22、 OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 7-1: Type MPO connector family One fibre row 1 Scope This part of IEC 61754 defines the standard interface dimensions for type MPO family of connectors with one row of fibres. 2 Description The parent connect
23、or for type MPO connector family is a multiway plug characterized by a rectangular ferrule normally 6,4 mm 2,5 mm which utilizes two pins of 0,7 mm diameter as its alignment. The variant in this standard provides a joint of 2 to 12 fibres by arraying them between two pin-positioning holes in the fer
24、rule in a one-layer, (one-row) 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
25、to which it is mated. Connector 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. There are two angled-interface plugs, one called down-angled and the other up-angled. They
26、 are defined for both male and female plugs. The up and down descriptors refer to the tilt direction of the ferrules angled end-face relative to the fibre axis when looking toward the end-face with the plugs key feature on the top. For down-angled plugs, the angled surface faces slightly downward. F
27、or up-angled plugs, the angled surface faces slightly upward. These different angles affect intermateability for the two adaptor types. An opposed keyway adaptor mates two plugs with the keys in opposite orientations, for example one side keyway-up and the other keyway-down. In contrast, an aligned
28、keyway adaptor mates two plugs with the keys at the same orientation. When using an opposed keyway adaptor with angled interfaces, two down-angled plugs or two up-angled plugs are connected. For aligned keyway adaptors with angled interfaces, one down-angled plug and one up-angled plug are connected
29、. Moreover, connector interfaces between the female plug and the male plug are configured by applying a backplane housing and a printed board housing instead of the adaptor. Additionally, the female plug interface is intermateable with the active device receptacle. 3 Interfaces This standard contain

In add
39、ition, two pin-holes of a plug shall accept a gauge as shown in Figure 5 to a depth of 5,5 mm with a maximum force of 3,4 N. bDimension C is defined as the distance between two pin-hole centres. cDimension I is given for a fibre endface centre of a plug end when not mated. It is noticed that a ferru
40、le is movable by a certain axial compression force, and therefore dimension I is variable. Ferrule compression force shall 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. dThe coupling sleeve shall be movable by a certain axial compressio
41、n force. Dimension L is given for a coupling sleeve end when not mated. Coupling sleeve compression force shall be 2,9 N to 6,9 N when the 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. eAn adaptor coupling part shall be
42、 unlocked by a left-direction movement of a coupling sleeve, when it is separate from an adaptor. When the coupling sleeve is moved for unlocking, the position of the coupling sleeve endface shall be larger than 2,0 mm in the left direction from the datum Z. f Dimension I is defined at the centre li
43、ne between the two pin-hole centres. gThe mating/unmating force between an MPO plug and adaptor shall not exceed 30,0 N. h Dimensions D1 and U1 are defined only at the end of the plug as shown. i The down-angled and up-angled plugs shall be clearly marked to distinguish them from each other and flat
44、 interfaces through the use of colour, labelling or other appropriate identification method. This identification method shall be visible when the plug is in the mated or unmated condition. j Since angled MPO plugs require a Y-offset of the fibre holes in relation to the guide pin holes, and the Y-of
45、fset is referenced from the epoxy window of the ferrule, the angle shall be polished as a down-angle from the epoxy window. The orientation of the ferrule epoxy window may be reversed in the MPO plug to produce the up-angle variant. Figure 4 shows optical datum target location diagrams. Figure 5 sho
