Abstract
A length of optical fiber has a core, a cladding layer surrounding the core and a coating layer applied over the cladding layer along the fiber for protecting the fiber. The coating layer is applied so that gaps of a certain width are defined intermittently in the coating layer over the length of fiber. The gaps in the coating layer have a depth D that is set to expose the cladding layer enough within the gaps so that the exposed cladding layer and the surrounded core can be fusion spliced or terminated with minimal if any required stripping of the coating layer off of the cladding layer.
