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 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 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 and 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 connector angled interface Push/pull consisting of: Interface 7-2-1 for 2 to 12 fibresInterface 7-2-2 for 16 to 24 fibresInterface 7-3:MPO adaptor interface Push/pullInterface 7-4:MPO female plug connector flat interface Push/pull consisting of: Interface 7-4-1 for 2 to 12 fibresInterface 7-4-2 for 16 to 24 fibresInterface 7-5:MPO male plug connector flat interface Push/pull consisting of: Interface 7-5-1 for 2 to 12 fibresInterface 7-5-2 for 16 to 24 fibresInterface 7-6: MPO backplane housing interface Self-retainingInterface 7-7: MPO printed board housing interface Self-retainingInterface 7-8: MPO adaptor interface Push/pull, aligned key configurationThe following standards are intermateable:Female plugs7-1-1Adaptors/housings7-3Male plugs7-2-17-1-27-37-2-27-4-17-3 and 7-87-5-17-4-27-3 and 7-87-5-27-1-17-6 and 7-77-2-17-1-27-6 and 7-77-2-27-4-17-6 and 7-77-5-17-4-27-6 and 7-77-5-2NOTE Connector interfaces among 2 to 12 fibres will intermate and will correctly align the lower defined numbers of optical datum targets.
