Abstract:
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 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; andC) a Tube Tg, of from about −25 C. to about −55 C. ; wherein the cured Secondary Coating on the optical fiber has the following properties after initial cure and after one month aging at 85 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.
