In addition, two pinholes of a plug must accept a gauge as shown in Figure 5 to a depth of 5,5 mm with a maximum force of 3,4 N. NOTE 2 Dimension C is defined as the distance between two pinhole centres. NOTE 3 Dimension I is given for a fibre endface centre of a plug end when not mated. It is noticed that a ferrule is movable by a certain axial pression force, and therefore dimension I is variable. Ferrule pression force must be 7,8 N to 11,8 N when a position of the fibre endface from the datum Z is in the range of 8,2 mm to 8,4 mm. NOTE 4 Coupling sleeve must be movable by a certain axial pression force. Dimension L is given for a coupling sleeve end when not mated. Coupling sleeve pression force must be 2,9 N to 6,9 N when a position of the coupling sleeve endface from datum Z is in the range of 0 mm to 0,1 mm to the right or to the left of datum Z. NOTE 5 An adaptor coupling part must be unlocked by a leftdirection movement of a coupling sleeve, when it is separate from an adaptor. W hen the coupling sleeve is moved for unlocking, a position of the coupling sleeve endface must be larger than 2,0 mm in the left direction from the datum Z. – 8 – BS EN 617547:2020 X X 0,125 0,125 0,125 0,125 0,375 0,625 0,375 0,625 0,875 1,125 0,875 1,125 X 0,125 0,125 0,375 0,375 X 0,125 0,125 0,375 0,625 0,875 1,125 1,375 0,375 0,625 0,875 1,125 1,375 X 0,125 0,125 0,375 0,625 0,875 0,375 0,625 0,875 Y Y Y Two fibres Four fibres Eight fibres Y Y Ten fibres Twelve fibres IEC 1594/04 Figure 3 – Optical datum target location diagrams (1 of 2) – 9 – BS EN 617547:2020 0,125 0,125 0,125 0,125 X X 0,375 0,625 0,875 1,125 1,375 0,375 0,625 0,875 0,375 0,625 0,875 1,125 1,375 0,375 0,625 0,875 0,125 0,125 X 0,375 0,625 0,875 1,125 0,375 0,625 0,875 1,125 0,250 0,250 0,250 0,250 Y Y Sixteen fibres 0,250 0,250 Twenty fibres Y Twenty four fibres IEC 1595/04 NOTE The optical datum target location diagram is shown in the figure.
