...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. Coaxial Cable is widely used for cable tv it has solid copper core with a Teflon insulation around that either a foil sleeve of a braided wire mesh and then the outer jacket Plenum is the space between the deck ant the false ceiling when it is used for HVAC Riser is a vertical shaft that allows you to run wires between two floors Rip Cord is installed in some wire it is also called the slitting cord it is meant to make it easier to split the jacket on the cable when more than 2” of the wire needs to be exposed.

...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...

...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...

...Leaky Tub Faucet- Not only do dripping tub faucets contribute to increased water bills, the constant echoes that they produce in their fiberglass or porcelain surroundings are akin to someone poking you in the brain repeatedly with a cotton swab. They are mind-piercingly obnoxious. Fixing a leaky tub faucet is mindlessly simple, however. The directions for doing so are given below. 1. Shut off the water supply. Some homes allow you to do so beneath the bathroom sink. If yours does not, you will need to shut off its main water supply. 2. With the water off, turn the faucet handles as though you were trying to draw a bath. This will siphon all excess water from the piping before you start. 3. Before you proceed, the faucet handles will need to be removed. Begin by prying off the handle inserts (plastic coverings) with a pocket knife or similar gadget. 4. Removing the inserts will reveal screws in the handles. Remove them with a screwdriver. 5. Disconnect the handles from the stems. If they are stuck together due to corrosion, try using a handle puller (a tool created for this very task). If the handle puller does not do the trick, you may need to call a plumber. 6. Once the handles are disconnected, the next step is to replace the washer. Begin by removing the seat washer screws from the stems and taking the old washers off (it may require a little bit of force to remove them). 7. Replace the old washers and seat washer screws (you will probably want to take them with you to the...

...Ways to Prevent a Burst Pipe A burst pipe can be a minor inconvenience or a major problem. Frozen pipes break because blockages cause downstream water pressure to increase, not because of expanding ice against the pipe wall. Burst pipes that go unnoticed can cause flooding, which may cause mold or rot. Therefore, following the three tips below will prevent burst pipes. Keep Faucets Running If the temperature really drops, homeowners should keep at least one faucet running at all times. This is because moving water prevents pipes from freezing. While this may feel wasteful, only a trickle of running faucet water should be enough. In some cases, a slow drip will be sufficient. In most houses, one running sink faucet is enough to prevent freezing...

... A lot of people have problems with their sinks, toilets, and pipes that are getting clog up. But there’s a plumbing tool called “Drain Auger”. Most people say that it’s very easy to use this tool. It helps remove all the clogs and blockages inside the drains. Drain Auger have a long snake looking body that’s flexible. Sometimes it can get stuck trying to pull up all the stuff that’s blocking the water that’s trying to go through inside the drain. Some plumbers have to take the risks of trying to go through with it. I have to twist the long snake down the drain. Then, I have to rewind the snake as you pull all the clogged stuff up from the drain. My creation can help you unclog any blockage that’s blocking your water from going down the drain. Now you won’t have to worry about no more clogged up drain. When I’m using one, I have to be careful how you’re lowering the snake down the drain, because most of the time it can be caught onto something. I also have to be careful how you are using it. How is my creation is going to help drain millions of people drains who’s counting on me and my creation. Well, my creation, I have to rotate the snake down the drain. I push the button so it can sucked up all the blockage that was clogged inside the drain. Then, push the rewind button so that the snake can come back up. Now your drain is clog free. My creation is going to look kind of like a vacuum. The reason why, because the snake is created with a hole to sucked the blockage up. There...

...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...

...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...

...to meet those demands of mobility, and also for the life of the wire so that it does not crack, break, fray or short. We had a job at a university where we moved flat panels on a track system to create different screen sizes, and for that we had to make sure the cable would meet the demand. Capacitance Cat 6 is not always better than Cat 5. If a video extender is made for Cat 5e, using Cat 6 may cause you a problem. The electrical properties are different, and the circuitry inside may not be able to reconcile the increased capacitance. You should confirm with the manufacturer before making a substitute in a Category cable. Jacket What type of jacket does your cable need? You have plenum, riser, PVC/non-plenum and direct burial. Plenum cable is often required in commercial work, especially in buildings where there are open-air returns; it is essential to meeting code. Integrators will often use riser grade at the riser, and then transfer to plenum in the plenum space. This saves some cost, but I recommend you second-guess saving that few cents per foot in most cases. The chances of mixing up a box of cable and pulling riser in the plenum space may increase your liability as a company or cause you to re-pull cable when the inspector fails your install. If you only send plenum to site, you eliminate this possibility. A tennis ball would be a good makeshift tool because you can cut a hole in it to place wires...
