| 摘要 |
The present invention relates to an optical cable used for a quarter communications network of a passive optical network (PON). User work convenience is increased and a diameter of the optical cable is minimized. The optical cable comprises: a center line; a first optical unit layer prepared around the center line, including a plurality of optical units; a second optical unit layer prepared around the first optical unit layer, including a plurality of optical units; and an outside sheath layer enclosing a circumference of the second optical unit layer. |
