Abstract: The new broadcast center of Fuji Television Network Inc. requires a large capacity and flexible routing network for video/audio signals. It has been decided to employ the newly developed wavelength-division and time-division hybrid multiplexed (WD/TD) optical network for video/audio signal distribution/transmission in the new facilities, in order to extend possibilities in the coming multimedia era. A prototype WD/TD optical network has been developed to examine basic operation and preliminary reliability issues. The prototype has been designed to distribute/transmit 240 digital NTSC video signals, employing a newly developed flat gain optical amplifier and a 2.29 Gbit/sec time-division multiplexer/selector. The prototype has been under field trials at the master control room of Fuji Television Network Inc. and has shown successful operation.
