Explanation:

Free-space optical communication (FSOC)is an optical communication technology that uses light to wirelessly transmit data to telecommunication and internet applications. The technology remained outside the commercial applications for long owing to distance, speed, and efficiency related problems.

FSOC links use beams of light to deliver high-speed, high-capacity connectivity over long distances, just like fiber optic cable, but without the cable. And because there’s no cable, this means there’s none of the time, cost, and hassle involved in digging trenches or stringing cable along poles.
FSOC boxes can simply be placed kilometres apart on roofs or towers, with the signal beamed directly between the boxes to easily traverse common obstacles like rivers, roads and railways.
In a first, X Development LLC, a subsidiary of Google's parent company Alphabet Inc, will supply and deploy two thousand cutting-edge Free Space Optical Communication (FSOC) links for Andhra Pradesh (AP) fiber-grid.
One example of the use of this technology can be LAN-to-LAN connections on campuses at Fast Ethernet or Gigabit Ethernet speeds or in a metropolitan area network.
