Fibre optic interconnecting devices and passive components – connector optical interfaces – part 3-8: Connector parameters of non-dispersion shifted single mode physically contacting fibres – angled 2,5 mm and 1,25 mm diameter cylindrical composite ferrules using titanium as fibre surrounding material

This part of IEC 61755 defines dimensional limits of an optical connector with a 2,5 mm and a 1,25 mm diameter cylindrical composite ferrule using titanium as fibre surrounding material for optical interface to meet specific requirements for angle polished fibre-to-fibre interconnection as defined in IEC 61755-2-1. The composite ferrule uses different materials in the end-face contact zone and in 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 this document are suitable for use in all operating service environments categories defined in IEC 61753-1. This part of IEC 61755 defines dimensional limits as well for optical connector with a 2,5 mm and a 1,25 mm diameter cylindrical composite ferrule used as reference interface. NOTE If mated within the same family (cylindrical APC ferrule), the ferrules specified in this standard are intended to have the same optical attenuation performance grade for connections with all ferrules described in different parts of IEC 61755-3 series documents. © IEC:2021.
