fibre optics can be used to transmit light as a source, the simplest example would be an endoscope, where light is generated at one side of the fibre optic, transferred to the other, then reflected and transmitted back as a signal.
Transfer over a fiber optic will however reduce the power of a signal, especially when transferring over large distances. this isn't a problem with signals as actual data is conserved and power can be boosted at regular intervals.
the only time a fibre optic is used to transmit "raw" light is when the heat associated with generating light is detrimental, for example in a gas pipe or a human body.
What else can I help you with?
What is the basic principle of fiber sensor?
A fiber optic sensor in general consists of a light source. The light source is coupled to an optical fiber. A light source which receives signal-carrying light beam on it emerges from the fiber. The signal from detector is processed electrically for getting information.
What property of light is used in optical fibers?
a signal is beamed as a light through the fiber optics and when they are relayed to the other side a computer decodes the signal that's also how fiber optic TVs work
What US autos use fiber optics and where?
general motors used to light door lock cylinders ,ignition cylinders, fender mounted turn signal indicators
What is a broadband service that transfer data at the speed of light?
fiber optic
Which travels faster an digital video signal or audio signal?
Depends. If they're all encoded for transfer by electronic means(radio, fiber, wire) they'll all travel at the same speed. But if you by audio signal mean sound in the air, then sound travels at about 700 miles an hour. A digital signal - electrical/optical - travels at the speed of light (186,282 miles per second) down a fiber network.
How a scratch outside of an optical fiber might cause problems?
Fiber optics, using optical fiber, are specially designed to implement total internal reflection. A signal passed from one end of the fiber to the other end of the fiber is a single beam of light that repeatedly bounces off the edges of the fiber until it reaches it's destination. By scratching the outside of an optical fiber, this property can be disrupted causing the signal to be lost.
Why do signals in the fiber optics cables travel at the speed of light?
fiber optics transfer data at the speed of light because that's exactly what is transmitted through them... light. fiber optic cables are thin pieces of glass that transmit light pulses
What is the meaning of Infer-red transfer?
Infa-red file transfer is the use of infa-red light to transfer files to a reciever of infa-red light. (example: A wii remote uses infa-red light to send a signal, and a wii reciever receives the signal)
Angle of obliqueness in optical fiber?
The angle of obliqueness in optical fiber refers to the angle at which light enters the core of the fiber relative to the normal (perpendicular) to the fiber's surface. This angle is crucial for total internal reflection, which allows light to be guided along the fiber. If the angle exceeds the critical angle for the core-cladding interface, light will refract out of the fiber instead of being guided, leading to signal loss. Maintaining the appropriate angle of obliqueness is essential for optimal fiber performance and signal integrity.
What is meant by atenuation in fiber optics?
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
What is the meaning of Infer-red file transfer?
Infa-red file transfer is the use of infa-red light to transfer files to a reciever of infa-red light. (example: A wii remote uses infa-red light to send a signal, and a wii reciever receives the signal)
What communication medium uses pulses of light?
Fiber Optics uses light to signal on and off with each pulse, copper cables use power frequency, high and low to signal on and off.
