Abstract

An optical network comprises a fiber distribution cable and a terminal assembly. The terminal assembly receives a plurality of optical fibers from the fiber distribution cable and distributes one or more individual fibers to one or more single fiber bare-fiber holders that hold and protect each single fiber prepared and configured for splicing via an individual splicing element. The splicing element includes an alignment mechanism having a base plate and a clamp plate. At least one of the base plate and clamp plate is formed from a silica material and at least one of the base plate and clamp plate includes an alignment groove or channel configured to receive the first and second optical fibers in an end-to-end manner. The splice element also comprises an optical adhesive disposed in at least a portion of the alignment groove, wherein the optical adhesive is curable via actinic radiation.
