Introduction
This family of fibre optic contact sub-assemblies are suitable for use in ARINC 600 connectors with
size 8 Quadrax cavities in aerospace onboard applications. It provides easy access for optical contact end
face cleaning.
1 Scope
This standard specifies the general characteristics, the conditions for qualification, acceptance and quality
assurance, as well as the test programs and groups for fibre sub-assembly contact in rack and panel
connectors, intended for use in a temperature range from − 65 °C to 125 °C continuous (cable dependent).
This standard specifies a pair of adaptors to fit with standard Quadrax cavities and EN 4531-101 optical contact.

4 Description
4.1 Optical sub-assembly and adaptor
The optical sub-assembly comprises of an EN 4531-101 fibre optic contact, male and female adaptors
allowing positioning of the fibre optic contact in either a plug or receptacle Quadrax size 8 cavity or a single
part which integrates the EN 4531-101 contact and adaptor.
The female adaptor is characterised by the integral alignment sleeve providing precise alignment of the optical
ferrules.
The optical contact sub-assemblies are polarized by means of keyways in the adaptors and keys on the
contact body.
4.2 Materials and surface treatment
4.2.1 Requirements
When dissimilar metals are in close contact, adequate protection against corrosion shall be used for the
electromotive force of the cell not to exceed 0,25 V (see EN 3197).
4.2.2 Housing and inserts
The connector housing and insert arrangement information are detailed in ARINC 600 standards.
4.2.3 Optical contacts
Details of the optical contacts and alignment sleeves are detailed in EN 4531-101.
4.2.4 Adaptor
The adaptor shall be of suitable material as specified in the product standard.
5 Design
5.1 Housing
Connector housing is defined in the ARINC 600 standard. Quadrax cavity arrangements will be defined in
Technical Report in preparation.
5.2 Optical contact
See EN 4531-101.
5.3 Adaptor
The adaptor is designed to provide mechanical 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 contacts without removal of the connertor insert.
Fitting and removal of the adaptor will be from the rear of the connec
