BKS meets CERN...

CERN, the European Organization for Nuclear Research, is a major research centre at Meyrin in the Geneva canton. At CERN basic physical research is carried out, in particular the structure of matter is researched with the help of large particle accelerators. Currently the most important one is the «Large Hadron Collider», which was put into operation in 2008.

At CERN one of the largest local fibre networks was installed. BKS acted as subcontractor of the consortium EMTE/ DRAKA and provides all the fibre-optic connection technology.

The redundantly designed network has an overall length of 1'500 kilometres. It passes through the tunnel and not only connects with one another the eight research­stations along the 27 km ring system but also the locations above ground. The fibre-glass ­cabling plays a very important role in the process because here in real time trans­mission of measured values and the synchronization of the particle­ acceleration are carried out. The synchronization may deviate by only a few billionths of a second. That is why the optical fibre­ compounds must not only display ­extremely good damping characteristics but also have very narrow length­ tolerances in order to avoid any runtime ­problems.

Currently, CERN consists of 21 member states. With over 3'200 employees, CERN is the world's largest research centre in the field of particle physics. More than 10'000 guest scientists from 85 nations are working on CERN experiments.
