Usage:

The cables are used for transmission of optical signals for indoor and outdoor environment where is insisted on personal protection, on the protection of equipments, constructions and of materials (e.g. in public spaces, shopping malls, in hospitals, hotels or in tunnel constructions).

The cables can be placed in the environment with the explosion danger (zone 1, 2) providing compliances with the conditions of intrinsic safety according to IEC 60079-11.
