PROBLEM TO BE SOLVED: To move an existing line and to eliminate the entwining of the existing line and an extension line by composing an optical coupler storage tray of an optical coupler storage and fixation tray part which stores an optical coupler and an optical connection part storage and drawer tray part. SOLUTION: An extension optical coupler storage tray 20 has two tray parts which are an optical coupler storage and fixation tray part 21, and an optical connection part drawer tray part 22, and the optical coupler storage and fixation part 21 is a tray in which an optical coupler is installed similarly to an ordinary optical coupler storage tray. The optical connection part drawer tray part 22 is stored in the storage opening part 23 of an optical coupler storage tray main body so that it can be drawn out. The optical connection part drawer tray part 22 is a tray which stores an optical connection part for connection the optical coupler and an optical fiber. Namely, this extension coupler storage tray 20 has both the function of the ordinary optical coupler storage tray and the function of the ordinary optical connection storage tray, and the optical connection part drawer tray part 22 corresponding to the optical connection storage tray is a drawer type that facilitates optical connection operation. |
