Abstract

There is provided a wall outlet with at least one optical fiber adapter, wherein the wall outlet provides slack storage for an optical fiber generally routed through the wall. The wall outlet comprises a panel that includes at least one optical fiber routing guide adapted to provide slack storage for the optical fiber generally routed though the wall. The panel may be moveably joined to the wall outlet body and the optical fiber routing guide may define a minimum bend radius of less than about one inch. The wall outlet provides improved storage of optical fiber slack that may be utilized when optically connecting an optical fiber to the optical fiber adapter.
