PURPOSE: A communication box structure is provided to integrate communication components into an attachment board while constructing a superhighway communication network, in order to receive the components in a body, and to install cooling fans and cooling vents to exhaust internal heat, thereby enabling stable communication. CONSTITUTION: A body(10) forms cooling vents(10e) having cooling fans and many vent holes(10f) on both sides, to exhaust internal heat, and installs doors(30,40) for being bidirectionally opened/closed. An optical adapter attachment board is installed in an attachment board, and is connected to a switching hub. An optical tray receives a remaining optical core of an optical cable inserted by being attached to a side of the optical adapter attachment board, and takes in and out the optical core when necessary.
