...00957058 Copper vs. Fiber There are two main forms of cable used in telecommunications, copper wire and fiber optic cable. Copper is a much more popular choice in most networking situations due to its inexpensive sticker price. Copper wire does pose certain issues that the more expensive and delicate counterpart does not. There is also a huge difference between the two cable types when it comes to performance and bandwidth. Copper wire is most commonly used in network construction and in cabling for home entertainment use. UTP (unshielded twisted pair) is a very commonly used cable used to connect network devices. It is very flexible and relatively inexpensive and thus is the most commonly used. Category 5,5e or 6e cables are used to connect client devices to a network and also are flexible and relatively inexpensive. Coaxial cables are a more rigid and durable cable that have a higher bandwidth than UTP or Cat 5, 5e or 6e cable. All of these cables use copper wiring which is flexible and cheap but will potential issues. Due to copper’s conductive properties it will cause grounding issues when wiring a building. Wiring outside with copper also causes potential hazards in regards to lightning strikes. There are opportunities when running cable for a network to use both types of cabling. When running cable in areas that are not subject to a lot of foot traffic, using fiber optic cable is best used due to the much larger bandwidth. Because of its fragility, fiber optic cable...

...decide between copper and fiber cabling, there are several things to think about for which one best will fit your needs. A few things you will need to take into consideration when making your decision are what do you need your cable to be capable of, how far do you need your cable to run from point to point, what is your budget, and always think about the future with room to expand your business. Both copper and fiber cabling have pros and cons. Copper cabling has been around ever since electricity was discovered and utilized in a day-to-day fashion. It was used mainly for telephone lines in the beginning of its “birth”. Copper cabling comes in many forms such as coaxial, CAT5e, CAT6, UTP (Unshielded Twisted Pair), and STP (Shielded Twisted Pair) to just name a few. Coaxial has been in use for the longest period of time and one of the first types used in networking. CAT5e is the most common used today in networking with the bandwidth it supports and is available in UTP or STP. CAT6 can support any application that “lower” cables can and also has a higher bandwidth and is available in UTP and STP as well. UTP is unshielded twisted pair, which means that the cables twisted together do not have any extra protection again EMI (Electromagnetic Interference). STP shielded twisted pair, which means that the cables twisted together have and extra metallic foil or multi-wire screen mesh that is used to reduce EMI. Copper cabling is much more cost effective than fiber, easy to install...

...monitoring of power transformer is very important. By measuring the furan contents in power transformer oil can give a sign of the power transformer health, using this method is more convenient and economical among all the methods. With the aid of UV-Vis Spectrometer, light absorption and transmission with various furan contents of different power transformers with different ages are measured and compared. The measured results are used to predict the furan contents and remnant life of the power transformer can estimate. Copper dusts added into transformer oil in order to investigate the effect on the light absorption and transmission. The measured results show the impact of copper dust on light absorption and transmission characteristics that can provide indication of transformers remaining health condition. This thesis presents the measurement of power transformers oil samples with different furan contents for remnant life estimation. Key words: Power Transformer, Copper Dust, Transformer oil, UV-Vis Spectrometer, Furan, Health Chapter 1 Introduction 1.1 Power Transformer Figure 1: A basic power transformer. Power Transformers are critical elements in an electrical power system. It is used to step-up or step-down voltage level as needed to serve the transmission or distribution networks.

...This paper is about Copper Cable versus Fiber Cable. Or Copper vs Fiber. Two completely different materials- One’s ancient, the other is almost as old. But in today’s modern environment, both are being used to carry signals through a system, namely computer networking or the larger system, the Internet. Just in a different manner. We’ll look at what Copper and Copper Cable is, what Fiber (glass) and Fiber Optic Cable is, how it’s used and the pros and cons between the two (2). Copper is one of the most important metals available. It’s a member of the Periodic Table of Elements, whose number is #29. It’s been used for thousands of years and has many uses. It’s second only to silver in electrical conductance. Today, Copper cable is a medium whose uses range from communications to the building industry to the electrical and electronics industry. Electrical wiring in buildings is the most important market for the copper industry. Roughly half of all copper mined is used to manufacture electrical wire and cable conductors. Copper used in building wire has a conductivity rating of 100% IACS (International Annealed Copper Standard) or better. Copper building wire requires less insulation and can be installed in smaller conduits than when lower conductivity conductors are used. Copper is also used to make communications wire (Telephone, Cable TV, and Ethernet) such as coaxial wire and Twisted Pair cables. Twisted pair cabling is...

