The optical performance criteria are generally well specified for a number
23、 of internationally agreed application areas, for example consulting ITU Recommendations originating in Study Group 15, Optical and other transport networks. Manufacturers using the standards are responsible for meeting the required performance and/or reliability and quality assurance under a recogn
24、ized scheme.

25、 assure interchangeability in physical interfaces between fibre optic active components and devices supplied by different manufacturers, but does not guarantee operation between such devices. This interface standard defines physical interfaces only and no guarantee of performance is implied, nor sho
26、uld it be assumed. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 601

31、xturing is possible for products from different manufacturers 3.5 mechanical fixture features for mounting and fixing the active components and devices on to the counterpart board 3.6 physical interface mechanical interface of case outline, optical interface, electrical interface, etc. NOTE This als
32、o includes assignments of electrical terminals and optical ports. 3.7 seating plane reference plane contacting with the case body or electrical terminals for mounting of the active components and devices 4 Classification Fibre optic transceiver modules can be classified into different forms accordin
33、g to the combination of mating types of electrical and optical interfaces. ? Type 1: fibre optic connector interface with direct solderable type electrical terminals. ? Type 2: fibre optic connector interface with plug-in type electrical terminals. ? Type 3: fibre optic pigtail interface with direct
34、 solderable type electrical terminals. ? Type 4: fibre optic pigtail interface with plug-in type electrical terminals. ? Type 5: module that is not classified into types 1 to 4. NOTE A typical example is a module that has both electrical connectors and non-connector type terminals as an electrical i
35、nterface, such as a coaxial connector for signal and lead terminals for the power supply. 5 Specifications of optical interfaces 5.1 General The optical interface should be selected from those whose interchangeability is guaranteed by other IEC standards (for example, IEC 61754). 5.2 Optical connect
36、or interfaces (types 1, 2 and 5) Detailed drawings of the optical connector interface are not necessarily required when referenced to the appropriate IEC standard. Where an optical connector is not standardized under the IEC system, full detail drawings of the interface shall be presented. 5.3 Pigta
37、il interfaces (types 3, 4 and 5) As a general rule, optical fibres and cables specified in IEC 60794 shall be used for the pigtail interface.

38、port assignments Where an optical port assignment is necessary to differentiate the receiving and transmitting elements for the transceiver they should be identified and tabulated. 6 Specifications of electrical interfaces 6.1 General The electrical interface should be selected from those whose inte
39、rchangeability is guaranteed by other IEC standards (for example, IEC 60130, IEC 60191, IEC 60603, IEC 60807, IEC 61076, etc.) 6.2 Electrical connector interfaces (types 2 and 4) As a general rule, electrical connectors used for the electrical interface of the fibre optic transceiver module should b
40、e those standardized in IEC 60130, IEC 60191, IEC 60603, IEC 60807 and IEC 61076. Detailed drawings of the electrical connector interface are not necessarily required when referenced to the appropriate IEC standard. However, the mechanical datum necessary to guarantee interchangeability shall be spe
41、cified in the drawings. Where an electrical connector is not standardized under the IEC system, full detail drawings of the interface shall be presented. 6.3 Non-connector type interfaces (types 1 and 3) As a general rule, non-connector type interfaces used as the electrical interface for the fibre
42、optic transceiver module should be those specified in IEC 60191. In this case, detailed drawings of the electrical interface are not necessarily required when referenced to the appropriate IEC standard. However, the mechanical datum necessary to guarantee interchangeability shall be specified in the
43、 drawings. Where an electrical interface is not standardized under the IEC system, the electrical interface shall be specified as complying with the requirements of IEC 60191-1. Numbering of electrical terminals Electrical terminals of the non-connector type interface should be identified by numbers
44、 according to the system specified in IEC 60191. Electrical terminals of the connector type shall be numbered using the system appropriate to the connector and associated IEC reference. In general, this will involve the use of letters for rows and numbers for pins along the rows. 6.4 Electrical term
45、inal assignment Each electrical pin shall have its functionality (e.g. power, ground, data, etc.) assigned and tabulated in a supplementary table according to the electrical terminal number. 7 Outline and footprint of active components and devices 7.1 Drawings of case outline The case outline of the
46、 active components and devices in subsequent parts of IEC 62148 shall be presented and interpreted as complying with the requirements described in ISO 1101.

These dimensions and tolerances must be consistent with those of the footprint. BSI 22 July 2002 Page 7 EN 621481:2002 Licens
