BANDWIDTH THROTTLING

A bandwidth throttling method is provided. The method includes receiving by a receiver from a QD Vcel cannon, a plurality of multi-frequency light pulses via a plurality of channels. The receiver determines that the plurality of multi-frequency light pulses comprises an out of band (OOB) signal transmitted over a first channel of the plurality of channels. The receiver receives from a first laserdevice of the QD Vcel cannon, a first light pulse of the plurality of multi- frequency light pulses. The first light pulse includes a first frequency for testing a visibility of the first light pulseat the receiver. The receiver determines if the first light pulse is visible at the receiver. 提供种带宽限制的方法。该方法包括由接收机通过多个信道从QD Vcel加农炮接收多个多频光脉冲。所述接收机确定所述多个多频光脉冲包括通过所述多个信道中的第信道发送的带外(OOB)信号。所述接收机设备从所述QD Vcel加农炮的第激光器设备接收多个多频光脉冲中的第光脉冲。所述第光脉冲包括第频率，用于在所述接收机处测试所述第光脉冲的可见性。所述接收机确定所述第光脉冲在所述接收机处是否可见。
