"affordable, low-power transceivers transmit and receive laser signals... transceiver based on optical SoC output higher power into FSO system... does not need amplify signal as much before transmitting... improvin noise profile... transmission speeds 100 Gbit/s... deployed quickly... more bandwidth capacity, security features, and less power consumption than traditional point-to-point microwave links. And since it does not use the RF spectrum, it is unnecessary to secure spectrum licenses"
