特徴とする光フアイバ心線支持用スペーサ。 An inner layer of plastic sheath that adheres to the tensile strength wire and has a rough outer surface is applied around the tensile strength wire, and an outer layer of plastic sheath that has a plurality of spiral grooves in which the optical fiber core is housed is applied by extrusion around the inner layer of plastic sheath that is bonded thereto and has a rough outer surface. The plastic coating inner layer and the plastic coating outer layer are formed by forming a rough outer surface of the plastic coating inner layer and a rough inner layer formed by extruding the plastic coating outer layer thereon and contacting the rough outer surface. between the surface and
A spacer for supporting an optical fiber core, characterized in that the spacer is joined in the length direction and the circumferential direction.
