...Activity 1: Building a New Structure – Problem Analysis Here are the most common causes of fiber network malfunctions: • Broken fibers because of physical stress or excessive bending • Insufficient transmitting power • Excessive signal loss due to a cable span that’s too long • Excessive signal loss due to a contaminated connector • Excessive signal loss due to faulty splices or connectors • Excessive signal loss due to having too many splices or connectors • Faulty connection of fiber to the patch panel or in the splice tray Typically, if a connection is completely dead, it’s because of a break in the cable. However, if the connection is intermittent, there are several possible causes: • The cable’s attenuation may be too high because of poor quality splices or too many splices. • Things like dust, fingerprints, scratches, and humidity can contaminate connectors. • There is low transmitter strength. • There are bad connections in the wiring closet. Some tools to assist in determining the issue with the network would be: Cable fault finder - fault locator, cable and wire manager and tone generator Electrical Contractor Telecom Kits - these kits contain essential industry standard telecommunications tools and test equipment. Voltage Detector - provides protection against hazardous voltages. Punchdown Tool - termination tool allows you to terminate jacks. Modular Crimper Cable Strippers Once you find the problem, you have to repair it. Besides the...

...The Benefits of Twisted Pair Cable Introduction to Networking October 29, 2013 Ocper Inc. is a small company that has no one dedicated to information technology or networking on the staff, and there are 20 Windows peer-to-peer client computers all connected via coax cabling. The president has indicated that the company plans to double in size over the next two years, but she is weary of drastically changing the computing environment. This is my first assignment, but I feel that I have a very good plan to help give them a faster, more secure, and efficient network. The first change that I would recommend would be to move away from a peer-to-peer network to a client/server network. I would explain that there are many advantages to switching to a client/server network such as (Dean, 2009): * User logon accounts and passwords for anyone on a server-based network can be assigned in one place. * Access to multiple shared resources (such as data files or printers) can be centrally granted to a single user or groups of users. * Problems on the network can be monitored, diagnosed, and often fixed from one location. * Servers are optimized to handle heavy processing loads and dedicated to handling requests from clients, enabling faster response time. * Because of their efficient processing and larger disk storage, servers can connect more than a handful of computers on a network. The advantages of a client/server far outweigh any possible disadvantages. ...

...There are three domains that are affected by an “Internal Use Only” data classification standard. The three domains most affected by the classification are the: User domain, Workstation domain, and LAN domain. The User Domain: * Is made up of the people who can access the information system. With an AUP (Acceptable Use Policy) for this domain, any third party that requires access to the network must sign an AUP and a confidentiality agreement. This domain is considered one of the weakest and the most affected for a few reasons. 1st is the lack of user awareness to correct this you should conduct security training with all personal. 2nd if you have obvious security violations after that training then you need to place the employees on probation and review the AUP. 3rd when users are downloading various different files that do not conform to the established security guidelines then enabling content filtering and automatic antivirus scans would be wise. The Workstation Domain: * Is made up of the devices that employees use to connect to the IT infrastructure. Availability for this domain is necessary so that all employees can easily access any tools needed to perform their work duties. This domain requires strong security and controls because this is where users first access the system. It is also where sizeable damage to system can occur. Here are some problems the can happen with some corrective solutions. If you can have unauthorized user access situation;...

...Develop Production Database for Plant Operations Division Scott Peterson Columbia College Author Note This paper was prepared for Business Information Systems 393, taught by Ricky Martin Due 10 May 2012 Veracity Communications was formed, in 2002, by a small company called Off Campus Telecommunications. Veracity Communications was a provider offering phone, internet and cable services. One such company they contracted their services through was IProvo. IProvo was a public-private partnership located in Provo. The City of Provo constructed a fiber optic infrastructure that connected homes and business throughout the city as well as municipal, schools, etc. Provo city owned and maintained the fiber optic lines and equipment while privately owned companies, such as NuVont, Mstar and Veracity Communications, offered phone, internet and cable through IProvo’s network. Construction on IProvo’s infrastructure began in 2004 and was completed in December 2006. In August 2008 Provo city sold IProvo to a local company called Broadweave Networks. One year later Broadweave merged with Veracity Communications which became Veracity Networks. They are a locally owned company that provides telecommunications to both small and large businesses and residential homes alike. It is interesting that they chose the name “Veracity” for their business name since veracity is defined as “conformity to truth or fact” and “correctness or accuracy, as of the senses or of a scientific instrument...

