A first electronic device optically communicates with a second electronic device. Each of the devices includes one or more optical transmitters, one or more optical receivers, and one or more lenses where each of the lenses includes at least a first and a second optical path that are optically isolated from each other. When the first electronic device transmits data to the second electronic device, an optical transmitter of the first electronic device transmits to an optical receiver of the second electronic device via the first optical paths of the lenses of the first and second electronic devices. Similarly, when the first electronic device receives data from the second electronic device, an optical receiver of the first electronic device receives from an optical transmitter of the second electronic device via the second optical paths of the lenses of the first and second electronic devices.
