An optical fiber distribution apparatus includes a panel extending along a first direction and formed with a first mounting hole and at least two second mounting holes spaced apart from the first mounting hole along the first direction. A plurality of rows of optical fiber connector adapters are arranged in a stack in a direction transverse to the first direction and are inserted into the first mounting hole. At least two multi-fiber push on (MPO) connector adapters are respectively inserted into the at least two second mounting holes.
