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

Visible-NIR patch cords are low OH fibers that transmit most efficiently from 400-2100 nm. UV-Visible (300-1100 nm) and solarization-resistant (180-800 nm and 200-1100 nm) options are also available.


  • Visible-NIR transmission -- low OH fibers transmit best from 400-2100 nm
  • 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 lab, field and industrial use
