A unidirectional cable connector that can be operatively connected between a host device and accessory device in the ecosystem of products. The cable includes first and second plug connectors at opposite ends of a wire where the two plug connectors share a common pinout but the insertion plug of the second connector is shortened in length as compared to the insertion plug of the first connector. The shortened plug prevents the second connector from being fully inserted into the host device that includes a standard depth receptacle connector, and thus prevents the second connector from being operatively coupled to the host device. The shortened plug can, however, be operatively connected with an electronic device having a shortened receptacle connector according to embodiments of the disclosure.
