The 614T and 614R are a small and lightweight, detachable optical transmitter and receiver pair. They transmit uncompressed DVI resolutions of up to 1920x1200 at 60Hz using one multimode fiber optic cable with SC connectors. The 614T converts the DVI signal to an optical signal that it transmits to the 614R. The 614R decodes the optical signals back to a DVI signal.
