how the use of optic fibers in the place of copper wires reduces copper losses? Topic: how the use of optic fibers in the place of copper wires reduces copper losses?

Question: optic fibers are used for communication purposes instead of copper wires. the reason is that it reduces copper losses due to high frequency of the waves. How does optic fibers reduce the losses? do losses depend on frequency of the wave? since the equation for losses is given by I^2R the frequency has no role to play. is that so?

The copper loss is not the driving force behind the use of fiber optic cable instead of copper. The prime reason is the quantum leap in data quantity handling capacity the fiber optic cable has over copper. High frequency signals carried on copper wire tend to travel on the surface of the wire as opposed to using the whole area of the wire. This coupled with the very rapid reversal of the current on the surface results in hysteresis losses in the wire, which is a real power loss.

Usually people divide communication technologies by the means signal is transported. 1) Optic fibers use LIGHT. (usually infrared one). It is the most modern technology since it can operate at high frequencies of data transfer (i.e. tens Gigabit per second). 2) Any wires (not only copper ones, also aluminum, gold and others) use ELECTRON CURRENT. The speed of data transfer is limited because of imperfect electronics in devices. This technology is used in local networking as well as in telephone and telegraph. 3) Radio, TV, cell phones, wireless systems use ELECTROMAGNETIC WAVES (which is sort of light too, with much longer wavelength. E.g. optic fibers operate at wavelength of 1.55 micrometer while FM radio operates at meters). Anyway, when a device caches an electromagnetic wave from air it converts it to electric signal in wires so these technologies are interconnected, 4) Earlier ways of communication were less "physical" and not automated -- like messengers, mail and so on.

Fiber optics can carry many greater alerts in a unmarried fiber b) the sign attenuates some distance much less consistent with mile than in copper c) the kit deal would not grow to be brittle through getting older as copper does copper consists of static in the sign whilst in comparison with the organic fiber sign copper sign is slower in terms of mega bits consistent with 2d copper sign has a decrease sound frequency purity

No. Look up 'skin effect'. It's the effect where high frequency ac currents are concentrated in the surface area of a metallic conductor. As the frequency of the ac goes up, the cross sectional area of the wire available to conduct that current is effectively reduced, increasing the apparent resistance of the conductor.

I^R refers to the electrical characteristics of a wire. Since fiber optics aren't electrical (they use light pulses through glass instead), the only line losses you get are from impurities or inclusions in the glass fiber.

HI , I know one fiber optic products online store,it is b2c online store ,you can buy the fiber optic cleaning kits easily. The store name is Fiber store.
