22、ON _ FIBRE OPTIC ACTIVE COMPONENTS AND DEVICES PACKAGE AND INTERFACE STANDARDS Part 2: SFF 10-pin transceivers FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees)
23、. 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 Sp
24、ecifications (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 organizat
25、ions 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 matte
26、rs 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
27、 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
28、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
29、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
30、 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 wh
31、atsoever, 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 publ
32、ications 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 St
33、andard IEC 62148-2 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre optics. This standard should be read in conjunction with IEC 62148-1. This second edition cancels and replaces the first edition published in 2003. It constitutes a
34、technical revision. With respect to the previous edition, this edition includes 10-pin SFF-LC, and SFF MU devices. It also cancels and replaces the first edition of IEC 62148-7 and the first edition of IEC 62148-9. 4 62148-2 IEC:2010 The text of this standard is based on the following documents: FDI
35、S Report on voting 86C/975/FDIS 86C/981/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. A list of all parts of the IEC 62148 se
36、ries can be found, under the general title Fibre optic active components and devices Package and interface standards, on the IEC website. The 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
37、.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 62148-2 IEC:2010 5 INTRODUCTION Fibre optic transceivers are used to convert electrical signals into optical signals and vice versa. This
38、 standard covers the physical interface for a 10-pin small form factor (SFF) transceiver. This transceiver is designed for use with the SFF MU/MT-RJ/LC duplex optical connector and with through-hole printed circuit-board applications. 6 62148-2 IEC:2010 FIBRE OPTIC ACTIVE COMPONENTS AND DEVICES PACK
39、AGE AND INTERFACE STANDARDS Part 2: SFF 10-pin transceivers 1 Scope This part of IEC 62148 covers the physical interface specifications for the SFF MT-RJ/LC/MU duplex 10-pin fibre optic transceiver module family. The intent of this standard is to adequately specify the physical requirements of an op
40、tical transceiver that will enable mechanical interchangeability of transceivers complying with this standard both at the printed circuit wiring board and for any panel-mounting requirement. 2 Normative references The following referenced documents are indispensable for the application of this docum
41、ent. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
