Loop Extender

Device in the CO (Central Office) that supplies augmented voltage out to subscribers who are at considerable distances. It provides satisfactory signaling and speech for such subscribers. More specifically, an ADSL (Asymmetric Digital Subscriber Line) loop extender increases the channel capacity of a DSL connection from the CO to the subscriber. ADSL repeaters are aggressively deployed by rural telephone companies trying to reach farms and small towns in areas where it is impractical to place the DSLAM (DSL Access Multiplexers) closer. The typical distance improvement with a loop extender is shown in the diagram below, with rate in Megabits per second and distance in thousands of feet. In future WotD's we will explore in more detail DSL (and ADSL) along with the market for these services.
