Abstract

Fiber optic connectors and other structures that can be easily and quickly prepared by the craft for termination and/or connectorization in the field are disclosed. More specifically, the fiber optic connectors and other structures disclosed are intended for use with glass optical fibers having a large core. In one embodiment, the fiber optic connector includes a ferrule having a bore sized to receive an optical fiber and a buffer layer at a front end face of the ferrule. Methods of making the fiber optic connectors and other structures are also disclosed. The methods disclosed allow “rough cutting” of the optical fibers with a buffer layer thereon by the craft.
