28、ibes an optical connector module to be installed in plug and receptacle housings. Plug and receptacle housings conform to EN 4644-001. There are two sizes of connector housings: Housing size 1 with 1 module cavity. Housing size 2 with 2 module cavities. The connectors use rear removable optical cont
29、acts with a ferrule diameter of 1,25 mm. The precise alignment of the optical contacts is accomplished by alignment sleeves held in a removable sleeve holder. The receptacles and plugs contain either male or female module. The female module is characterised by its ability to receive the removable sl
30、eeve holder. The modules can be installed and removed from the shell by means of a tool as specified in EN 4644-003. The modules are keyed to prevent mismatching (“A” module for connector housing cavity “A” and “B” module for connector housing cavity “B”) as specified in EN 4644-001. The connectors
31、are keyed as specified in EN 4644-001.

35、-001. 5.2 Modules The modules carrying the optical contacts shall be in hard material and have a cross section and radii such that no cracks, flaking or breaks can occur in normal operation. The contact module is mechanically held in the connector housing by retention clips, and removable with the u
36、se of an extraction tool. The mechanical contacts retention system shall be integrated 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 of the module of the male contacts shall be permanently fastened on the
37、hard module. Sealing of the rear face of the module is provided by a grommet adapted to the external diameter of the cable. The design shall permit individual installation of the contacts without removal of the module. Installation and removal of the contacts shall be from the rear. For ease of oper
38、ation, tools as per MIL-I-81969/14-03 standard (P/N for size 16) may be used. Contact position identification shall be permanent and contrasted on the rear face of the insert or grommet. 6 Definition drawings 6.1 General The general dimensions and the masses of receptacles, plugs and protective cove
