Fiber optical bundles and cross-section converters

Optical waveguide with large cross-section and small bending radius

Manufacture of customer-specific bundle designs, such as multi-branched optical fibers and cross-section converters with a round-to-linear fiber configuration.

  • Development, design, and manufacture of raw material, fibers, bundles, cables and assemblies, as well as optical special components and probes – all from a single source
  • Suitable for difficult environmental conditions and harsh industrial surroundings
  • Suitable for liquids, gases, or solids

Range of products and services

Product portfolio

  • Fiber bundles with single fiber diameters of
    20 µm to 105 µm (fiber bundles with larger single fiber diameters are possible)
