Abstract
Summary form only given. The complete setup, shown as a block diagram in demonstrates the optical transparent switching of l4O-Mbit/s line-coded video signals, which are modulated on optical carriers. Each fiber input guides two 12.5-GHz-spaced optical carriers to the cross connect, where the TV signals are switched to two output fiber with two optical carriers. Each output is guided to a heterodyne receiver. After decoding, the pictures are visible on two monitors. All channels can be switched independently over the cross connect with a bit error rate of better than 10-9.
