Describe how FSO uses infrared to transmit signals.
What will be an ideal response?
FSO uses infrared (IR) light transmission instead of RF. The light technology is similar to that used with a fiber-optic cable system. A fiber-optic cable contains a very thin strand of glass called the core, which is only as thick as a human hair. Instead of transmitting electrical signals, fiber-optic cables use light impulses. A light source, usually created by a laser or light-emitting diodes (LEDs), flashes a light at one end of the cable that is detected at the receiving end.
