22、anical retention, and accurate alignment of the EN 4531-101 fibre optic contact within an ARINC 600 housing containing Quadrax size 8 cavities. The adaptor is keyed and mechanically retained in the ARINC 600 Quadrax size 8 insert cavity. The design permits installation of individual adaptors and con

23、tacts without removal of the connertor insert. Fitting ant removal of the adaptor will be from the rear of the connector insert using the tool specified in the relevant adaptor product standard. prEN 4626-001:20065 5.4 Connector and optical contact coupling sequence During normal coupling the mechan
