Optic fibre networks

We pay a lot of attention to fibre optic cabling - single mode and multimode fibres. We have the state-of-the-art devices for welding optic fibres and optic route measurement with the direct method and the OTDR method. Such equipment allows us to build and service optic routes on all types of optic fibres.

Metallic cabling

As to metallic technology, we design and install cabling in compliance with the latest standards.
On a standard basis, we deliver cabling in both unshielded and shielded version, within the performance range of classes D, E and F, according to the standards for universal cabling.
For certification we use the latest measuring devices.

Design works

  • Design and consulting in the field of structured cabling construction
  • Preparation of as-built documentation
  • Preparation of assessment of existing metallic cabling based on measurement

 

Installation and assembly works

  • Installation of metallic components such as by Tyco Electronics-AMP, Molex Company, SYSTIMAX Solutions and Schrack
  • For certifications we use the latest measurement devices by FLUKE, Agilent Technologies and HEWLETT PACKARD .
