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form of
standards, technical specifications, technical reports or guides and they are accepted by the National Committees
in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any divergence
between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the

latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

1 Scope
The purpose of this part of IEC 61300 is to quantitatively assess the endface quality of a
polished fiber 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 document apply to fibers
contained within a ferrule, however portions are applicable to non-ferruled connectors. Those
portions are identified where appropriate.
2 Normative references
The following normative document contains provisions which, through reference in this text,
constitutes provisions of this part of IEC 61300.
IEC 61300-1 Ed. 1.0b: 1995, Fibre optic interconnecting devices and passive components -
Basic test and measurement procedures - Part 1: General and guidance 86B
3 General description
Two methods are described: (A) Optical microscope and (B) CCD array camera with monitor.
In method A, the required equipment is an optical microscope capable of direct illumination with
a calibrated eyepiece reticle to measure the size of features in the image. In method B, an
optical microscope is used in conjunction with a CCD array camera to project an image onto a
video monitor at a known magnification. In both methods A and B, features are identified and
measured by an operator.
3.1  Morphological Definitions of Defect Features
For purposes of this document the following defects shall apply for all measurement methods.

Scratches: permanent linear surface features derived from polishing or handling
Pits: permanent non-linear features caused by surface damage during polishing or handling.
Cracks: permanent fracture lines that may extend to the surface of the fiber
Surface debris: non-permanent features that can be removed by cleaning.
3.2 Measurement conditions
No restrictions are placed on the range of atmospheric conditions under which the test can be
conducted. It may 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
The apparatus consists of the following elements.

4.1 Method A: Optical
The apparatus for method A (figure 1) consists of an optical microscope with the following
features and capabilties:
– A suitable ferrule or connector plug holder and a positioning stage

– Minimum total magnification of 200X, where total magnification is defined as the product of
the objective lens and eyepiece lens magnifications.

– Resolving power of 1,0 µm
The resolving power is determined by the numerical aperature of the objective lens and
wavelength of the illuminating light as giv
