A current mode coupler includes a unitary casing, a stub cable connector, a circuit board, a magnetic structure, a wire core holder, an enclosing lid and an E-core situated in a cavity in the unitary casing and an I-core affixed to the enclosing lid. When the enclosing lid is in a closed position, the E-core and the I-core contact, forming a transformer. When electrical current is present in a data bus that is situated within the E-core/I-core arrangement, the coupler magnetically couples the current mode doublets on the data bus to the circuitry enclosed in the unitary casing. The current mode doublets sensed on the data bus is then converted to voltage mode doublets and transmitted to the stub interface. The current mode coupler also receives voltage mode doublets through the stub interface, converts the voltage mode doublets to current mode doublets, and transmits the current mode doublets via the E-core/I-core arrangement.
