Fiber Optic cables do not use copper wires; they use either glass or plastic for the transmission medium.
Aluminium is also used in certain applications, instead of copper, as it is cheaper although very slightly less conductive.
I don't know the present situation, but aluminium-cored wires were introduced into the British telephone networks in the 1970s, at least for local distribution; whilst aluminium bar material was used for the main bus-bars supplying low-voltage power to the switches in the telephone exchanges.

Why do you use copper in wires?
we use copper in wires because it is a conductor of both heat and electricity
What is the meaning of YFY and YWY in copper cables?
YFY stands for "flexible copper cable," which is typically used for applications requiring flexible installation. YWY stands for "indoor copper cable," which is used for fixed installations indoors. Both types of cables are made of copper conductors but differ in their flexibility and intended use.
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.
Is it safe to use jumper cables with wires showing?
Never use cables with wires exposed. The wires can ground to the vehicle, start a fire or worse case, electrocute you to death. There is enough current going through the cables during cranking to weld steel(100+amps).
What are the types of cables use in lan?
optical fiber ,twited pai,coaxial cable
Can copper wires carry digital information?
Yes, this is done all the time. Category 5, category 5e, and category 6 are the most common copper cables used at this time. They are basically advanced versions of the original phone cable. Coax cable is another type of copper cable used to carry digital information. It is the cable the satellite dish and cable companies use and the most common type is RG-6. This cable is capable of faster data transfer speeds than the phone type cables.
Why are copper wires use in the motherboard?
because copper is a excellent conductor of electricity
How do you use BS767 IEE wiring regulations when selecting wires and cables?
easy just tape the cables together.
What are the different types of cables?
There are several types of video cables. These types include: coaxial cables, HDMI cables, component video,S-Video, and standard video cables. There are used to connect the various pieces of equipments that we use today.
Can you connect speaker wires to other speaker wires?
Yes with the proper tools you can splice two speaker wires together to extend the length of the wire. Be sure to use similar composition cable (copper to copper, silver to silver, etc) Wearing latex gloves to prevent corrosion form the oil on your skin strip 1/2in of the speaker cable sleeve on both cables. Twist the cables together and use silver solder to complete the bond. Apply heat-shrink of electrical tape to prevent the cable from shorting. Enjoy your new, longer cable.
How do you connect a PC to a lan using telephone cables?
You can't using telephone cables. Telephone cables use 4 wires, but none of the wires are twisted, so there will be problems with crosstalk. Also, telephone cables use an incorrect connector (RJ-11) for a NIC card in a PC, which needs RJ-45 connectors.
How many uses are there for copper?
there r only 2 uses1. copper is use inn wires.2. it is use for utensils.
