摘要：
Coherent optic switching provides an effective solution for broadband switching.
Advantageously, the control information should also be transmitted optically.
A broadband multiport coherent optic data switch comprises a passive optic combiner/splitter, a plurality of port units and a switch control unit connected thereto, each port unit having a coherent optic source tuned to a respective optic frequency, the output of each source carrying thereon control information, including control information received from the control unit, together with switched data, the outputs of the sources being combined and distributed to all of the plurality of port units.
