Introduction
The family of connectors used in this document is in accordance with EN 3645-001. The optical termini,
which are using the expanded beam technology, are specially adapted to the cavities of this kind of
connectors. It is particularly suitable for use in zones of severe environmental conditions on board
aircraft, applying EN 2282.
1 Scope
This document specifies the general characteristics, the conditions for qualification, acceptance and
quality assurance, as well as the test programs and groups for threaded ring coupling circular
connectors with expanded beam termini, intended for use in a temperature range from −55 °C to 125 °C
continuous.
