Abstract: A method of laying an optical cable in an aerial line which comprises the steps of winding the optical cable measured in a necessary length between laying zones on a reel, mounting optical connectors at both ends of the reel, laying the optical cable by winding at the aerial line by mounting the reel on a winding machine moving on the aerial aline already installed, disposing the optical connectors on the supports at both ends of the laying zone, similarly laying at the adjacent zones of the laying zones, and connecting the optical cables of the adjacent zones on the support. Thus, since the optical cables of the adjacent zones can be connected on the support, the connecting work at the laying site can be extremely simplified. Thus, this method can very simply connect at the laying site by connecting the optical cable of the adjacent zone on the support.
