Fiber optic is reliable with networking. I mean† how is it been secure† - Essay Example In a relatively short amount of time, a vast number of households and companies shifting from cable wires to this technological option. So just what makes this piece of technology so indispensable today? In a study from the Sans Institute Reading Room site, it says that fiber optic cables "can go an average of 62 miles versus 1.2 miles that copper can go before the signal needs to be regenerated or boosted."   (Witcher, â€Å"Option 1†¦Ã¢â‚¬ ) Fiber optic cables also do not conduct electricity, since they are not metallic, which makes them less interfered by radio frequencies, electromagnetic interferences, or even lightning. They are also smaller and lighter than copper wires, and are not affected by atmospheric conditions making them even more "installation-friendly" to areas that copper wires cannot go. With all these, plus the fact that fiber optic cables do not produce electrical radiation, fiber optics has been the choice solution for a better and a more secure means of communication by companies across the globe. However, it is not all good news. Through the years, research has proven that fiber optic cables can be easily tapped. One, which is the easiest, is called splicing. Splicing is done by an inserted apparatus intercepting a signal while it is currently transmitting data to an end party.   However, this method is easily detectable by most network security systems.  Another method of getting data from fiber optic cables is through splitters and couplers. This method is done by slightly  bending, crooking or putting a clamp on an optical fibers length so that light photons will leak into the tappers receiving device.   Lastly, there are the non-touch methods. The more advanced of these methods are able to derive the underlying optical signal by understanding the interactions between the fiber plant and the extra light added into it. Without any physical-layer optical signal protection,
