<p><P>PROBLEM TO BE SOLVED: To solve the problem that the length of an optical fiber having connectors that is led to the terminal of an optical fiber cable (cord cable) at a transmission apparatus that is pulled into a optical wiring board is not nearly uniformly arranged although it is not uniform conventionally corresponding to a difference in the position of an optical connector in the optical wiring board, and that a technique for securing working efficiency in switching connection or the like is requested. <P>SOLUTION: In an optical wiring board 10, a hooking member 61 for absorbing a difference in the wiring length of an optical fiber 12a by hooking the optical fiber 12a (optical fiber cord) introduced from an introduction section 15 is arranged and installed in multiple stages up and down at a rack body 17 corresponding to up/down multiple-stage terminal units 13, and further a surplus length absorption section 62 for performing the curving treatment of a surplus length 12c in the optical fiber 12a is provided between each hooking member 61 and a wiring stage 31. <P>COPYRIGHT: (C)2003,JPO</p> |