...Fiber Optics: The Super Highway of Information We live in an information age. Broadband is the foundation of economic growth and telecommunications is making its mark in all parts of the world. It is what enables the internet that drives e-commerce, education and universal access to information. Rapidly increasing communication density in this growing field and the ever increasing information flow is resulting in massive expansion in worldwide networks. The need for quick and reliable transmission and retrieval of ever increasing volumes of information over great distances is getting more and more important every day. This paper explains the history, the fiber optic theory, and the future of worldwide fiber optics networks already in progress. One would normally think that fiber optics is relatively new to this century, but looking back in history, there are many concepts which lead to the creation of fiber optics. The transition to optics concurred with the conversion from analog to digital transmission in the telephone network and with the growing necessity of computer data transmission. Long before fiber optics was first discovered, many signals were carried through a copper coaxial cable. Invented by Oliver Heaviside in 1880, copper conductors are used for mostly analog signals, such as high frequency radio waves, cable television signals, and power lines (Nahin 1988). He determined by wrapping an insular layer around a transmission line both improves the quality of...

...Patton-Fuller Community Hospital Networking Project (Week 3) University of Phoenix CMGT 554/IT INFRASTRUCTURE Patton-Fuller Community Hospital Networking Project Today most new building construction is built with new technology and is not as much concerned with the type of budgets that a hospital muse consider in order to redesign a whole new network structure for the purpose of being more optimal and maintaining standards that keep up with advances in new technology. In most cases, a hospital’s network can transition over time with new technology and evolve into meeting the demands it requires to perform effectively. However, upgrading a hospital’s entire network can often be very expensive to implement and sustain. There may be a case where components or parts are no longer being produced to meet current and future demands. In the last several years, changes in healthcare put a demand on hospitals to maintain their networks with new, more efficient solutions that can enhance performance, keep cost low, but most one that is reliable . The Network architecture at Patton-Fuller hospital was designed for each department to rely on information flow between each department. In other words, if the accounting department needed information from the pharmacy or admissions in order to create invoices or insurance billing, it would be rely on those departments to share real time information through the network.

...The product I choose to be obsolescing is a landline also known as POTS (Plain Old Telephone Service). The landline phone has been on the decline and has been replaced with cellphones. In the late 90’s and early 2000s the landline was used to connect to the internet. To cellphones can be used as mobile hotspots to connect wirelessly to the internet using a laptop, notebook, Generation Y is contributing factor of the cellphone is now become a house phone. Consumers, who like the variety and the convenience of mobile phone allows the cellphone very accessible. According to The CDC statistics stated that one out of every four Americans has given up their landline phone and are now using their cellular phone exclusively. There are a few reasons why many consumers have, in huge numbers, ditched the hard-wired phone and relied solely on their cell phone. One of the reasons is that alternative means of communication have reduced the number of phone calls that phone users make. Many of these means of communication can be utilized via a cell phone. For example, many use their cell phone for obtaining and sending e-mail, messaging on Facebook and other social media sites, and SMS texting. The decline of landline phones and the rise in cell phone use does not simply mark a shift between one types of phone to another. The decline of the landline is also a reflection of how individuals have changed in our preferred means of communication. “The phone network is thus not just a technical infrastructure...

...The Benefits of Twisted Pair Cable July 28, 2012 The Benefits of Twisted Pair Cable The current network model that is being used by your company today is the peer to peer model. This model is an ideal selection for a company or organization when there are very few computers. Since your organization currently has 20 Windows peer to peer client computers I would like for you to consider moving towards the client server network modelOnce a peer-to-peer network grows beyond 10 computers, it will likely begin to suffer from performance and from administrative problems (Posey, 2000) In the client server network model network hosts have specific roles which are assigned to them. There are certain host that are assigned as servers, which will provide network resources to the workstations. Unlike the current peer to peer model that is supported in your organization today in which everyone workstation has the same or similar operating systems. There are several benefits for your organization to consider to transitioning to client server network model. One of the major benefits of the client server network model is scalability. Since we know the potential for this organization to double in size over the next two years scalability is a key factor. It’s very easy to expand the size of your network with client server model because it will be easy to just add on workstation. Everything is centralized to the server. This server will be the centralized...
