What is BS EN 61755-3-5- Cylindrical composite ferrule optical interface about?
BS EN 61755-3-5 is a part of a multi-series International Standard that covers the aspects of good quality fibre optic connector optical interfaces.
BS EN 61755-3-5 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.
Ferrules made from the material specified in BS EN 61755-3-5 are suitable for use in categories C, U and O as defined in IEC 61753-1. The composite ferrule uses varied 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 Cu-Ni-alloy for the end face contact zone.
Note: If mated within the same family (cylindrical PC ferrule) the ferrules specified in BS EN 61755-3-5 are intended to have the same optical attenuation performance grade for connections with all ferrules described in IEC 61755-3 standards.
Who is BS EN 61755-3-5- Cylindrical composite ferrule optical interface for?
BS EN 61755-3-5 on cylindrical composite ferrule optical interface is relevant to:
- Manufacturers of fibre optic connector optical interfaces
- Manufacturers of fibre optic components
- Regulatory authorities
- Fibre optic technicians
- Fibre optic installers
- Testing authorities
Why should you use BS EN 61755-3-5- Cylindrical composite ferrule optical interface?
The performance of a cylindrical composite ferrule optical interface is determined by the accuracy with which the optical datum targets of two mating ferrules are aligned with each other.
BS EN 61755-3-5 presents you with the specifications for cylindrical composite ferrule optical interfaces and the parameters influencing their performance. It states the three conditions affecting the alignment of two optical datum targets, which are, lateral offset, angular offset, and longitudinal offset.
BS EN 61755-3-5 covers parameters influencing the lateral, angular offset, and the longitudinal offset of the optical fibre axes as well. It gives the figures depicting optical interface dimensions as well as highlights fibre core location. This helps the users to manufacture the optical interfaces that are following the standard specifications and help them mitigate the defects in the products.
Overall, BS EN 61755-3-5 is useful as it provides guidance on 2.5 mm and 1.25 mm diameter cylindrical PC composite ferrule using Cu-Ni-alloy as fibre surrounding material, single-mode fibre, which can be helpful for your business.
