In optical communications, zip-cord is a two-fiber cable consisting essentially of two single-fiber cables having their jackets conjoined by a strip of jacket material. The name is borrowed from electrical terminology referring to lamp cord. As with lamp cord, optical zip-cord may be easily furcated by slitting or tearing the two jackets apart, permitting the installation of optical connectors. Zip-cord cables include both loose-buffer and tight-buffer designs.
