<P>PROBLEM TO BE SOLVED: To provide a mechanism capable of completely protecting extra length parts of a primary side and a secondary side optical cords in an optical wiring board equipped with a slide type splice unit. <P>SOLUTION: A slide type splice unit 5 is supported on a mount angle 2 in a rack. A primary side wiring duct 8 is laid between a stationary part 6 and a movable part 7 of the splice unit 5, and an extra length part of a primary side optical cord C1 is guided. A secondary side wiring duct 9 guiding the extra length part of a secondary side optical cord C2 is laid between the movable part 7 and the mount angle 2. A duct case 11 is installed on the mount angle 2, and a bent part 9a of the secondary side wiring duct 9 is stored to freely go in and out. The duct case 11 is formed so as to spread toward a slide direction of the splice unit 5. A cable clamp 16 for holding an optical cable exposed from the primary side wiring duct 8 and a fusion connection holder 19 for holding a fusion connection part of the optical cable are provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
