Fiber optical bundles and cross-section converters

Fiber optical bundle assemblies

Fiber optical bundle assemblies

Optical fiber with a large cross-sectional area and a small radius for bending.

Creation of customized bundle layouts, including options like multi-branched optical fibers and converters for cross-sections from round to linear fiber designs.

  • Comprehensive development, design, and production of raw materials, fibers, bundles, cables, assemblies, as well as specialized optical components and probes – all offered by a unified provider
  • Designed to withstand challenging environmental conditions and severe industrial environments
  • Applicable for use with various substances, including liquids, gases, and solids
