摘要： A simple and effective all-optical system, producing a multilevel coded optical signal based on the M-ASK technology and by the minimized equipment. The novel all-optical modulation technique for optical M-ASK generation is based on nonlinear interaction between optical signals, say between N 2-ASK modulated pump signals having extinction ratio ER1 and a single 2-ASK modulated optical probe signal having extinction ratio ER2. According to the invention, a 4-ASK optical signal can be obtained using just a single binary modulated pump optical signal and a single binary modulated probe optical signal.

摘要： A method and system are provided for improving bandwidth efficiency in an optical network by dynamically utilizing unused bandwidth located around preliminarily allocated optical channels. The method comprising monitoring actual bandwidth of the preliminarily allocated optical channels incoming to a node of the optical network, reporting the monitoring results to the controller of that node and further to a network controller, receiving at that node recommendations generated by the network controller, adjusting bandwidth of one or more of the allocated optical channels thereby releasing spare bandwidth for inserting one or more additional optical channels thereat.
