【正文】 ng 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 movement away from the adaptor of a coupling sleeve, when it is separate from the 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. – 18 – BS EN 617547:2020 ?A C D ?E ?F ?G ?H S ?BA U X Z ?0,002 W K I J AC AB R Q P O Guidepin N Y AA L Coupling sleeve M W Guidepin See Figure 3 BB CA IEC 400/08 Figure 9 – MPO male plug connector flat interface – 19 – BS EN 617547:2020 Table 7 – Dimensions of the MPO male plug connector flat interface Reference Dimensions Notes Minimum Maximum A C D E F G H I J K L M N O P Q R S U AA AB AC BA BB CA 0,697 mm 4,597 mm 6,3 mm 8,34 mm 9,49 mm 10,85 mm 12,19 mm 8,8 mm 7,9 mm 1,4 mm 0,2 mm 2,4 mm 2,8 mm 4,89 mm 5,59 mm 5,7 mm – 2,9 mm 2,4 mm 42176。 45176。 1 NOTE 1 Dimension L is the distance from datum Z to a latchledge end.

Surface roughness Rz must be below 0,5 μm. NOTE 2 Dimension C is defined as the distance between two guidepin 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 the 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. NOTE 6 The top shape of guidepin may be a round shape that is symmetrical about the guidepin axis with a minimum radius of 0,15 mm. – 14 – BS EN 617547:2020 S ?H ?W ?F V V ?E R P O X N Z I A AB B B K AA A Keyways opposed L M Section AA Section BB IEC 398/08 Figure 7 – MPO adaptor interface – 15 – BS EN 617547:2020 Table 5 – Dimensions of the MPO adaptor interface Reference Dimensions mm Notes Minimum Maximum E F H I K L M N O P R S V W X AA AB 8,54 mm 9,6 mm 12,6 mm 8,2 mm – 0 1,6 mm 2,4 mm 5,0 mm 5,7 mm 7,8 mm 3,4 mm 0,95 mm 11,8 mm 3,4 mm 45176。 45186。 0,2 mm 0,2 mm 1,6 mm 0,699 mm 4,603 mm 6,5 mm 8,54 mm 9,59 mm 11,05 mm 12,59 mm 9,2 mm 8,1 mm – 0,8 mm 2,6 mm 3,0 mm 4,99 mm 5,69 mm – 7,7 mm 3,1 mm 0,8 mm 2,5 mm 45186。 1 2 3 4 and 5 NOTE 1 Each pinhole must accept a gauge pin as shown in Figure 4 to a depth of 5,5 mm with a maximum force of 1,7 N. 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.
