Doubler - Telecommunications

A device which doubles the distance of certain types of circuits. HDSL (High-bit Digital Subscriber Line) is a repeaterless means of provisioning a T-1 access circuit over a standard UTP local loop. Signal attenuation issues limit the range, however, to 12,000 ft on 24 guage wire, and 9,000 ft on 26 guage wire.
