...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 copper wiring is...

...Wired and Wireless Communication Channels Kaplan University Assignment: Wired and Wireless Communication Channels Rudy Chavez February 19, 2013 Course: IT 331 Technology Infrastructure Instructor: Prof. James 1. You have been asked to design a LAN with operation over a distance of about 100m. Compare and contrast twisted pair cable, coaxial cable, fiber-optics, and wireless for this application. You should create a table or flow chart which would facilitate choosing between these options depending on circumstances. The table or flow chart should be submitted as part of your document. You may not submit a separate file. The choice of media to be used for a network that spans 100 meters depends upon several factors and requirements that include cost, ease of installation, environmental factors such as the need to trench and EMI or Electromagnetic Interference, performance and attenuation, security, and network fault tolerance. Regarding each type of media (includes the supporting network devices), the least expensive would be an unshielded twisted pair in the form of CAT 5 or 6, which is also generally the least expensive to install (flexible cable and lower cost network equipment), but not resistant to environmental factors such as EMI (unless the more expensive shielded variety is used). A twisted pair does support higher network speeds, up to 1000 Mbps over the 100 meter distance. Coaxial cable would be more expensive to install than twisted pair due to higher...

...circuits because they are dedicated to the use of these two computers. This type of configuration is used when the computers generate enough data to fill the capacity of the communication circuit. This can get very expensive, particularly if there is some distance between the computers. 3. Describe Three types of guided media. Guided media are those in which the message flows through a physical media such as a twisted pair wire, coaxial cable, or fiber-optic cable. a. Twisted pair wire is most commonly used. It is a pair of wires used in standard telephone wiring. They are twisted to reduce interference caused by the other twisted pairs in the same cable bundle. Twisted-pair wires go from homes and offices to the telephone company end office. b. Coaxial cable is a type of guided media that is quickly disappearing. It is an insulated wire that runs through the middle of a cable. A second braided wire surrounds the insulation of the inner wire like a sheath. Used on LANs for transmitting message between devices c. Fiber-optic-cable also is...

...commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network. There's a lot of different type of cabling in today's networks and I am not going to cover all of them, but I will be talking about the most common cables, which include UTP CAT5 straight through and crossover, coax and a few more. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed in a shield that functions as a ground. This is known as shielded twisted pair (STP). Ordinary wire to the home is unshielded twisted pair (UTP). Twisted pair is now frequently installed with two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for modem use) when you need it. Twisted pair comes with each pair...

...INTRODUCTION 2.1 REPORT OUTLINE Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the1970s, fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world. Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals....

...Courtney Patin Week 1 Telecommunications Exercise 1) Local Loop a. The local loop is the physical wiring that connects you to the public switched telephone network (PSTN). This line can be a voice line, or it can be a data line. The physical wiring for the local loop consists of a pair of twisted copper wires that run from the telephone company's central office (CO) to the subscriber’s premise and another pair of twisted copper wires that run back to the telephone company’s CO. 2) Central Office a. In telephone communication in the United States, a central office (CO) is an office in a locality to which subscriber home and business lines are connected on what is called local loop. The central office has switching equipment that can switch calls locally or to long-distance carrier phone offices. In other countries, the term public exchanges is used. 3) Local Exchanges a. A local exchange carrier (LEC) is the term used in the U.S. for describing the telephone company which operates within a local area and provides telecommunication services within that area. a.i. Local exchange carriers started across the U.S. following the breakup of the Bell system due to antitrust regulations. Local exchange carriers are allowed only to handle local calls, and not any long-distance traffic. 4) POP a. Point of presence (POP) is the point at which two or more different networks or communication devices build a connection with each other. POP mainly refers to an access point, location...

Describe a local land line phone system based on the following Landline Telephone Components: I would place a call using my phone which is connected to the jack by a fixed line, the data would be sent to my service providers Central office via Local Loop, once the data has reached the CO and depending where my call was going it would be transferred to the local exchange for local calls and long distance, and for long distance calls it would be transferred at the POP to the Long distance System. *NOTE* I was unsure about the question so I defined the components and described a local line phone system. a.) Local Loop: is a loop of copper wire that allows current to flow from the telephone to the central office and back. It is the dual-wire physical interface that connects a telephone to the CO (central office). b.) Central Office: also referred to as the local exchange, which provides services to a group of subscribers in a local area. c.) Local Exchanges: Local exchanges are local telephone companies that provide service along with other Local Exchanges within a designated geographical area. d.) POP: Point of Presence, is the point where a local exchange carrier (LEC) or a long distance carrier meets another long distance carrier. The POP also provides a connection to the interexchange carrier (IXC). e.) Long Distance System: long-distance service is provided...
