PURPOSE:To make a change into a different branching state by inserting optical connectors of an optical fiber core which has the optical connectors fitted to both ends between specific adapters in a box body into the adapters, and performing branch wiring. CONSTITUTION:An optical branch and connection box 1 has the rectangular prismatic box body 2 and >=3 cylindrical adapters 4 penetrates a specific surface of the box body 3 and are supported. Branch wiring is performed between specific adapters 4 in the box body 2 by inserting respective optical connectors 5 of optical fiber cores 5 having the optical connectors 5 fitted to both ends are inserted into the adapters 4. This optical branch connection box 1 makes an external connection inserting an optical connector 8 atop an optical cable 7 into a specific adapter 4 outside and connected to the opposite optical connector 5. If a different branch connection needs to be made in this state, the optical connector 5 of an optical fiber core 6 in the box body 2 is extracted from the adapter 4 and inserted into an adapter to be branch-connected, thereby entering a new branch connection state. Consequently, a change into a new branch connection state is easily made.
