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.
What else can I help you with?
What causes copper cable turn black?
Copper cables can turn black due to oxidation, which is a natural process that occurs when copper is exposed to air and moisture. This leads to the formation of copper oxide on the surface, giving it a black color. Additionally, exposure to sulfur compounds in the environment can also contribute to the blackening of copper cables.
Which property of metals makes copper good for electricity cables?
Copper is a good conductor of electricity due to its high electrical conductivity, which allows electrical current to flow easily through the material with minimal resistance. This property makes copper ideal for use in electrical cables to efficiently transfer electricity over long distances.
What materials are being used to replace copper telephone and cable television lines?
Fiber-optic cables are commonly being used to replace copper telephone and cable television lines. These cables use light to transmit data at high speeds over long distances, offering faster and more reliable connections compared to copper lines. Additionally, some providers are exploring the use of wireless technology like 5G for delivering telephone and television services.
Why does copper need to be purified?
Copper needs to be purified to remove impurities such as sulfur, iron, and other metals that can affect its properties and performance. Purification ensures copper meets specific quality standards for various applications, such as electrical wiring, plumbing, and electronics. Additionally, purified copper is less likely to corrode or degrade over time.
Why does the blue colour remains blue during electrolysis of copper sulphate solution using copper electrodes?
During electrolysis of copper sulfate solution using copper electrodes, the blue color of the solution remains because copper ions from the copper sulfate solution plate onto the cathode, replacing the copper atoms in the electrode. This does not change the color of the solution as the copper ions remain in solution, maintaining the blue color.
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.

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.
What are the alternatives to optical fibers?
Copper wires and satellite transmission.
What consists of a single copper wire surrounded by at least three layers?
A single copper wire surrounded by at least three layers typically refers to a coaxial cable. The innermost layer is the copper conductor, followed by insulating layers, and an outer protective layer. Coaxial cables are commonly used in telecommunications and audio/video applications for their ability to transmit signals efficiently and with minimal interference.
