<p>An optical fiber distribution module achieves high density of connections on one board, yet prevents cord tangling created by repeated connection/disconnection of cords. The module has a connection board (102) with an array of optical connector adaptors (108) for connecting in-use optical fiber cords (104), and a storage section (103) for storing not-in use optical fiber cords (104), where a plurality of cord sorting boards (107) having a plurality of fiber cord passageways for accommodating and retaining at least one optical fiber cord (104) is arranged between the connection board and the storage section. This design of the board enables to organize groups of cords into in-use cords and not-in-use cords. The load on the cords are supported properly so that fiber tangling ane fiber distortion are prevented. Therefore, high density optical fiber can be achieved without introducing signal distortions. <IMAGE></p>
