...Copper vs. Fiber Todd Gerger NT1310 Abstract In this paper we will be looking at the differences between Copper and Fiber optic cables. We will discuss the differences between the two and why many of the current networks in operation use fiber on the backbone between equipment and telecommunications rooms or enclosures. Copper vs. Fiber In the comparison between fiber and copper fiber, costs of the fiber cable has come down quite a bit. The cable itself has become easier to install as well since the invention of the flexible fiber which makes it easier to pull the cable through places. The flexible fiber has not become widely used vs. copper yet due to the need for the costs to come down for the connections, the NIC’s. the hub’s, routers and switches. Fiber Advantages The following advantages of fiber over other cabling systems are: (Oliviero 250) Immunity to electromagnetic interference (EMI), higher data rates, longer maximum distances, and better security. With copper cabling there is one common cabling problem they are susceptible to EMI. EMI is a stray electromagnetism that interferes with the signal. All electrical cables generate a magnetic field around their central axis. If you pass a metal conductor through a magnetic field an electrical field is generated in that conductor. When you place two cables next to one another EMI will cause cross-talk which is where signals from one cable is picked up on the other cable. Because fiber does not conduct electricity...

...NT1310 07/08/2013 Assignment 4 Contrast of Copper and Fiber Optics: Copper has been used in electric wiring since the invention of the electromagnet and the telegraph in the 1820s. The invention of the telephone in 1876 created further demand for copper wire as an electrical conductor. Copper wires in a cable may be bare or they may be plated to reduce oxidation with a thin layer of another metal, most often tin but sometimes gold or silver. Plating may lengthen wire life and makes soldering easier. Twisted pair and coaxial cables are made to reject electromagnetic interference, prevent radiation of signals, and to provide transmission lines with defined characteristics. Shielded cables are encased in foil or wire mesh. Fiber optic cable is one of the fastest-growing transmission mediums for both new cabling installations and upgrades, including backbone, horizontal, and even desktop applications. Fiber offers a number of advantages over copper. Fiber optics, though used extensively in the modern world, is a fairly simple, and relatively old, technology. Guiding of light by refraction, the principle that makes fiber optics possible, was first demonstrated by Daniel Colladon and Jacques Babinet in Paris in the early 1840s. John Tyndall included a demonstration of it in his public lectures in London, 12 years later. Unpigmented human hairs have also been shown to act as an optical fiber Below I explain how Fiber Optics is now the best solution...

...Armco Inc. Armco Inc is a steel manufacturer that used to be the sixth largest in its industry in United States in 1990. The Kansas City Works within its Midwestern Steel Division was hit by the decline in the business in the US steel industry. The firm produces grinding media and carbon wire rod. The first on has been successful in the industry with its great durability compared to the competitors. Carbon wire rods on the other hand were non profitable and covered only some of its fixed costs through its production volume. The old performance measurement system used by Armco Inc did not work properly because it had some problems. First, it did not provide information on the product mix being produced while it provided data on total tonnage produced but didn’t breakdown what was produced. Second the measurement system compared actual to objective but didn’t provide data on what factors exactly caused variance. Third, the costs were not broken down by fixed costs, variable costs and relevant range. Also the reports were generated on the 15th day following every month ending so I think managers could not take immediate corrective actions which would have been sometimes very necessary. In my opinion, also the fact that the system did not measure Key Performance Index for each department such as the new system, is one important reason why the old system was inadequate. there was inconsistency with organization’s current strategy. The objective of Armco Inc. is maximizing profits...

...rating Unshielded Twisted-Pair is copper wire that is used in a twisted pair. Which is two conductors of a single circuit that are twisted together to prevent crosstalk UTP typically have only one outer covering or jacket for one or more of the twisted pairs. Shielded Twisted-Pair is copper wire that is almost the same but also with the outer covering each twisted pair is also shielded separately and then shielded again before the outer jacket Fiber-Optic Cable bandwidth is dramatically higher than with copper speeds and it uses a strand of glass or plastic to transmit data using light pulses transmission distances are much further away it is not susceptible to outside EMI or crosstalk interference. It is more secure than copper wire it very hard to tap in to unlike copper wire. Dark Fiber is just a term used for unused or unneeded strands of installed fiber because you always want to install more than you need cause networks always grow.

