Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an optical emission system and an emission method, an optical switching device and a control method. Background technique [0002] With the increasing demand for high-bandwidth services, the demand for switching capacity in switching networks is also increasing. However, traditional electrical switches cannot meet the demand for continuous growth of switching capacity due to technical limitations such as backplanes and energy consumption. Optical switches have attracted more and more attention due to their low energy consumption and large capacity. [0003] At present, the burst mode transmission mechanism is mostly used in optical switching systems to send optical signals, that is, there are intervals between data packets carried in optical signals, so burst signals are generated, such as burst signals. Figure 1A Shown. Because the amplitude difference between burst sig...
