No. Light is transmitted through optical fibers.
Copper wires and satellite transmission.
Good optical fiber is made of glass, but inexpensive fiber is sometimes made of plastic.
Study the optical transmission property of glass, to learn more. also: http://en.wikipedia.org/wiki/Optical_fiber You might wish to refine the question to differentiate between optical bandwidth and data bandwidth. If a laser can be modulated and the beam directed through an optical fiber, then the data or the analog bandwidth is about equal to the modulation bandwidth capability of the laser in Hz per second.
1. Fusion splices: Use an arc to melt and connect two fibers. 2. Connectorised splices: Use various types of connectors like BNC, ST, etc. These can either be straight- or diagonal-cut fibers. 3. Epoxy splices: Here fibers are joined with the help of refractive index matching glue and guiding sleeves or jackets.
Partition Noise, which occurs in vacuum tubes, optical fibers etc.

Typically, light in the form of laser beams is used to carry information through optical fibers. The laser light pulses encode data that is transmitted through the fibers in the form of light signals.
Laser light is transmitted through specialized optical components such as lenses, mirrors, and fibers. These components are designed to control and guide the direction of the laser beam while maintaining its intensity and coherence. Lasers can also be transmitted wirelessly through the air in free-space communication systems.
Light travels in an endoscope through a series of optical fibers that transmit the light from the source at one end to the tip of the endoscope. These fibers guide the light through the instrument, allowing it to illuminate the target area inside the body. The reflected light is then transmitted back through the fibers to the eyepiece or camera for viewing by the user.
Fiber optics does not transmit sound. The long tiny fibers are long narrow strands of glass or a glass-like material generally referred to as optical fibers. Light travels inside these strands with little loss. Modulating the light makes the light into a signal and so the light can carry information. One common use of optical fibers to transmit information is the use to communicate phone calls, so sound is convered to a light signal and transmitted through optical fibers and at the other end it can be converted back into sound. Optical fibers do not transmit sound but transmit light that contains the information abut the sound. The phase "concentrated light" does not really apply to this process in an obvious way because "concentrated" is a term with meaning only in a comparative sense. Light is transmitted through optical fibers and carries digital information of all sorts.

Optical fibers work by transmitting light signals through total internal reflection. This means that when light enters the fiber at a certain angle, it reflects off the walls of the fiber and continues to travel through it without escaping. This allows the light signals to be transmitted over long distances without losing much of their intensity or quality.
The principle of optical fiber is based on total internal reflection, where light is confined and transmitted along the core due to differences in refractive index. Light propagates through optical fibers by bouncing off the core-cladding interface, allowing for high-speed and long-distance transmission of data through the fiber. This principle enables optical fibers to efficiently transmit light signals without significant loss over long distances, making them ideal for telecommunications and data transmission.
A message is transmitted through a glass fiber using light signals. A laser or LED light source is used to encode the message into light pulses, which travel through the glass fiber via total internal reflection. The light pulses are detected and decoded at the receiving end to recover the original message.
isn't that what optical light is? like you know on certain fake Christmas trees ,, they have those lights in them that change colors; not tree lights but optical lights?
No.The idea of optic fibers is to transfer light as in pulses of information.We use optic fibers during surgery too, and these fibers can carry high energy beams.Thought of mind:It is possible to convert electricity into light, transmit it through the cable and then use a solar-panel at other end to convert back to electricity again.The loss would most likely be great. The energy would need to be "packed" together in a tiny lazer beam. This beam would possibly burn through your Solar-panel at the other end.
The so-called "total internal reflection".
