てなる防水型光フアイバケーブル。 A single or multiple optical fiber core is stored in the optical fiber core storage groove of the spacer in the tensile strength core, and the outer periphery is wrapped with a water-absorbing swelling tape as the lower layer and a jewelery-blocking tape that does not transmit the jewelery as the upper layer. A plurality of the optical fiber units are twisted around a central tensile strength member, and the gap formed between these optical fiber units, the central strength member, and the entire presser-wrapped tape is filled with a wire. A waterproof optical fiber cable filled with water-preventing jewelry.
