Practical Implementation of an Optical Network in Broadcast Stations

The new broadcast center of Fuji Television Network Inc., which is to be under operation in 1996, is now under construction. The new broadcast center 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. This, to our knowledge, would be the world first implementation of optical networks in broadcast centers. A prototype WD/TD optical network has been developed to examine the basic operation and preliminary reliability issues. The prototype has been designed to distribute/transmit 240 digital NTSC video signals, employing newly developed flat gain optical amplifier, and 2.29Gb/s Time-Division Multiplexer/Selector. The prototype has shown successful operation and is now under field trials at the master control room of Fuji Television Network Inc. Based on the results of the trials, the network in the new broadcast station will be designed and constructed.
