18、rO 2 ) PC ferrule optical interface to meet specific requirements for fibre- to-fibre interconnection. Ferrules made from the material specified in this document are suitable for use in categories C, U, E, and O as defined in IEC 61753-1. Ferrule dimensions and features are contained in the IEC 6175

19、4 series of fibre optic connector interface documents. 2 Description The performance of a cylindrical ferrule optical interface 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

20、 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 following: ferrule outside diameter; fibre hole concentricity relative to the ferrule outside diameter; fibre hole angle rel

21、ative to outside diameter axis; fibre cladding diameter relative to fibre hole clearance; alignment sleeve inside diameter; fibre core concentricity relative to the cladding diameter; fibre core orientation relative to keying feature. Parameters influencing the longitudinal offset of the optical fib

22、re axes include the following: end-face spherical radius; end-face spherical radius apex offset; fibre undercut; axial force on ferrule end-face; ferrule and fibre material physical constants; alignment sleeve frictional force.
