23、NTERFACES Part 7: Type MPO connector family 1 Scope This 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 m
24、m 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 to 24 fibres by arraying them with a two layer arrangement.
25、 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 interfaces
26、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 and a printed
27、 board housing instead of the adaptor. 3 Interfaces This 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 fibres Interface 7-1-2 for 16 to 24 fibres Interface 7-2: MPO male plug connect
