Why optical fiber is slowly replacing copper cables in telecommunications?

Copper wire passes computer communications through the use of modulated carrier waves. RF energy is susceptible to resistance which reduces the signal over distance according to the Rho value of the copper wire. The longer the wire the higher the resistance the less signal is received at the other end.
Secondly, being an RF signal, copper wire is susceptible to receiving signals from other sources which can cause interference though inter-modulation products caused by phase sum and difference between competing signals.
Thirdly, RF signals are subject to standing waves which are caused by mismatches between feeders. This mismatch can prevent the signal from leaving the feeder (Copper wire) which in turn can prevent the signal from being received at the other end and cause the transmitter amplifier to become stressed and fail.
Finally, copper wire is limited in the speed of the signal which can be transmitted.
Fibre optical cable
With multi-frequency fibre cables multiple signals can be sent down one cable at one time. Dependent on the purity for the fibre cable there is very little optical resistance runs of over 20km can be easily achieved.
There is no transmission frequency limit to light.
There is no standing wave problem.
There is no interference problem from external sources.
Fibre bundles carry more signals that the equivalent copper wire bundle in less physical space.

∙ 11y agoThe 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.

What is a common use of Cu?
The most common use for copper (Cu) - is in electrical cables.
Why does copper need to be purified?
Extracted copper contains many impurities which may change the properties of copper besides decreasing its tensile strength,ductility etc.Hence it needs to be purified.
Which property of metals makes copper good for electricity cables?
Metals and particularly copper, are good conductors of electricity a prerequisite for an electric cable. In addition, they are ductile enabling them to be drawn out easily into wire/cable.
Is gold a conducter or insulater?
Gold is a conductor. Most of the more expensive audio cables have gold plated tips because gold is a better conductor than copper.
What Is a metal string that brings electricity to our house?
Electricity is brought into our homes along cables of conductive copper wires insulated against shortening by an insulating covering of plastic.
Why copper cables are transformed into optical fiber?
fibre has higher data capacity, takes less space, is cheaper, etc. than copper.
Can Aluminum mylar-tape-shielded cables be used instead of Copper braid-shielded cables for instrumentation cables?
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
What difference between copper cable and optical cable?
A copper cable transports electrical signals. An optical cable transports light signals.
What is the element that is used for eletrical cables?
copper
What kind of wire is in PC ribbon cables?
Computer cables are often made of copper.
What will diplace copper from copper sulphate soluctions?
Any metal more reactive than copper can be the replacing metal in copper sulfate solution reactions. Iron and zinc are the most common metals replacing copper in these reactions.

Why optical fiber is slowly replacing copper cables in telecommunicaton?
Fiber lasts longer than copper, it has less signal attenuation, and its bandwidth capacity is much greater. It's just an all around better medium than copper. Plus, it costs almost exactly the same to deploy fiber as it does copper in new outside plant deployments - so you get all the benefits of fiber for no additional cost.
What are the alternatives to optical fibers?
Copper wires and satellite transmission.
Booster cables - what is the difference in use between copper cald aluminum and 100 copper wire?
It depends on some factors which are not mentioned in the question. The main difference between 100% copper wire and copper clad aluminum is that IF they are the same diameter, then the copper will carry and stand up to more electrical current than the aluminum. If the diameter of the aluminum cables have been upgraded in size, to match the current carrying capacity of the normal copper cables, then the only remaining difference is that copper withstands much more bending and coiling beforethe metal begins to "work harden," and some of the individual wire strands begin to break. In other words, the copper stands up to use better than aluminum. When buying booster cables, read the lables, and make sure that the maximum number of Amps, for which the aluminum cables are capable of carrying, is equal to or greater than the highest rated copper cables. Therefore, IF the copper clad aluminum cables are rated for the same current carrying capacity as copper cables, then there is NO difference in use between the two types.
