CLOSURE FOR OPTICAL CABLE CONNECTION

PROBLEM TO BE SOLVED: To improve the use efficiency of coated optical fibers of an optical cable, to not only reserve a work space for fiber cord separation but also protect the coated optical fibers separated into fiber cords, to effectively utilize the optical cable, to exert no effect on the other coated optical fibers when taking out an arbitrary coated optical fiber, to deal with lower part extension and overhead loop wiring of coated optical fibers, and to simplify handling to be able to return a coated optical fiber branched once to a main line. SOLUTION: With respect to a coated optical fiber connection closure 1, a tray 10 for drop coated optical fibers 10 obtained by vertically dividing and laminating a lower layer tray 2 and an upper layer tray 3 is arranged so as to be freely inserted to and removed from an insertion rack of a tray storage case 4, and the lower layer tray 2 and the upper layer tray 3 are provided with a plurality of interior trays 21, 22, and 23and a plurality of interior trays 31, 32, and 33respectively, and each tray is provided with a coated optical fiber leading-in/out part, a connector storage part for storing a connector which connects coated optical fibers from the coated optical fiber leading-in/out part, a splitter storage part, and a coated optical fiber excess part storage part for winding and storing excess parts of the coated optical fibers.
