Abstract: A cable installation system for use by a cable installer may include a plurality of cable dispensers having different lengths of cable. In particular, each cable dispenser may also have a non-numeric, length-identifying marking associated therewith corresponding to the length of cable. Furthermore, the system may also include a cable dispenser indicator device for use by the installer to determine a distance between first and second locations, such as a cable tap and a subscriber interface. The cable dispenser indicator device may also provide an indication to the installer of the non-numeric, length-identifying marking corresponding to the determined distance so that the cable installer can select the corresponding cable dispenser from the plurality thereof. By way of example, the non-numeric, length-identifying markings may include a series of different colors and/or graphics for respective length ranges.
