D1381 Supercoatings for optical fiber

The present invention relates to a super-coated with a coating an optical fiber, The super coat comprising two or more layers, the first layer, wherein the optical fiber outer surface and the first coating to contact, and the second layer is a second coating in contact with the outer surface of said first coating, The primary coating is cured on the optical fiber to one month after the initial cure and after aging in a 85 & lt; 0 & gt; C and 85% relative humidity has a characteristic: (A) about 84% to about 99%% RAU, (B) from about 0.15 MPa to about 0.60 MPa in the in-situ modulus, and (C) -25 & lt; 0 & gt; C to about -55 & lt; 0 & gt; C around the tube Tg, The cured secondary coating on the optical fiber has the following properties after 1 month aging, and in the initial cure and after 85 & lt; 0 & gt; C and 85% relative humidity: (A) about 80% to about 98%% RAU, (B) from about 0.60 GPa to about 1.90 GPa in the in-situ modulus, and (C) from about 50 & lt; 0 & gt; C to about 80 & lt; 0 & gt; C of the tube Tg.
