22、 AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 26: Type SF connector family 1 Scope This part of IEC 61754 defines the standard interface dimensions for the type SF optical board connector that uses a normal glass fibre and the physical contact technique to connect flexible optical bo
23、ards and ribbon fibres. 2 Description The parent connector for the type SF connector family is a multiway connector with a plug/socket connector set configuration, The plug is characterized by multiway cantilevered optical fibres located inside the plug, The plug optical fibres buckled to mate with
24、the socket optical fibre ends, Mating socket optical fibres are positioned and aligned by using multiway micro holes, Socket micro holes capture, guide, and align the plug optical fibres during connector set engagement, The plug fibres and socket fibres are butted together to realize physical contac
25、t connection by employing the buckled force of the plug fibres without using a ferrule or a spring, 3 Interfaces This standard contains the following standard interfaces, IEC 61754-26-1: SF plug connector flat interface for 2 to 16 fibres IEC 61754-26-2: SF socket connector flat interface for 2 to 1
26、6 fibres The following connectors are intermateable: IEC 61754-26-1 mates with IEC 61754-26-2 Figure 1 is an example of a SF plug connector interface.
