Abstract :
The present state of optical coherent communication technologies, covering optical heterodyne/homodyne detection and optical frequency division multiplexing (optimal FDM), is discussed. Included is a description of the development history of coherent lightwave communication technology followed by a discussion of heterodyne detection for future long-haul high-speed systems. A description of optical coherent transmission systems using heterodyne/homodyne detection is presented along with a review of optical FDM technology and its applications. Future trends are examined.<>
