Abstract
A GGP fiber is provided which resists strength degradation upon exposure to high temperature/high humidity environments. The fiber comprises a polymeric coating, or P-coat, which is cured with a photoinitiator such as an iodonium methide salt which does not hydrolyze to release HF or fluoride ion.
Claims19
An optical fiber, comprising:
- a glass core;
- a glass cladding;
- and
- a polymeric coating, comprising a photoinitiator that does not hydrolyze to release HF or fluoride ion.
1 more element
An optical fiber element, comprising:
- an optical fiber having a numerical aperture ranging from 0.08 to 0.34;
- and
- a protective coating affixed to the outer surface of said optical fiber, said protective coating having a Shore D hardness value of at least 65;
- wherein said protective coating comprises a photoinitiator that does not hydrolyze to release HF or fluoride.
1 more element
An optical fiber, comprising:
- a glass core;
- a glass cladding, disposed about said core;
- and
- a polymeric coating disposed on said cladding, said coating comprising a photoinitiator having a non-hydrolyzable anion.
