Abstract

An optical distribution box for transmitting a signal generated by the signal generator to the communication device is disclosed. In the optical distribution box, since a tray for inserting and supporting the optical cable is installed in the housing, the volume of the entire stacked housing is reduced when the housing is stacked and mounted in the rack. Therefore, more housings can be mounted in the same size rack, thereby reducing the cost. In addition, since the jig having a bending part is provided on the front surface of the housing, the adapter is inserted into and coupled to the bending part of the jig so that the adapter faces the side of the housing. Therefore, since the optical cable connected to the front end of the adapter is gently bent toward the rack side, the loss of the transmission signal is minimized. In addition, since the extra optical cable can be wound and stored on the outer circumferential surface of the bracket for supporting the tray, the optical cable is not stored in the state of being drooped out of the housing. Therefore, it is aesthetically beautiful.

Description
