31、s part of IEC 61754 defines the standard interface dimensions for type MPO family of connectors. 2 Description The parent connector for type MPO connector family is a multiway plug connector charac- terized by a rectangular ferrule normally 6,4 mm ? 2,5 mm which utilizes two pins of 0,7 mm diameter
32、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. 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
33、key which may be used to orient and limit the relative position between the connector and the component 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 t
34、he male plug. 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. Connector interfaces with different numbers of optical datum targets will intermate and will correctly align the l
35、ower defined numbers of optical datum targets. 3 Interfaces This standard contains the following standard interfaces.

NOTE 2 Dimension C is 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
