Key features and benefits


8D ELIO range is 38999 sIII circular type connectors with insert for ELIO optical contact. It is used by Airbus as a standard on aircraft programs like A380, A350, A330 for all the communication using fiber optic.

The flight proven ELIO® fiber optics termini are designed around a robust 2.5mm ceramic ferrule. The assembly is as easy an ST connector. The insertion and retention inside the connector is ensured by a bayonet locking mechanism without any special tool. The termini integrates a seal inside the rear boot, thus the connection is sealed from the rear side without a backshell or a grommet. The 8D ELIO® range covers layout from 1 to 24 ways in all type of material shell.

Each cavity can be upgraded with the brand-new ELIOBEAM expanded beam ELIO® version.

In the female insert, the termini are flushed to the insert surface, thus making easy the fiber optical end-face inspection and cleaning, compared to the traditional dust collecting socket design.

The same termini part number can adapt tight or loose structure cable.
