A new design for SC and LC connectors allows them to be non-pull-proof to address the specific needs of tight-jacketed cable construction. The SC and LC connectors were originally designed for pull-proof applications and required the buffer to move independently of the fiber jacket. When used with tight-jacketed cable, standard SC and LC connectors could induce a microbend, which causes increased insertion loss or fiber breakage. With the new design, termination allows the jacket and buffer to move together. Products are now available for both singlemode and multimode LC and SC connectors in 1.6- to 2.4-mm-diameter cable.
