DeSolite® coatings

Our DeSolite® optical fiber coatings boost fiber microbending performance at the fastest processing speeds - ensuring the best economy of high-speed production and superior fiber attenuation performance. 

In addition to improved microbending performance, DeSolite® optical fiber coatings deliver high reliability in temperature extremes, as well as offering:

Reduced volatility ✓
Faster cure speed ✓
Advanced mechanical properties  ✓

Bufferlite® coatings

Our Bufferlite® products enable you to upjacket optical fiber to 500um and 900um via fast, one-step processing on a slightly modified UV coloring line. These materials offer you excellent strip performance allowing for reduced termination times.

Cablelite® inks and matrix

Our Cablelite® inks and matrix are optimized for loose tube and ribbon designs. They are fast curing; display robust processing at various line speeds with consistent cure; and methyl ethyl ketone (MEK) resistance for all 12 colors.

You can use Cablelite® materials for various ribbon designs including subunit ribbon designs; they have very low water sensitivity - and excellent low temperature performance.
