Abstract
An optical fiber distribution module having a connection board, optical connector adaptors and a storage section is provided. An array of the optical connector adaptors forms the connection board, where the optical connectors connect in-use optical fibers. The storage section, located in a separate section of the module, stores optical fibers which are not-in use. The optical fiber distribution module also includes a plurality of cord sorting boards having a plurality of fiber cord passageways. The fiber cord passageways are configured to accommodate and retain at least one optical fiber such that the optical fiber is arranged between the connection board and the storage section. In addition, both the in-use and not-in use optical fibers insert into the fiber cord passageway. The in-use optical fibers connect to the optical connector adaptors and the not-in use optical fibers are stored in the storage section as the in-use optical fibers and the not-in use optical fibers are inserted within the fiber cord passageways.
