Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser

any ore containing iron or iron compounds is called iron ore. However‚ in the industrial or commercial it not only contains iron composition but also has use value. It is difficult to determine whether the ore has commercial value‚ so it is difficult to make a unified iron ore standard. For example‚ the iron ore produced by the Europe has very poor quality‚ simply because they cannot find better ore‚ they call his ore as iron ore. In Australia there are large amount of high quality iron ore‚ so

At present‚ the raw materials to refine copper in China mainly are towanite‚ chalcocite‚ bornite‚ malachite and etc. According to the technical conditions of smelting‚ the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide‚ that is‚ sulfide ore‚ which contains less than 10% copper oxide；oxidized ore‚ which contains more than 30% copper oxide; mixed ore‚ which contains 10%~30% copper oxide. Copper is one of earliest metals that be found and used

Copper Sulphate Calibration Aim The objective of this experiment is to determine the unknown concentrations of solutions. Introduction With the use of absorption of light a spectrophotometer sends UV wavelengths through solutions to determine their concentrations. The light absorbed is measured as the atoms‚ molecules and ions absorb the wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower
