摘要:
A telecommunication apparatus includes a shelf and a plurality of packages. Optical fibers are laid around a rear surface of the shelf in a direction of Z2. Each of the optical fibers is dragged in a direction of X1 into a corresponding cartridge from a rear surface thereof. The cartridge is provided near an upper side of the rear surface as an excessive length treating portion. Then the optical fiber is drawn out of an upper surface of the cartridge so as to enter a space formed in the upper shelf from the rear surface thereof. After that, the optical fiber is extended and connected to an optical plug provided on a front portion of the package.
