PreCONNECT® LOTUS: self-cleaning optical fiber contacts

No more dirty optical fiber links – meaning there are no limits for unhindered data flows!

Many of the malfunctions that occur in optical fiber infrastructures are due to the contamination of connector surfaces. As early as the installation phase, contamination can lead to considerable performance problems and extensive cleaning work due to the adherence of dust, moisture or grease particles on the contact surfaces. With PreCONNECT® LOTUS, time- and cost-intensive downtimes and the extensive work involved in cleaning connector surfaces are history. Following nature's example, optical fiber plug-in connectors equipped with PreCONNECT® LOTUS are fully self-cleaning.

PreCONNECT® LOTUS - The technology that is changing the world.

Nature sets the standard. For a sustainable “better data center world”. Overcoming the issue of contamination in this consistent, logical way vastly increases the reliability and availability of optical fiber networks in data centers. Take advantage of the outstanding properties of PreCONNECT® LOTUS for your data center and benefit from high reliability and availability coupled with time and cost savings.
