23、OMMUNICATION FREQUENCY RESPONSE OF OPTICAL-TO-ELECTRIC CONVERSION DEVICE IN HIGH-FREQUENCY RADIO OVER FIBRE SYSTEMS MEASUREMENT METHOD FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (

24、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 Report

25、s, 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

26、-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

27、 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 a

28、ccepted 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 interna

29、tional 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

30、 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

31、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

32、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

33、 of the referenced publications is indispensable for the correct application of this publication. International Standard IEC 62803 has been prepared by IEC technical committee 103: Transmitting equipment for radiocommunication. The text of this standard is based on the following documents: FDIS Repo

34、rt on voting 103/147/FDIS 103/148/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. BS EN 62803:2016IEC 62803:2016 IEC 2016 5 The

35、 committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised

36、 edition, or amended. BS EN 62803:2016 6 IEC 62803:2016 IEC 2016 INTRODUCTION A variety of microwave-photonic devices are used in wireless communication and broadcasting systems. A photo-receiver is an interface which converts an optical signal to an electronic signal. This International Standard ha

37、s been prepared to provide methods for evaluating and calibrating high speed photo-receivers to be used in Radio over Fibre systems. The method utilizes a Mach-Zehnder modulator for generating two-tone lightwaves as stimulus signals, to provide simpler and easier methods than the conventional method

38、 utilizing a complex two-laser system phase-locked with each other. The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning a calibration method and device for light intensity mea

44、sponse of optical-to-electric conversion devices in wireless communication and broadcasting systems. The frequency range covered by this standard goes up to 100 GHz (practically limited up to 110 GHz by precise RF power measurement) and the wavelength band concerned is 0,8 m to 2,0 m. 2 Normative re

45、ferences The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies

46、. There are no normative references in this document. 3 Terms, definitions and abbreviations 3.1 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1.1 conversion efficiency ratio of the output current to the input optical power defined by inoutPIk

47、= (1) Note 1 to entry: See Figure 1. BS EN 62803:2016 8 IEC 62803:2016 IEC 2016 Figure 1 Definition of “conversion efficiency “ Note 2 to entry: Conversion efficiency k, which depends on modulating signal frequency,is often expressed in dB as the ratio to the reference conversion efficiency of 1 (am

48、pere per watt). It is well known, however, that dB has two definitions. One is the optical conversion efficiency kodBo calculated from 10log10(Iout/Pin), and the other is the electrical conversion efficiency kedBe calculated from 20 log10(Iout/Pin). As for the conversion efficiency k, the numerator

49、is the amplitude of the electrical output signal, and the denominator is the power of optical input signal. Therefore, both definitions of dB for conversion efficiency koand keare shown as follows: inout10olog10dBPIkkoo= (2) inout10elog20dBPIkkee= (3) 3.1.2 two-tone lightwave lightwave that contains two dominant spectral components whose power difference is relatively small and frequency separation is stable Note 1 to entry: Undesir
