Hermetic adapter up to 30 bars

The KTRAV-IP series is a hermetic adapter for pressure applications up to 30 bars.

It can be seen as a simplified feedthrough that does not integrate any fiber inside the body. It is a hermetic adapter that allows to hermetically connect two optical fiber patch cords terminated with SMA, ST/PC or ST/APC connectors. Both sides
must remain connected to maintain seal integrity.

Indeed, the SMA and ST coupling parts feature an integral self-sealing design that ensures a watertight, environmentally, and hermetically sealed fiber connection. Hence, the KTRAV-IP adapter, when connected to the fiber patch cord, can reach a hermeticity of 10-5 mbar.l/s. Besides, it can withstand a pressure level of up to 30 bars. As a result, the connected optical fiber is completely protected from the surrounding environment.

The panel hermeticity is obtained by a gasket in the flange while the inner hermeticity is obtained by a gasket on the connector ferrule.

This hermetic adapter is supplemented by specific ruggedized SMA or ST connectors and dust caps.

We also offer a variety of compatible patch cords separately. The SMA version supports fiber patch cords from 200 µm to 1500 µm core diameters terminated with in-house SMA connectors equipped with a Viton O-ring. The ST versions are compatible with any patch cords up to 1000 µm and terminated with standard ST connectors.
