How does information travel in fiber optic cables?

Answer 1

Your question is a bit vauge, but I will try to answer it. A signal is transmitted via an infra-red LED or laser. The on and off pulsing of the light represents 1 and 0 in binary. There are 2 types of fiber, multi-mode and mono-mode. As for what information can be sent that depends on equipment you connect: video, voice, multimedia, remote-control, data (computer network, etc). In most company / office networks you will find Multi-Mode as it is easier and cheaper to install and purchase the parts for. It is limited to about 600-2000 meters. The speed limit is based on the hardware connected to the fiber and the distance, but you can do 10 Gigabits across 300+ M. You only see Mono-Mode (Single-Mode) fiber in the Telecom industry. It is very expensive to purchase, difficult to connect, and the equipment that uses it is also expensive. It can go about 10-60-1000+ KM. I have added some links to look at.

Answer 2

"A fiber optic cable consists of a core, wrapped in cladding, wrapped in buffer coating. Being composed of long, thin strands of pure glass, they function by transmitting light signals over long distances."

Answer 4

Light travels through strands of fiberglass in a fiber optic cable by reflecting off the insides of the fiber strand.

Answer 5

A transmitter sends light down optical fiber

Answer 6

Information travels in fibre optic cables by electric waves that go through the wires :)

Answer 7

Fibre Optics transmit data via refraction. It uses the concepts of Core and cladding.
