Abstract
A fiber recoating process and a recoated optical fiber formed by the process that comprises the steps of providing an optical fiber having a coating and cutting a first cut boundary spaced from a secondary cut boundary to mark an internal section of the coating that has opposing sides. Removal of the coating from at least one of the opposing sides provides a pared intervening layer and further forms a first transition region opposite a second transition region. Each of the first transition region and the second transition region has a substantially wedge-shaped contour. Solvent treatment of the pared intervening layer weakens the bond between the coating and the optical fiber between the first cut boundary and the second cut boundary before displacing the coating from the optical fiber to provide the stripped optical fiber. The stripped optical fiber includes a section of optical fiber, the first transition region and the second transition region. After applying recoating material, the stripped optical fiber becomes the recoated optical fiber in which the recoating material covers the section of optical fiber, the first transition region and the second transition region.
