IEC 61754-12:1999 pdf download – Fibre optic connector interfaces -Part 12: Type Fs connector family.
This part of IEC 61754 defInes the standard Interlace dimensions for the type FS Connector family.
2 DescrIption
The parent connector for the type FS connector family Is a duplex connector set of plug and adaptor configuration. The plug has a pair of cylindrical spring loaded abutting ferrules of 2.5 mm nominal ferrule diameter. The optical alignment mechanism is a rigid bore or resilient sleeve contained within the adaptor. It includes a hand-released latch coupling. The plug has multiple keyway arrangements and the adaptor has multiple key configurations. The keying scheme is exclusionary and is used to limit mating between plug and adaptor to specific key combinations.
