Why fiber coatings matter

Optical fiber coatings are one of the critical, if least well-known, components of high-speed fiber networks. There would be no high-speed Internet today without the high-performance coating systems that DSM has been engineering for the past 40 years.

Fiber coatings have two very important functions:

  • Allow fiber optic wire and cable makers to physically work with very delicate strands of glass fiber, which are about the size of a human hair.
  • Allow fiber to carry signal at a tremendous rate of speed with as little interruption or distortion as possible.

Coatings not only protect fiber from outside environmental stresses like temperature extremes, but on the inside coatings ensure the reliability of the signal being carried.

When you consider costly fiber networks that have to last 20-30 years in the field, while handling greater and greater through-put demand, you quickly realize that coating quality is key.
