The invention provides an optical fiber coated with a Supercoating, wherein the Supercoating comprises at least two layers, wherein the first layer is a Primary Coating that is in contact with the outer surface of the optical fiber and the second layer is a Secondary Coating in contact with the outer surface of the Primary Coating, wherein the cured Primary Coating on the optical fiber has the following properties after initial cure and after one month aging at 85&#xb0; C. and 85% relative humidity: A) a % RAU of from about 84% to about 99%; B) an in-situ modulus of between about 0.15 MPa and about 0.60 MPa; and C) a Tube Tg, of from about &#x2212;25&#xb0; C. to about &#x2212;55&#xb0; C.; wherein the cured Secondary Coating on the optical fiber has the following properties after initial cure and after one month aging at 85&#xb0; C. and 85% relative humidity: A) a % RAU of from about 80% to about 98%;B) an in-situ modulus of between about 0.60 GPa and about 1.90 GPa; andC) a Tube Tg, of from about 50&#xb0; C. to about 80&#xb0; C.

D1381 supercoatings for optical fiber

The present invention relates to a coated optical fiber comprising a glass optical fiber with a single protective coating or a combination of an inner and an outer primary coating applied thereon and optionally with a colored coating subsequently applied thereon wherein the inner primary coating or at least a portion of the single coating is prepared from a radiation curable composition which when cured as a capillary film with a 100W medium pressure mercury lamp has a percentage reacted acrylate unsaturation of at least about 54% after exposure to a dose of about 4.4 mJ/cmor wherein the outer primary coating is prepared from a radiation curable composition which when cured as a capillary film with a 100 W medium pressure mercury lamp has a percentage reacted acrylate unsaturation of at least about 56% after exposure to a dose of about 4.4 mJ/cm. The invention further relates to a radiation curable composition having a high cure speed.

Radiation curable resin composition

The present invention relates to a coated optical fiber comprising a glass optical fiber with a single protective coating or a combination of an inner and an outer primary coating applied thereon and optionally with a colored coating subsequently applied thereon wherein the inner primary coating or at least a portion of the single coating is prepared from a radiation curable composition which when cured as a capillary film with a 100 W medium pressure mercury lamp has a percentage reacted acrylate unsaturation of at least about 54% after exposure to a dose of about 4.4 mJ/cm or wherein the outer primary coating is prepared from a radiation curable composition which when cured as a capillary film with a 100 W medium pressure mercury lamp has a percentage reacted acrylate unsaturation of at least about 56% after exposure to a dose of about 4.4 mJ/cm . The invention further relates to a radiation curable composition having a high cure speed.
