GR 50/125-23-HTA

50 µm Multimode Radiation Resistant Fiber

Nufern’s specialty multi-mode fibers are ideal for a variety of diverse applications. They are capable of withstanding extreme environments and large temperature swings. Features include step index and graded index configurations, numerical apertures from 0.06 to 0.45 and core sizes from 10 μm to 700 μm. All fibers are available with a high temperature acrylate, silicone, or polyimide coating.
Applications
  • Telecom FDDI, FTTH, etc.
  • Optical pump & beam delivery
  • Robust duty in extreme environments
  • CATV and data comm.
Features & Benefits
  • Operate over wide frequency range — One fiber serves broad applications
  • Exceptional uniformity and core/clad concentricity — Minimize fiber induced signal artifacts
  • Higher proof test levels — Longest life expectancy
  • Tight diameter control — Lowest cost deployments
