<p><P>PROBLEM TO BE SOLVED: To apply no stress to an optical fiber even if a tube for a loose tube coated optical fiber is extended or contracted due to temperature change or the like. <P>SOLUTION: In a sheet 11 for the optical fiber, the optical fiber 2 wired in sheets 4 is loosely covered with the tube 5 as far as the interior of each of sheet end edges and the tube 5 is drawn out to outside the sheet to serve for the single-core loose tube coated optical fiber 6. Where, the interior portion of the sheets in the tube 5 is covered with a cylindrical member 8 made of a resin, for example. As a result, a structure not restricting movement in the length direction of the tube is formed thanks to the upper and lower sheets 4. For example, when an optical connector 7 is installed on the extremity of the loose tube coated optical fiber 6, tube extension or contraction is absorbed in a manner that the interior of each of the sheets is slid in the length direction of the tube even if the tube 5 is extended or contracted due to the temperature change or the like. As a result, stress applied to the optical fiber 2 is prevented. <P>COPYRIGHT: (C)2003,JPO</p> |