...James Houghton, Chairman and CEO of Corning, has some tough decisions to make regarding the direction he wants Corning to take going forward. From the early 1900’s when Corning started the first research lab, there was no clear direction for the company. The company was successful but there was never a clear business plan laid out for Corning’s growth. It appeared that a number of decisions were made based on market trends, the economy and gut instinct. What James Houghton needs to do is lay out a plan for the future of Corning. Corning has already defined its goals, but how to achieve these goals is not clear. James Houghton has already been successful with his plan to “talk, listen and feel the atmosphere”, when it came to visiting the Corning sites. Corning also has seen significant success with the changes Houghton has implemented in the overall work environment. When Corning clearly defined the roles and responsibilities of its managers, morale improved and quality went up. If Corning can incorporate this same clear direction into their business plan, the management committee and all the other internal and external managers in their alliances would have a better understanding of what is expected of them and what they can do to continue to grow Corning Incorporated into a market leader in their four sectors of business. There are some great proposals that have been presented to the management committee. The management team needs to decide if Corning wants to strive...

Copper has been used in electric wiring since the invention of the electromagnet. Copper and its alloys are also used in buildings is the most important market for the copper industry. The inherent strength, hardness, and flexibility of copper building wire make it very easy to work with. Its flexibility makes it easy to join, while its hardness helps keep connection securely in place. There`s also another type of cabling you can use and its Fiber optic cabling which is becoming more in use in communication. Unlike copper fiber uses optical fiber elements which are typically individually coated with plastic layers and is contained in a protective tube suitable for the environment. Optical fibers are inherently very strong, but is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The strength of fiber as well with its change in time, are to be considered relative to the stress impose in today environment. Its benefits out way those of copper, fiber is relative to the stress imposed during handling, cabling, and installation for the set environment.

...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 for all Technology needs today. 1. Greater bandwidth Fiber provides far greater bandwidth than copper and has standardized performance up to 10 Gbps. While not currently a standard, these speeds could become a reality in future proposals and ratifications. Keep in mind that fiber speeds are dependent on the type of cable used. Single-mode cable offers far greater distance than either 62.5-...

...Charity Greene NT1310 Physical Networking Unit 1 Exercise 1 Local Exchange When you send an email from New York to Japan, that email,is sent from your home to the local exchange point over the access network. Once it is in the local exchange it is then sent to aggregating points in different cities and counties over the regional network. Then it is aggregated and transported over the long-haul network so that it reaches the launching point at the country shoreline where it is then sent over the ocean network to Japan. Once there, the email is sent back over the long-haul or regional network to the local exchange and then on to the individual receiving the email. This occurs using mostly fiber optics so the speeds at which all this takes is at the speed of light which is approximately 127,000 miler per second. To understand how to interface with the local exchange you must first understand the different networks that comprise it. The first network being the access network. The access network is the network that connects the individual user or business with the telecommunications system. This is made up of a series of fiber-optic and copper cabling and passive and active equipment that connects you to the local exchange. The central office at the local exhange contains the switching equipment to direct your telephone, data , video, etc. to where it needs to go. The access network is very important to the local exchange since its the part that reaches the end user, who...

...The first illusion was the Muller-Lyer Illusion. It consists of an arrow shape in which the arrowhead faces different directions. In the middle of the shape is another arrowhead that is supposed to divide the length of the arrow in half. The left-facing arrow illusion did little to affect my perception of the distance. However, I was consistently short on the right-facing arrow. The alignment of the arrow drastically affected my perception. I thought I was consistently dividing it in half, but the results showed otherwise. My average adjusted length was about 5.25% less than the correct length. The Muller-Lyer illusion works by altering our depth perception. Because most of us were brought up in square-cornered houses, the >-< shape appears closer and shorter than the shape. This is because the former looks like the edge of an exterior corner and the latter looks like the edge of an interior corner. This causes our mind to perceive the first shape as shorter than the second one, even though they are the same length. After learning about this phenomenon, my score improved from 5.25% to 3.25%. I still haven’t clearly grasped the concept and been able to perceive it correctly, but I did make a slight improvement. The Ponzo Illusion consists of a red and yellow bar whose heights must be matched. The two bars are placed in a room with the red bar much further back than the yellow bar. My perception was significantly affected by this illusion as I made the yellow bar about 49.5%...
