...Unit 8. Lab 1. Fiber Optic Connector Assembly Fiber Stripping “The outer sheath of fiber cables can be removed using electrical cable stripping tools, and scissors or a razor blade can trim the Kevlar strength member. However, the fiber coating must be very carefully removed to avoid damaging the fiber, surface flaws and scratches are the cause of most fiber failures. The coating can be removed using fiber strippers.” (Newport, nd) Fiber Termination “End-face surface quality is one of the most important factors affecting fiber connector and splice losses. Quality end-faces can be obtained by polishing or by cleaving. Polishing is employed in connector terminations when the fiber is secured in a ferrule by epoxy.” (Newport, nd) Fiber Cleaving “Fiber Cleaving is the fastest way to achieve a mirror-flat fiber end and it takes only seconds. The basic principle involves placing the fiber under tension, scribing with a diamond or carbide blade perpendicular to the axis, and then pulling the fiber apart to produce a clean break.” (Newport, nd) “Once the optical fiber is terminated with a particular connector, the connector end-face preparation will determine what the connector return loss, also known as back reflection, will be. The back reflection is the ratio between the light propagating through the connector in the forward direction and the light reflected back into the light source by the connector surface.” (Newport, nd) “Minimizing back reflection is of great importance...

...Unit 8. Lab 1. Fiber Optic Connector Assembly The most critical part, the Cable and Fiber Preparation where the fiber is mounted, is the ferrule. The Ferrule is a long, thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber's cladding diameter which is usually 125um. When fiber connector ferrules are made from several types of materials including ceramic(Zirconia), stainless steel and plastic. The ferrule's job is to center and align the fiber and protects it from mechanical damage. The end of fiber is at the end of the ferrule, where the fiber end is polished smooth either flat or with a curvature. The ferrule is mounted in the connector body and then the connector body is attached to the fiber optic cable structure. Finally, a strain-relief rubber boot protects the connector-cable junction. Fiber optic connectors usually do not have the male-female polarity. Most fiber connectors are male only. Instead, fiber connectors mate to each other in fiber adapters, which are often called mating sleeves or coupling receptacles. Fiber optic adapters used to mate different connector types such as a FC connector to a SC connector are called hybrid adapters. Although this approach requires the use of separate adapters, it otherwise reduces fiber connector inventory requirements since now you need to stock one type of connector only. Another advantage is that fiber adapters can be designed to mate one type of connector to another, which is a big...

...Ports and Connectors There are many ports and connectors to a computer. The ports are; Serial, Parallel, and Game Ports. A serial port transfers 1 bit of data at a time and is a male port that has 9 or 25 pins, where as a parallel port transfers 8 bits at a time and is a female port with 25 pins, and a game port is a female port as well that has 15 pins laid out in 2 rows. Most computers have now replaced these with USB ports. There are two different USB (Universal Serial Bus) ports. USB port 1, transfers 12 Mbps and is 3 meters wide. USB port 2, transfers 480Mbps and is 5 meters wide. USB connectors come in two sizes, A-connector, and a B-connector, which is the smaller connector. A mouse and keyboard both use a PS/2 port but are now using a USB port wireless. USB can have a limit of 127 devices plugged in at the same time. NIC (Network Interface Card) converts parallel communication to serial and uses an RJ-45 connector. A Modem connects to the phone line but is the slowest way to connect to the internet. It has a transfer speed of 56kbps but V.92 is quicker and it converts analog into digital. The Modem uses a RJ-11 connector. Computers come with two input/ output connections, VGA that has an analog interface that is a D-type connector that has 15 pins laid out in 3 rows, a DVI that is a digital visual interface, and a S-video that connects to the T.V. and that is round with 4 or 7 pins. An SCSI has 2 different connectors narrow and wide. The narrow connector also known...

... Connector Installations Twisted-pair cable: Step 1: Measure the cable you want to put ends on and trim it to the proper length using the cable cutter. Step 2: Use the cable stripper to strip about 1.5" of the jacket from the end of the cable. Then, rotate the stripper around the cable twice. This will cut through the jacket. Step 3: Remove the stripper from the cable and pull the trimmed jacket from the cable, exposing the inner conductors. If a jacket slitting cord (usually a white thread) is present, separate it from the conductors and trim it back to the edge of the jacket. Step 4: Untwist all the inner conductor pairs and spread them apart so that you can see each individual conductor. Step 5: Line up the individual conductors so that the color code matches the color-coding standard you are using. Step 6: This step includes two points. First, trim the conductors so that the ends are even with each other, making sure that the jacket of the cable will be inside the connector. Second, the total length of exposed connectors after trimming should be no longer than 0.5" to 0.625". Step 7: Insert the conductors in the connector, ensuring that all conductors line up properly with the pins as they were in the previous step. If they don't line up, pull them out and line up. Do this carefully, as it's the last step before crimping on the connector. Step 8: Carefully insert the connector and cable into the crimping tool,...

