Abstract
An optical fiber includes a coating comprising a cross-linked network comprising the reaction product of monomers and oligomers and at least one polymer dispersed or interpenetrated in the cross-linked network. The oligomer and polymer components used are at least partially fluorinated. The fiber-coating composition of the invention presents a refractive index that is low while satisfying the conditions for industrial fiber-drawing.
Claims17
An optical fiber including a coating comprising:
- a cross-linked network comprising the reaction product of at least one monomer and at least one oligomer that is at least partially fluorinated;
- and
- at least one polymer that is at least partially fluorinated and that is dispersed or interpenetrated in said network, wherein the at least one oligomer is selected from the group of polyfluoroether (meth)acrylates.
An optical fiber including a coating comprising:
- a cross-linked network comprising the reaction product of at least one monomer and at least one oligomer that is at least partially fluorinated;
- and
- at least one polymer that is at least partially fluorinated and that is dispersed or interpenetrated in said network, wherein the optical fiber presents a numerical aperture greater than or equal to 0.5.
An optical fiber including a coating comprising:
- a cross-linked network comprising the reaction product of at least one monomer and at least one oligomer that is at least partially fluorinated;
- at least one polymer that is at least partially fluorinated and that is dispersed or interpenetrated in said network, wherein the optical fiber has a multimode core.
