Cabling specialist converts a concept from nature into production technology and reaches new milestone


Augsburg, May 8, 2019 – Rosenberger Optical Solutions & Infrastructure (Rosenberger OSI), manufacturer of innovative fiber optic cabling infrastructures in Europe, announces the development of the world’s first PreCONNECT® LOTUS – a significant innovation for improving performance in data centers. With PreCONNECT® LOTUS, time-consuming and cost-intensive downtimes due to the complicated cleaning of connector surfaces are a thing of the past. Rosenberger OSI’s unique coating of the fiber optic surfaces acts like the lotus effect in nature: the contact points are dirt, moisture and grease repellent.

“A large part of the disturbances in the fiber optic infrastructure of data centers can be traced back to the contamination of plug connections. Even during installation, soiling due to the adhesion of dust, moisture or grease particles to the contact surfaces can lead to considerable performance problems and a great deal of cleaning effort. With our radical new solution PreCONNECT® LOTUS these problems are a thing of the past. In this way, we ensure a sustainable ‘better world’ in data centers,” says Thomas Schmidt, Managing Director of Rosenberger OSI.

PreCONNECT® LOTUS: High reliability and availability
The reliability and availability of fiber optic networks in data centers can be decisively increased by consistently mastering the “dirt topic”. Operators of cabling infrastructures can now also use the outstanding features of PreCONNECT® LOTUS for their data center and profit from high reliability and availability with simultaneous time and cost savings.

The advantages of PreCONNECT® LOTUS at a glance:

  • Basic avoidance of contamination at fiber optic end surfaces
  • Increased reliability of fiber optic links and improved transmission properties
  • Avoidance of cost-intensive troubleshooting
  • Avoidance of unforeseen downtimes
  • Time savings during the installation of fiber optic cables by eliminating the need for cleaning

New high-tech area at the production site in Hungary
In order to convert intensive research and development work into production technology, a completely new high-tech area for PreCONNECT® LOTUS was integrated into the production site in Taksony. The development was already honored in prototype status, as the product already received the Platinum Level Award in the Cabling Installation & Maintenance Innovators Program 2018 as well as the German Data Center Award 2017.
