Abstract: The apparatus of the present invention includes an audio encoder (19) and decoder (21), a memory (27), a transmitter (38) and a receiver (40) that are optically coupled to an optical fiber (17), and a controller (23). The audio encoder (19) produces samples of an audio input at a regular rate. The samples are accumulated in the memory (27). When enough samples have been accumulated, the transmitter (38) begins to transmit the accumulated samples over the optical fiber (17) in a burst. After transmitting, the apparatus pauses long enough to allow reflections on the optical fiber (17) to attenuate to an undetectable level. Then, the receiver (40) is actuated to receive any incoming burst of data, wich are stored in memory (27) until sent to the audio decoder (21).
