31、O 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 as its alignment. It is applicable to a joint of multi

32、ple fibres up to 12 fibres by arraying them between two pin-positioning holes in the ferrule. Furthermore, it is capable of joining up to 24 fibres by arraying them with a two layer arrangement. The connector includes a push-pull coupling mechanism and a ferrule spring loaded in the direct

33、ion 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 interfaces are configured using a female plug without pins, a male plug with pins fixed and an ad

34、aptor 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 and a printed board housing instead of the adaptor. 3 Interfaces This standard contain
