Reduced Diameter SM Specialty Fibers - Operating at 1520nm - 1650nm

  • 125/245μm fiber for SM transmission from 450nm - 1750nm
  • 80/170μm fibers for high reliability, small form-factor telecom components
  • Ultra-low & low profile, bend-insensitive fiber for de-polarized FOGs, acoustic sensors & small form-factor sensor components
  • High NAs for enhanced bend-insensitivity
  • High Ge content offering intrinsic photosensitivity for FBG inscription without hydrogenation

Typical Applications:

  • Hydrophones/Geophones
  • Telemetry
  • Down-link fibers
  • FBGs
  • DTS/DAS/DSS
  • Laser diode pigtails
  • Biomedical probes
  • Couplers
