| 摘要 |
The present invention relates to an optical terminal box which couples a tray to be able to rotate in a main body, which comprises: a first optical adaptor unit coupled to the tray through a first coupling unit; and a second optical adaptor unit stacked on the first optical adaptor unit, and coupled to the tray through a second coupling unit. The first and second coupling units are arranged not to be overlapped. Therefore, one adaptor can be separated from or assembled in the tray while any one from two optical adaptors is installed, thereby increasing user convenience. |
