Our premium-grade optical fiber assemblies are durable, high-quality patch cords that deliver uniform results with minimal signal variance. Premium-grade patch cords act as both illumination and read fibers and connect easily to Ocean Insight spectrometers, light sources and sampling accessories.

UV radiation <300 nm degrades signal transmission in standard silica fibers, resulting in solarization (increased light absorption in the UV that can invalidate measurements). Solarization-resistant fiber assemblies use polyimide or aluminum buffers that mitigate the effects of UV degradation.



  • Resistance to UV effects -- polyimide or aluminum buffers mitigate UV transmission degradation
  • Jacketing options -- stainless steel BX or silicone-coated steel monocoil with a Nomex braid 
  • Variety -- assemblies available in different core diameters and lengths; custom options also available
  • Convenient handling -- precision SMA 905 connectors with extra-long knurled ferrules for easy manipulation
  • Robust -- great for field and industrial use, or other rough handling environments
