A system that facilitates high-speed data transfer between integrated circuit chips. The system contains a first integrated circuit chip, which includes a capacitive receiver and an electrical-to-optical transceiver. The capacitive receiver receives a capacitively coupled voltage signal transmitted from a corresponding capacitive transmitter located on a second integrated circuit chip and converts the capacitively coupled voltage signal into an electrical signal. The electrical-to-optical transceiver converts the electrical signal to an optical signal and transmits the optical signal to an optical device through optical coupling.
