10、ication. prEN 4531-001:2014 (E) 3 Introduction This family of fibre optic connectors coupled by triple start threaded ring is derived from MIL-DTL-38999L series III and EN 3645-001. It is suitable for use on aerospace on-board applications. Two variants of female insert are defined: Flush variant (A
11、-Type female insert) is only possible with multimode contact. Recessed variant (B-Type female insert) is required for single mode contact. The optical contacts are capable of accepting single cable sizes up to a maximum of 1,9 mm outside diameter. prEN 4531-001:2014 (E) 4 1 Scope This standard speci

The receptacles and pl
22、ugs contain either male insert or female insert. The female insert is characterized by its ability to precisely align the optical contacts. The precise alignment of the optical contacts is accomplished by alignment sleeves. The connectors are polarized by means of keyways and keys; polarization is o
23、btained before the male contacts enter the insert of the female contacts and before the coupling ring is engaged. The position of the keying arrangement is given in 6.4. The connectors with shell size 9, 11 and 13 are 100 % scoop proof. The visual check of full mating is obtained by masking of a red
24、 coloured band on the receptacle. 4.2 Receptacle The receptacle contains five keyways in which the keys of the plug engage. The main keyway is fixed and is wider than the others. Polarization is ensured by the different positions which the secondary keyways may take. The position of the insert is fi
