Abstract
The present invention relates to an optical fiber that includes a glass fiber and three or more coatings that encapsulate the glass fiber, where the three or more coatings include a primary coating in contact with said glass fiber, one or more intermediate coatings that surround the primary coating, and a secondary coating that surrounds the intermediate coatings. Both three-coating and four-coating systems are described that afford improve microbend performance.
