Abstract
An optical fiber [,] having protective coating materials [,], which surround an elongated strand of glass [,], is designed for improved strippability. Preferably, the optical fiber includes two layers (primary and secondary) of radiation-cured polymeric materials surrounding the glass fiber. The primary layer has an equilibrium (in-situ) modulus that resides within the range 120 to 500 psi. Additionally, the primary coating has a pull-out force (adhesion) that is less than 1.2 pounds per centimeter of length (lb/cm), and preferably resides within the range 0.5 to 1.0 lb/cm. It has been found that by increasing the equilibrium modulus, delamination resistance is increased. This has allowed designers to decrease pull-out force while maintaining a suitable delamination resistance. As a result, coating materials can now be stripped away from a glass fiber with little or no residue. This is particularly important in situations where a group of such fibers are bound together in an array [,] by a matrix bonding material [
