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.

IEC 62148-22 has been prepared by subcommittee 86C: Fibre optic systems and active devices,

of IEC technical committee 86: Fibre optics. It is an International Standard.

78 FOREWORD

79 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

80 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

81 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

82 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

83 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

84 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

85 in the subject dealt with may participate in this preparatory work. International, governmental and non-

86 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

87 with the International Organization for Standardization (ISO) in accordance with conditions determined by

88 agreement between the two organizations.

89 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

90 consensus of opinion on the relevant subjects since each technical committee has representation from all

91 interested IEC National Committees.

92 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

93 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

94 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

95 misinterpretation by any end user.

96 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

97 transparently to the maximum extent possible in their national and regional publications. Any divergence

98 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

99 the latter.

100 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

101 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

102 services carried out by independent certification bodies.

103 6) All users should ensure that they have the latest edition of this publication.

104 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

105 members of its technical committees and IEC National Committees for any personal injury, property damage or

106 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

107 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

108 Publications.

109 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

110 indispensable for the correct application of this publication.

111 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

112 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
