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:
