Polyimide coated singlemode fiber

Polyimide coated
Singlemode
PI SM

In contrast with standard acrylate fiber coatings, the polyimide coating is rated to high temperature and the coating only needs to be very thin.

The high temperature rating makes the fiber ideal for sensing solutions in harsh environments as well as for medical sterilization. The thin diameter makes it attractive for e.g. bundling or embedding.
