A USB-C connector for a fiber optic cable has a two-section dongle form. The small plug section has a USB-C plug head and an optical transceiver and control circuitry, but no other signal processing functions. The second section includes a fiber connector and a signal processing chipset, but no optical transceiver. The two sections are connected together by a short hybrid cable containing both optical fibers and electrical wires. The optical fibers connect the optical transceiver to the fiber connector. A subset of electrical wires connect the control circuitry to the chipset, and another subset of electrical wires connect the chipset to a second subset of pins of the plug head. A first subset of pins of the plug head are connected directly to the control circuitry for optical-electrical signal conversion. Two such USB-C connectors connected to the ends of a long all-fiber cable form a USB-C extender.
