<p><P>PROBLEM TO BE SOLVED: To obtain a multi-core optical fiber branch structure capable of stably fixing a branching section while making the branching section compact. <P>SOLUTION: When the multi-core optical fiber 1 is branched into two or more, the branching section is caught between two upper and lower soft resin sheets 14 and 15 together with end sections of protection tubes 3 coated on branched optical fibers. Such a short width is given to the sheets 14 and 16 that the sheets are not stuck to each other, and at least an entire sheet part is stored and fixed in a thermo-shrinkable tube 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
