An apparatus and method for splitting or otherwise separating and routing optical fibers are provided in which a splitter housing having first and second separable halves is mounted upon a plurality of optical fibers without having to cut all of the optical fibers. The splitter housing generally includes an inline portion and a branch portion. The inline portion defines an input port at one end for receiving a plurality of optical fibers and a primary output port at the opposed end through which at least one optical fiber exits. The branch portion extends outwardly from the inline portion at one end and defines a secondary output port at the opposed end. The branch portion is in communication with the inline portion such that at least one optical fiber that enters through the input port can be separated from the remainder of the optical fibers and routed through the branch portion.
