A Universal Serial Bus (USB) dongle may include an optical transceiver having a USB inter face for engagement to an electronic device such as a laptop computer or other USB-configured device. The USB dongle may include a converter or buffering, isolation, modulation or amplification circuitry. The USB dongle sends and receives data signals which may be carried upon an optical transmission as generated by an LED light source which in turn is in communication with a host device such as a network processor. The USB dongle may also include operational amplifiers (op-amps) and transistor amplifiers.
