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

DETAILED DESCRIPTION It is an object of the present invention to provide interchangeable talk sets that can communicate with full duplex capability over a single optical fiber.
It is a further object of the present invention to provide a method and apparatus that can communicate on an optical fiber at long ranges and is unaffected by reflections produced on the optical fiber.
