Abstract: The present invention relates to an electrical connector for telecommunications applications, including a circuit board and first and second electrical contacts, extending from the circuit board along first and second paths, respectively, the second path crossing the first path. A third electrical contact extends from the circuit board along a third path, and a fourth electrical contact extends from the circuit board along a fourth path, the fourth path crossing the third path. At least four electrical terminals extend from the circuit board and at least four electrically conductive traces on the circuit board electrically couple each of the first, second, third and fourth electrical contacts to a respective electrical terminal.

Abstract: An adapter for a data transmission or communication system, has a body with a longitudinal axis. Longitudinal ends of the body define coaxial openings. One plug is receivable in one opening. Another plug is receivable in the other opening in at least two positions angularly offset relative to one another about the longitudinal axis of the body. Placement of the other plug in the different positions results in a polarity reversal of the system.
