2. Fiber-optic communication - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_communication

   Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of infrared or visible light through an optical fiber. [ 1][ 2] The light is a form of carrier wave that is modulated to carry information. [ 3] Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity ...

   At the top right corner is a monocular for assisting the alignment of the two heads. Free-space optical communication ( FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar.

4. Transceiver - Wikipedia
