4 Description

4.1 General

This document describes an optical connector insert to be installed in plug and receptacle housings

Plug and receptacle housings conform to ARINC Specification 600

The precise alignment of the optical contacts is accomplished by alignment sleeves held in a removable sleeve holder

The plug connector contain male insert as specified in EN 4640-003

The receptacles connector contain female insert as specified in EN 4640-004

The female insert is composed of an insert and a removable sleeve holder as specified in EN 4640-004

The sleeve holder is delivered with the female insert It is considered as a part of the female insert (specific design per manufacturer)

The sleeve holder can be supplied separately only for repair purpose

The optical contact is in accordance with EN 4639-101

The connectors are keyed as specified in ARINC Specification 600
