IEC 62148-1 pdf download.Fibre optic active components and devices – Package and interface standards
This part of IEC 62148 aims to 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 should it be assumed.

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 60191-1, Mechanical standardization of semiconductor devices – Part 1: Preparation of drawings of semiconductor devices IEC 60794 (all parts), Optical fibre cables IEC 61754 (all parts), Fibre optic connector interfaces ISO 1101:1983, Technical drawings – Geometrical tolerancing – Tolerancing of form, orientation, location and run-out – Generalities, definitions, symbols, indications on drawings
For the purposes of this part of IEC 62148, the following definitions apply. 3.1 base plane plane passing through the lowest plane of the case body that is parallel with the seating plane 3.2 electrical terminal that part of the fibre optic active component or device primarily used for making an electrical connection 3.3 footprint projection of the fibre optic active component or device on the seating plane for mounting purposes NOTE This includes the mounting space on the seating plane as well as positions and sizes of counterpart electrical terminals and mechanical fixtures .3.4 interchangeability feature ensuring that mounting, mating and fixturing 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 also 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
Fibre optic transceiver modules can be classified into different forms according 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 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 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 interface 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 standard. 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.
6 Specifications of electrical interfaces
6.1 General The electrical interface should 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 fibre 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 guarantee 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.
