22、E OPTIC CONNECTOR INTERFACES Part 7: Type MPO connector family1ScopeThis part of IEC 61754 defines the standard interface dimensions for type MPO family of connectors.2DescriptionThe parent connector for type MPO connector family is a multiway plug connector charac- terized by a rectangular ferrule
23、normally 6,4 mm 2,5 mm which utilizes two pins of 0,7 mm diameter as its alignment. It is applicable to a joint of multiple fibres up to 12 fibres by arraying them between two pin-positioning holes in the ferrule. Furthermore, it is capable of joining up to24 fibres by arraying them with a two layer
24、 arrangement. The connector includes a push-pull coupling mechanism and a ferrule spring loaded in the direction of the optical axis. The connector has a single male key which may be used to orient and limit the relative position between the connector and the component to which it is mated.Connector
25、 interfaces are configured using a female plug without pins, a male plug with pins fixed and an adaptor as shown in Figure 1. The female plug is intermateable with the male plug.Moreover, connector interfaces between the female plug and the male plug are configured by applying a backplane housing an
26、d a printed board housing instead of the adaptor.3InterfacesThis standard contains the following standard interfaces:Interface 7-1:MPO female plug connector angled interface Push/pull consisting of: Interface 7-1-1 for 2 to 12 fibresInterface 7-1-2 for 16 to 24 fibresInterface 7-2:MPO male plug conn

In addition, two pin-holes 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
34、 defined as the distance between two pin-hole 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 compression force, and therefore dimension I is variable. Ferrule compression force must be 7,8 N to 1
35、1,8 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 compression force. Dimension L is given for a coupling sleeve end when not mated. Coupling sleeve compression force must be 2,9 N to 6,9 N when a
36、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 left-direction movement of a coupling sleeve, when it is separate from an adaptor. W hen the coupling sleeve is moved fo
37、r unlocking, a position of the coupling sleeve endface must be larger than 2,0 mm in the left direction from the datum Z.0,1250,125X0,1250,3750,375X0,1250,1250,3750,6250,8750,3750,6250,875YYYX0,1250,125Two fibresFour fibresEight fibres0,1250,3750,6250,3750,6250,8751,1250,8751,1250,1250,1250,3750,6250,8751,1251,3750,3750,6250,8751,1251,375Y YXTen fibresTwelve fibresIEC 1594/04XFigure 3 Optical datum target location diagrams (1 of 2)0,2500,2500,1250,125X0,2500,2500,3750,6250,8750,3750,6250,8750,1250,1250,3750,6250,
