OPTICAL SWITCHING SYSTEM |
摘要 |
When the subscribers are connected with the switching system by the optical fibers, in order to realize the signal exchange without converting the optical signals sent by the optical fibers into the electric signal, the optical switching system is constituted by: an optical time division multiplexer for time division multiplexing the optical signals which were sent by a plurality of fiber optic cables corresponding to a plurality of subscribers; an optical time switch for changing the time arrangement of the output signals of the optical time division multiplexer; and an optical time division demultiplexer for distributing the time sequential signal of the output signals of the optical time switch to the optical fibers of a plurality of subscriber lines.
