ELECTRICAL DEVICE FOR MULTIPLE-SIGNAL INJECTION ONTO MULTIPLE-CONDUCTOR COMMUNICATIONS MEDIUM

摘要

An electrical device includes signal ports, transformers, and a differential mode device. The transformers are in communication with the signal ports, respectively. The transformers are configured to receive input signals, respectively, from the signal ports. Each transformer is configured to inject the respective input signal onto a pair of output lines of the transformer. The differential mode device is connected to a first output line of the pair of output lines of a first transformer exclusive of connection to a second output line of the first transformer. The differential mode device is configured to inject a signal from the first output line onto the pair of output lines of a second transformer. Signals from the pair of output lines of the second transformer are injected onto a pair of conductors, respectively, of a communications medium.
