Abstract

Messenger wires are easily separated from optical elements and termination-fixed. Optical elements to be dropped can be recognized, cut, and taken out without influencing the other optical elements. An optical element assembly cable comprises optical elements each composed of an optical fiber core, a tension member, and a cover covering the optical fiber core and the tension member and a messenger wire supporting the optical elements. Predetermined optical elements taken out in any position are connected to a drop optical cable. An assembly of optical elements and the messenger wire are bundled with a binding member. The optical elements may be twisted or bundled.
