| 17 | Annex D (normative) Minus co-planarity and fibre plane angle determination D.1 Scope D.1.1 Minus co-planarity The absolute distance between the best fit plane (or line in the case of single row ferrules) of the fibre ends (the average elevation of the averaging regions) and the lowest fibre end. The two planes are to be oriented parallel to a best fit plane … D.1.2 Fibre plane X and Y angle The relative tilt of the best fit plane of D.1.1 relative to the guide pin bores. D.2 Method for Analysis D.2.1 Single Row Ferrules D.2.1.1 Create an array of X and Y values where X is the fibre X location and Y is the fibre height determined in clause 5.2.10. Fit a least squares line to this data y(x). Calculate the array minus-coplanarity as: D.2.1.2 Calculate the X angle of the least squares fit line (the fibre plane) using a line perpendicular to the guide pin bores as a reference.

| 18 | Annex E (normative) E.1 Scan each individual fibre endface surface and find the fibre line (or the fibre plane in case of a multi-row ferrule). This is the same line (or plane) as used in the co-planarity algorithm (Annex D) E.2 Fit to each fibre endface surface points located inside zone CD a paraboloid function of type E.3 For each fibre, the coredip CD = 450 * (A+B) See below for details |
