Fibre optic active components and devices - Performance standards - Part 12: Distributed feedback laser diode device for analogue radio over fibre systems

IEC 62149-12:2023 This part of IEC 62149 defines performance specifications for distributed feedback laser diode (DFB-LD) devices used in analogue radio over fibre (RoF) systems. It defines product performance requirements together with a series of tests and measurements with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run on a “once-off” basis to prove a product’s ability to satisfy the performance requirements.

IEC 62149-12:2023 définit les spécifications de performances des dispositifs à diode laser à rétroaction répartie (DFB-LD) utilisés dans les systèmes de type radio analogique sur fibre (RoF). Elle définit les exigences de performances du produit, accompagnées d’une série d’essais et de mesures comportant des conditions, des sévérités et des critères d’acceptation/de rejet clairement définis. Les essais sont destinés à être effectués en une seule et unique fois, afin de démontrer la capacité d'un produit donné à satisfaire aux exigences de performances.

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 62149-12 has been prepared by subcommittee 86C: Fibre optic systems and active devices,

of IEC technical committee 86: Fibre optics. It is an International Standard.
The text of this International Standard is based on the following documents:

105 INTRODUCTION

106 Distributed feedback laser diode (DFB-LD) devices for analogue radio over fibre (A-RoF)

107 systems are used to convert electrical radio signals into optical signals. This part of IEC

108 62149 covers the performance specification for DFB-LD devices in A-RoF systems. The

109 optical and electrical performance criteria are generally well specified for a number of

110 internationally agreed upon application areas, such as ITU-T Recommendation G.9803 and

111 IEC 62149-10. This standard provides optical and electrical performance specifications for

112 RoF transceivers. These transceivers are necessary for operation of A-RoF systems, because

113 the RoF transmitter requires a light source such as a DFB-LD device. DFB-LD devices for RoF

114 transceivers are supplied by different manufacturers. However, they do not guarantee the

115 operation of DFB-LD devices in A-RoF systems. Manufacturers using the standards are

116 responsible for meeting the required performance and/or reliability and quality assurance

117 under a recognized scheme.

126 This part of IEC 62149 defines performance specifications for distributed feedback laser diode

127 (DFB-LD) devices used in analogue radio over fibre (RoF) systems. It defines product

128 performance requirements together with a series of tests and measurements with clearly

129 defined conditions, severities, and pass/fail criteria. The tests are intended to be run on a

130 “once-off” basis to prove a product’s ability to satisfy the performance requirements.
