Abstract: A fiber optic encryption method is provided. The method includes transmitting an initial security key to a laser receiver apparatus over an out of band (OOB) signaling channel of a plurality of channels of a laser transmitter apparatus. The OOB signaling channel is secured based on the initial security key resulting in a secure OOB signaling channel. A secure bundle is generated. The secure bundle includes the secure OOB signaling channel and a group of channels and associated transmission frequencies. Data is transmitted via the secure bundle and it is determined if any channels do not transmit the data.

Abstract: 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 laser device 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 pulse at the receiver. The receiver determines if the first light pulse is visible at the receiver.
