An apparatus for deployment in an outdoor environment for extending the electrical communication distance of digital data signals includes electrical isolation means for various electromagnetic effects and a high speed pulse reshaper and repeater. The isolation means includes low capacitance electric pulse suppression means so that maximum signal distance can be achieved without loss of usable pulse shape and isolation transformers on differential signal pairs that retain magnetization at elevated temperatures so that signals are not blocked. As a further feature, extended logic is included whereby the type of signals can be distinguished, thus allowing the apparatus to be daisy-chained with like apparatus or used between a termination and a line.