...Connector Installations * Strip the cable of its protective outside jacket about 3-6 inches from the end. This can be done with the cabling scissors by applying pressure from the scissors to the cable and rotating the scissors around the cable. After you have punctured the cables jacket, you should be able pull the jacket off easily leaving exposed wires. * Expose the wire a little further. Stripping the cable can cut and damage the wires at the area that we cut the cable so we want to expose about 6 more inches of fresh wires. Most twisted pair cables have a small string inside the cable to assist with this. * If your cable has the small string. Cut the string after you have enough exposed cable. * Untwist the wires completely to the jacket. Place the wires into the appropriate color slot on the jack. Make sure to place the wires as tightly as possible in the slots in regards to the jacket. There should be as little exposed and untwisted wire as possible to keep the signal strength as high as possible. Make sure to place the White/Blue in the White/Blue spot and not the solid Blue spot. The White/Color wire is not the same as the solid color. * Terminate each wire. After all the wires are in the correct spot and double checked to make sure as little amount of exposed wires will be left as possible, use the punch down tool with the 110 blade and terminate each wire individually. The 110 blade will fully cover the wire connector on the jack. Push down until...

...Land use is one of the major issues we are facing in our time today, not only is it an issue of using lands to the advantage of building roads and highways, it is also the cause of global warming, the danger to environmental life and the cost of building the Intercounty Connector, known as the ICC. This issue is what may be called a problem by the residents of the counties of Maryland. The project of building the Intercounty Connector “ICC”, includes building a highway throughout a couple of the counties in Maryland to have a faster and more efficient flow of traffic, which could also endanger the environment, and cause global warming. Also it is going to delay traffic while the project is under construction. There are many reasons why this ICC project caught my attention. First, the use of land. Second, the environmental issues that we are facing today. And finally, the budget was used to build the project. But as always there is an opposing view to every project. Some who were supporting the idea of the ICC gave their lands to the county to build this project, which was not a good plan. Although they do not see the problems of giving away their lands right now, but they are coming. The loss of land will affect people in the future. The ICC project got a final approval from the Gov. of Maryland, and it has won its case against any opposing views. Still the ICC should not have been approved. In the case of the ICC project, there were many views concerning the environmental side...

Justifique com evidências sua avaliação. A diferença de custos considerando que a planta da DJC esta baseada no Japão é de 22,8% menor com relação ao custo da ACC. [pic] Para fazer um analise anulando a diferença entre os mercados é utilizada a tabela de índice de custo US / Japão: [pic] Se a planta da DJC começa a produzir nos EUA a diferença seria de -40,1% menor com relação ao custo da ACC, isto utilizando os índices de custo dos EUA com relação ao Japão. [pic] • Quais são as fontes dessas diferenças? Em que percentual cada possível fonte explica a diferença total? Quais as evidências de sua avaliação? O melhor cenário para analisar as diferenças seria no cenário em que a DJC começa a produzir nos EUA para excluir da analise o impacto da diferença dos custos dos fatores de produção no Japão com relação aos EUA. Só o fato de começar a produzir nos EUA geraria para a DJC uma redução nos custos de 22% (20,2 vs 26,1).

...Case 1: American Connector Company 1. erious is the threat of DJC to American Connector Company? How s Regarding the AC Company, we can see that the market place they have been occupying the last years is changing. As their competitive advantage was the quality and customizable flexibility, and regarding that their finance people is no more letting them to buy the latest production equipment, their position in the market is going to suffer changes. In the long term, they will definitely lose their competitive advantage. On the other hand, both companies are different, and take different shares of the market. Since ACC takes the quality and quality share and DJC takes the mass production and lowcost share. Apparently there is no threat, however there is. This threat is real at the moment that the market suffers any change. If the demand for lowcost products increases and wins positions respect quality and performance, the AC Company will be automatically out. It is important to notice that this may happen even if DJC does not run a new plant in the USA. Considering this, the potential existence of a new plant, specifically focused in lowcost and massproduction performance, in the US market could be destroyer. If the new plant gets to be built, the customers may consider the option of adjust themselves to the new plant connectors, despite of the fact that previously they were continuously demanding new designs. The only way this may happened is in case the ...

...Jonathan Hunt 7/23/14 Unit 6 Assignment 1 Cable Testers After installing cables in a building it is necessary to test them to make sure they are functional and did not get damaged during the install. There are many tools that can be used for testing cables, the type of cable that you are working with will determine the kind of tester that you will need. When working with copper cables one of the tools you can use is a tone generator, this tool can be used to test cables for crossovers, and shorts. This tool is most commonly used for testing punch down blocks in telecommunication lines. Another tool that is handy for copper wires is a wire map tester. You can use this tool to send a signal down the cable and make sure that the pin connections on both sides are correct. This tool can also detect a short in a wire as well as openings in the line. This is a fairly inexpensive tool and would be a good one to include in your kit if you are installing cables. Continuity testers can also be used in place of a wire map tester and are also inexpensive. It would be recommended to have at least one of these tools in your toolkit. Personally I would choose the wire map tester. If you are working with fiber optic cables you need to have a completely different set of tools because you are now dealing with light transmission as opposed to electrical current. Fiber optic power meters are used to detect the strength of light going down the cable. Depending on the type of fiber that you...