...Breaking Tradition Will fiber ever make it to the desktop? This article is basically is about the differences between copper network infrastructure cabling and fiber-optic cable. Although it is overall cheaper to install and obtain fiber-optic cable companies are still electing to us copper networking. The reason that copper is still on top is because the companies that manufacture it are making sure that copper wire is still being made specifically for certain infrastructures. Copper wiring also seems to be a lot easier to work with for the time being due to lack of engineering economical of the 24 or 48 port fibers switches. I think that quality of the information was short, sweet and to the point. This article was not overloaded with information. If also was not difficult for anyone person to understand the point of it. I do not know much about the in and outs of computers. Even less about the behind screens of putting the network and the hardware together. I think the way the article was presented was done very well. Personally, I think that it take time for people get on broad with new technology. In my opinion, this article seems to be well informative. Also in reading the material it was very descriptive in regards to the contrast between copper cabling and fiber-optic cable. It went into detail regarding both the pros and cons between for the use of fiber-optic cable. However at the end of the article the writer proceeds to states that he feels that...

...types of cables and their abilities. The capabilities of these types of wires, prices, availability, and future uses are important factors to take into consideration when designing a layout for a building. Some other important variables to consider are how many people are trained to install the cabling and how durable that cabling is and how it can withstand long term use. Copper cabling is the widely used standard of today. It has been used as a communications line since the first telegraphs. Over the years it has developed into thin multi lined cables that can send an abundant amount of data. Since it has been around so long it is widely understood and taught to professionals as well as your average Joe. Category 5e and 6 are both capable of sending signal speeds much faster than we are able to produce at bandwidths that we haven’t reached yet. So at least for the near future copper cabling can still sustain Moore’s law. This law states that technology will double in capacity and for half of the price every two years. While copper is inexpensive now it becomes more expensive with its wide use. Also its abundance will degrade over time as it is used commercially worldwide. Some more of the flaws that are involved with copper are EMI, unnoticeable tampering, and potential. Electromagnetic interference can cause signal delay and corruption as it effects copper wiring. Tampering is easy to do since these wires are easily penetrated and will continue the signal down the trunk line...

...signal loss and check for equipment that may cause interference and degrade network performance. The following paragraphs describe three (3) cable testers and how they work and which cable system(s) they are most suitable for. The first tester is the wire-mapper. Wire-mappers are used primarily with copper twisted-pair cable installations. These devices, according to Oliviero and Woodward (2011, p.422, 441) “Transmit signals through each pair in a twisted-pair cable to determine if it is connected correctly to the correct pin at each end.” The second tool is the tone generator. A tone generator is a two-piece unit that consists of a tone generator and a probe. This type of tester's primary function, amongst installers, is to identify specific locations in a punch-down block then label accordingly. According to Oliviero and Woodward (2011, p.442-443), these testers “Transmit[s] a signal, or, with an alligator clip, you connect the unit to an individual wire. The other unit is an inductive amplifier, which is a pen-like probe that emits an audible tone when touched to the other end of the conductor.” Primary functions are identify a particular cable within a bundle and to test for opens, shorts, and miswires of individual wires. Unfortunately, there is a disadvantage to using this device; time consuming. The third and final tester to be discussed are Multifunction Cable Scanners (commonly referred to as a certification tool). Alarmingly, these devices are highly expensive...

Why is it important for operating system venders to consider the OSI/RM when developing networking software? The OSI/RM allows systems from various venders to communicate with one another. Significant deviance from the OSI/RM will result in communication failures. 7. What is the difference between routable and non-routable protocols? Routable protocols can pass through a router and can travel through LANs and WANs. Non-routable protocols use predefined routes that cannot be changed. 8. Name the two types of twisted-pair cable, and the two varieties of wire available for each. Shielded twisted-pair cable (STP) and unshielded twisted-pair cable (UTP). They both come in either stranded wire or solid wire. 9. What are the two major types of fiber-optic cables? Single mode and Multi Mode 10.

...Review 4.1 It allows the ability to wire the cables however you would like without having to create a crossover. so that the cabling can have a strong signal. If you put it at the end it will have send a weaker signal than by putting it a little closer, inevitably giving you less packet and data loss. It cuts down the bandwidth and speed of the connections the more you add. Review 4.2 the bend radius is the amount a fiber optic cable that can be bent without worry of breakage. The current recommendation is to have the bend radius no smaller than 20 times the cable diameter. Some cables will have a fiberglass rod for stability, a larger jacket around each cable, Kevlar is sometimes used, and tight buffer coating. Review 4.3 Legacy equipment such as current home scenarios require UTP. But if you are going far distances than fiber is most definantly the way to go. I would have the audio/video put onto one wireless ap and then a second for the remaining computers in the office. If it is a small business I would have 2 wireless AP setup at either end of the building as well. Review 4.4 the divide and conquer has you test each layer of the osi model and then decide where the trouble is coming from and than work up/down from there. Most times it is the hardware or software that is breaking connection or needs setup rather than a cable issue. Though if you have a high traffic area there are times that cables could become...
