Plug and receptacle housings conform to EN 4165-001. The connectors use rear removable optical contacts with a ferrule diameter of 2,5 mm in accordan

18、ce with EN 4531-101. The precise alignment of the optical contacts is accomplished by a central alignment pin/socket and alignment sleeves. The receptacles and plugs contain either male or female module. The male module is characterised by alignment pin. The inserts can be installed and removed from

19、 the shell by mean of a tool as specified EN 4165-022. Keying system conform to EN 4165-001. Connector type designation as specified in EN 4165-001.

The module is mechanically held in the connector housing by retention clips, and removable with the use of an extraction tool. The mechanical contacts retention system shall be integrated

25、 in the hard module. The front face of the module shall be such that sealing is ensured when the connectors are coupled. The interfacial seal shall be permanently fastened on the male module. Sealing of the rear face of the module is provided by the contact boot. The design shall permit individual i

26、nstallation of the contacts without removal of the module. Insertion and removal of the contacts shall be from the rear. For ease of operation, tools as per MIL-I-81969/14-04 standard (P/N for size 12) may be used. Contact identification shall be permanent and contrasted on the rear face of the inse
