Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions. CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech Sweden, Switzerland and the United Kingdom.

The composite ferrule uses different materials in the end face contact zone and in theferrule to sleeve contact zone.The specifiedmaterials for each zone are Zirconia (ZrO2) for the ferrule to sleeve contact zone and Cu-Ni-alloy for the end face contact zone. Ferrules made from the material specified in this document are suitable for use in categories C, UandO as defined in IEC 61753-1. NOTE If mated within the same family (cylindrical PC ferrule) the ferrules specified in this document are intended to have the same optical attenuation performance grade for connections with all ferrules described in IEC 61755-3 documents. 2 Description The performance of a cylindrical ferrule optical interface is determined by the accuracy with 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 ferrule
