Since its establishment in 1995, NETWORK GROUP operates as a distributor of structured and optical wiring system. In 2000, it expanded its activities into the area of printed circuit boards. Apart from its business and production activities, the company founded its research and technological department for projects, research and development of advanced optical fiber elements which are used especially in advanced industrial applications.

NETWORK GROUP, department of special fibre optics, is focused on the in-house design, development and production of versatile sensor systems based on FBG (Fibre Bragg Grating), using a team of specialists and high-tech equipment. The main area of interest is the measurement and monitoring of critical infrastructures where deformation, strain and temperature profiles or vibrations are required. Typical applications include Bridges, Nuclear Power Plants, Silos for storage of bulk or chemical materials, advanced industrial applications and Railway traffic.

Main activities:

• Complex sensors systems for measurement and monitoring of temperature, deformations, strain, vibrations, etc.
• Structure health monitoring
• Systems for strain and temperature measurement of containment for nuclear power plants
• Temperature measurement in industrial and chemical silos and other special applications
• Measurement, monitoring and diagnostics of reinforced concrete structures, especially bridges.
• Railway monitoring
