What is BS EN 61755-3-7 - Fibre optic interconnecting devices and passive components about?
BS EN 61755 is a series on fibre optic interconnecting devices and passive components. Fibre optic interconnecting devices and passive components do not require electrical-to-optical or optical-to-electrical conversion during their operation. BS EN 61755-3-7 defines dimensional limits and material properties of a 2,5 mm and a 1,25 mm diameter cylindrical composite ferrule optical interface to meet specific requirements for PC fibre-to-fibre interconnection. The composite ferrule uses different materials in the end face contact zone and in the ferrule to sleeve contact zone. The specified materials for each zone are zirconia (ZrO2) for the ferrule to sleeve contact zone and titanium for the end face contact zone. Ferrules made from the material specified in BS EN 61755-3-7 are suitable for use in categories C, U, E and O as defined in IEC 61753-1.
Who is BS EN 61755-3-7 - Fibre optic interconnecting devices and passive components for?
BS EN 61755-3-7 on fibre optic interconnecting devices and passive components is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 61755-3-7 - Fibre optic interconnecting devices and passive components?
Fibre optic interconnecting devices and passive components are widely used by people as a promising solution for modern access to telecommunication networks. BS EN 61755-3-7 describes the performance of a cylindrical ferrule optical interface that is determined by the accuracy with which the optical datum targets of two mating ferrules are aligned with each other. There are three conditions affecting the alignment of two optical datum targets, lateral offset, angular offset, and longitudinal offset.
Parameters influencing the lateral and angular offset of the optical fibre axes include the ferrule outside diameter, fibre hole concentricity relative to the ferrule outside diameter, fibre hole angle relative to outside diameter axis, fibre cladding diameter to fibre hole clearance, alignment sleeve inside diameter, fibre core concentricity relative to the cladding diameter and fibre core orientation relative to keying feature. Parameters influencing the longitudinal offset of the optical fibre axes include the end face spherical radius, the end face spherical radius apex offset, fibre undercut, axial force on the ferrule end face, ferrule and fibre material physical constants and the alignment sleeve frictional force. Using BS EN 61755-3-7 you can define dimensional limits and material properties of a 2,5 mm and a 1,25 mm diameter cylindrical composite ferrule optical interface to meet specific requirements for PC fibre-to-fibre interconnection.
