What is the source to transmit information in a optical fiber?
Optical fiber is used to carry light ... either visible or else infra-red. So the source you want to use is a stable, reliable source of light, that's small enough to efficiently couple into the tiny window at the end of the fiber, and whose brightness can be changed easily and fast in order to put information onto the light (modulate it). It also helps if the light consists entirely of a single color (wavelength), because different wavelengths travel down the fiber at different speeds, so multiple wavelengths could get spread out and arrive at the far end in a real mess. The best, most widely used source available today is the laser diode.
Optical fiber cables transmit light from one end to the other. The data is encoded into this light beam and travels down the fiber in this light. Obviously you need optical sensors at each end to get the information in and out.
fiber optical wire
The optical fibre is a thin fibre used to conduct light. It can also be used to transmit information as in telephone calls, Internet and cable television.
No. Optical fibers only transmit light.
Optical fibers transmit light, not electrical energy.
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.
Yes, but you have to be careful about the choice of material used to transmit the microwaves so as to avoid resonance.
There are two basic types of optical fiber. Multi Mode Optical Fiber Used to transmit many signals per fiber. (Multi Mode fibers are generally used for computer networks, lan applications). MultiMode Optical Fiber is produced as 50/125 and 62.5/125. (Core/Cladding diameter in microns.) Single Mode Optical Fiber Used to transmit one signal per fiber (Single Mode fibers are generally used for telephone and cable tv applications.) Single Mode Optical Fiber is produced as 8/125 and… Read More
You will need a special card for each PC that would convert the communication signals (electrical signals) into optical code. Then you would connect the optical ports of both machines together via fiber optic cable. Ideally one card (one per machine) would be able to transmit and receive optical code over two strands of fiber. One strand for transmit the other for receive.
Yes, that is true - and that is commonly used in modern technology, but especially to transmit information. Note that in an optic fiber, light travelling along the fiber is simply reflected back inside, if it reaches the borders.
Optical fibers are utilized regularly as a way to transmit light between the two finishes of the fiber and find wide use in fiber-optic correspondences, where they allow transmission over longer separations and at higher transfer speeds (information rates) than wire links.
To be perfectly technical, the answer to this question would have to be 'yes', but only because light and radio are the same physical phenomenon. The optical fiber only conducts the electromagnetic waves that we usually describe as "light". The waves that we normally describe as "radio" cannot pass through optical fiber.
As far as I know, these are not compatible or comparable systems of transmission. Optical fiber is used to transmit digitally encoded light pulses (data). Waveguide is used to transmit radio frequency (RF) energy. There aren't advantages of one over the other because they cannot be used for the same thing.
A fiber optic cable is a bundle of many hair thin threads of glass. Light is shined through these tiny glass threads to transmit data.
The main reasons are :- Speed - Optical fibre cables can transmit data at much higher rates than copper cable. Capacity - You can transmit more than on signal simultaneously in a single optical cable. Security - Optical cable is virtually impossible to 'tap' without being detected.
Fiber optic cable is constructed out of glass or plastic, and uses light pulses to transmit data. Copper cable is made out of copper material (not glass or plastic) and uses electrical voltages to transmit signals.
Optical fibre typically can transmit data at the rate of 1 Gigabit (1024 Megabits) per second
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… Read More
There are actually about 10 types of Fiber Optic Cables. OFC: Optical fiber, conductive OFN: Optical fiber, nonconductive OFCG: Optical fiber, conductive, general use OFNG: Optical fiber, nonconductive, general use OFCP: Optical fiber, conductive, plenum OFNP: Optical fiber, nonconductive, plenum OFCR: Optical fiber, conductive, riser OFNR: Optical fiber, nonconductive, riser OPGW: Optical fiber composite overhead ground wire ADSS: All-Dielectric Self-Supporting
It was 1975.
1) Plastic (Polymer) Optical Fiber is used to transmit signals down a flexible, plastic material. 2) Polycarbonate coatings are used on optical discs to prevent scratching the underlying surface that has the actual pits and lands.
first of all we should know the coupling efficiency. suppose that the Pf is the power coupled into a fiber and Ps is the power from the led source , then the efficiency is give by Pf / Ps. it also depends on the radius of the recipient fiber core. The launching of optical power into a fiber also depends on the type of led we are considering.
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of itsadvantages over electrical transmission, optical fibers have largely replaced copper wire communications… Read More
Surely not fiber optics cant be used to send electricity through them it can transmit only optical signals that is light signals... and it can be used for long distance communication under sea transmission and so on...
No. Fiber Optic or Optical fiber is a flexible, transparent fiber made of glass (silica) or plastic. It transmits information using pulses of light.
An optical laser is modulated and used as the transmitter in optical fiber communication.
Hi, Fiber Optics transmit signal using lights rather than electic current, so when signal passes though an optical fiber cable, it does not generate electric or magnetic field around it, and it is not affected by surrounding magnetic or electric fields Adv of optical fiber is that they are immune to noise, signal passes at lights speed, and no signal power is lost along the transmission line.
optical fibers are strands of glass or plastic that use light to pass information. It is very fast and is not disturbed by electromagnetic fields.
# Optical fibres can carry more information as opposed to conventional cables. # Optical fibres are not affected by radio frequency interferrence # Information carried in an optical fibre can only be tapped physically (to steal information, the thief has to work on the optical fibre so that the light will travel to the thief)
it is the creteria for the number of modes in optical fiber
An optical fiber sensor can be used for just about anything a "regular" sensor can be used for. There are hundreds of sensors, and they can be made to communicate over optical fiber.

Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
Optical fiber is conducting light, not electricity.
Optical fiber is not sensitive to electrical, magnetic or static interference
A transmitter sends light down optical fiber
A break in the cable would interrupt signal in optical fiber.
An objective type of question on optical fiber is on that focuses on the integral part of fiber optic. A good question would be, " Why are optical fibers immune to EMI? "
To transmit data, you need several things, including:* A source of power * A protocol * A medium, such as a cable or fiber optic * Some sort of device that does the transmitting and receiving * The data itself
The advantage of wireless communication over optical fiber are as follows : the cost of wireless communication is much less over optical fiber communication : unlimited no of users can be installed which is not so easier in Optical fibers : maintanence of wireless communcation system is cheaper than Optical fiber communication.
Medical Uses: Optical fibers are used in number of instruments that enable doctors to view internal body parts without having to perform surgery. They can be made in extremely thin flexible strands for insertion into the blood vessels, lungs and other parts of the body Communication: Telephone transmission method uses fiber optic cables.

Usually, there is a laser diode that is optically coupled to the fiber.
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
An optical fiber. Optical fibers are made of thin transparent glass or plastics that take and transmit data in the form of light, at the speed of light (whatever it is in that respective medium). Very less losses occur during data transmission, although repeaters are used after great distances to rejuvenate the signal.
optical fiber is made from extremely pure glass that is stretched out to a very thin and flexible wire. fiber optic wire is often used in locations of computer networks with a very high load because of the speed of light. it simply uses the same hexidecimal and binary codes to transmit data over the network just like regular Ethernet cables, except much much much faster.
All optical cables will sound almost exactly alike. There is no reason to spend a lot on these. Usually you get better shielding and performance by spending more, but optical signals are not interrupted by any source of outside interference. HDMI cables are similar, as it transmit a digital signal, a very inexpensice HDMI cable will yield the same results as the most expensive.

In a fiber you don't want any reflection. You just want efficient transmission of information. Fiber that is bent too much bleeds to light into the cladding. You must polish fiber when joining it to another.
Fiber-optic communication refers to the transmission of information using optical fiber. Opto-electronic repeaters are used to convert fiber optic light transmissions to electrical signals.
