Patent ID: 8406596

Claim:
An optical fiber comprising: a glass fiber; and three or more coatings that encapsulate the glass fiber, where the three or more coatings comprise a primary coating in contact with said glass fiber, an intermediate coating that surrounds the primary coating, and an outer coating that surrounds the intermediate coating; wherein the primary coating comprises a Young's modulus of about 0.025 to about 3 MPa and a glass transition temperature (T g ) of about −100° C. to about −25° C., and the intermediate coating comprises one or both of a Young's modulus that is substantially the same as, or lower than, the Young's modulus of the primary coating, and a T g that is substantially the same as, or lower than, the T g of the primary coating; and wherein the outer coating of the optical fiber has a diameter that is less than about 300 μm.
