24、ve 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 should it be assumed. 2 Normative references The following referenced documen

32、rminals. 0 Type 2: fibre optic connector interface with plug-in type electrical terminals 0 Type 3: fibre optic pigtail interface with direct solderable type electrical terminals. 0 Type 4: fibre optic pigtail interface with plug-in type electrical terminals. 0 Type 5: module that is not classified
33、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 interface, such as a coaxial connector for signal and lead terminals for the power supply. 5 Specifications of optical interfaces 5.1 General The optical interf
34、ace should be selected from those whose interchangeability is guaranteed by other IEC standards (for example, IEC 61754). 5.2 Optical connector interfaces (types 1, 2 and 5) Detailed drawings of the optical connector interface are not necessarily required when referenced to the appropriate IEC stand
35、ard. Where an optical connector is not standardized under the IEC system, full detail drawings of the interface shall be presented. 5.3 Pigtail 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.

37、d be selected from those whose interchangeability 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 fibr
38、e optic transceiver module should be 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 guaran
39、tee interchangeability shall be specified 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
40、electrical interface for the fibre 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 interchan
41、geability shall be specified in the 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 interf
42、ace should be identified by numbers 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
43、along the rows. 6.4 Electrical terminal 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 c

46、ons and dimensions should be specified in the drawings. Their values and tolerances should be tabulated. These dimensions and tolerances must be consistent with those of the footprint.
