drop 1. The portion of a local loop that extends from a distribution cable terminal to a customer’s building. A drop, or drop wire, generally is in the form of a cable containing one to five twisted pairs, or perhaps one or two optical fibers. The term refers to the fact that the small cable often drops from a larger aerial cable suspended above the ground from poles. See also cable and local loop. 2. The portion of an inside wire and cable system that drops from a false ceiling, also known as drop ceiling, perhaps connecting to a pre-wired cubicle or electrical pole, rather than directly to an electrically powered device. |
