Overview

The BT100 is a three or four output, two-way capable amplifier used in Cable Access Television (CATV) distribution systems. All models are high gain, three-stage hybrid amplifiers designed to drive both a cascade and a local distribution system. The BT100 is powered by the 60/90 VAC cable supply and can be configured to pass this power to additional amplifiers and line extenders. Installation of the return path enables two-way signal flow.

The standard model BT100 includes an amplifier electronics module with an integrated power supply, which is furnished complete in the model BT*-100*/15 housing, as shown in Figure 2-1. You may also purchase the electronics module only with no housing.
