The Benefits of Twisted Pair Cable 2
Abstract
I have been recently hired by a Network Consulting Firm (NCF) and my fist task as a consultant will be to work with Ocper, Inc. Upon arrival at Ocper, I learn from the president that there is no one dedicated to information technology or networking on the staff and there are 20 Windows peer-to-peer client computers connected via coax cable. The president also addresses her concerns for growth. She feels that the company will double in size over the next two years, but does not want a drastic overhaul. For this assignment I will hit 4 main topics. First I will describe what changes I would suggest for the current network type and explain why I am doing it. Second, I will describe why I would recommend upgrading to twisted pair cable from coax cable for all current and new client computers on the network. Third, I will discuss the possibility of implementing fiber optic cable in to the network. Finally, I will display research costs and analysis to facilitate an upgrade on the network. As above mentioned, the current network is 20 Windows peer-to-peer client computers utilizing the bus topology. Also important to note is the fact this company lacks an employee with an IT background, therefore they have been inclined to set up a simple peer-to-peer network due to its ease of configuration. Unfortunately for Ocper, if they want to effectively expand, they will need to change this network type, because a peer-to-peer network is not flexible. As the network grows, adding or changing important elements of the network may grow cumbersome. Additionally, the peer-to-peer network for this client is dire need of a centralized resource. I would highly recommend that this company switch from peer-to-peer to a Local Area Network (LAN) network immediately. As far as growth is concerned the client/server would not facilitate the same amount of growth that a LAN could. On the other side of the coin a Metropolitan Area

Network (MAN) or a Wide Area Network (WAN) are both too big for a company that is not willing to make drastic changes. The client currently has 20 computers and plans on expanding to double in 2 years. Therefore these 40 computers could be broken up in to several peer-to-peer networks connected to several switches that connect to the router. All printers, faxes, and telephones could also be connected to other switches that would connect to the above mentioned router. To keep it simple and minimize throughput on the bandwidth I would recommend a maximum of 5 computers to each switch. Another hardware option to consider is the type of cabling. When it comes to cabling we have 3 main choices, Coax, Twisted pair, and Fiber optic. Ocper already has some coax cable available which can be implemented in to the new network, but it is more expensive then twisted pair and cannot pass as much data as higher end twisted pair or fiber optic wires can. Another thing to consider for twisted pair is its physical aspects; much lighter, wires are more flexible, easier to repair breaks in the line (splicing). Fiber optics also have similar physical attributes, however with higher quality comes a higher price tag. I would suggest connecting all current and new client computers using twisted pair instead of staying with the current coax cable wiring structure, because if one cable goes down the whole network will not go down, it can pass data at a faster rate, its lighter, and it cost less. Fiber optic wire could also do all of that and run faster with an increase to the price. It is very important to understand the scope of the client. If money were not an issue, I would recommend upgrading to fiber optic for four main reasons. First, it is immune to electromagnetic interference. Second, it is the most secure signal
The Benefits of Twisted Pair Cable 4 to send. Third, they are easy to install. Fourth fiber optic wire has a large capacity to carry high speed data signals over a long distance without a repeater using single-mode or multi-mode. While in the real world price is a concern, so I would delegate the fiber to the router and switches. From the switches to the client computers I would utilize twisted pair cable starting with CATV for most nodes and VIP would utilize a higher quality twisted pair cable.
After researching I would recommend the following products: NETGEAR 5 Port 10/100 Business-Class Desktop Switch (with life time warranty $25.99), Cisco CISCO2911-SEC/K9 2911 Security Bundle with Sec Lic ($2,298.23), 1000ft fiber optic cable spool ($267.99), CAT V cable 1000 ft spool ($85.00), and CAT 7 100 ft spool ($61.00). The total of parts equaling $2816.18 and 25.99 per switch needed for additional client computers.
The President of Ocper can have her cake and eat it with this easy upgrade that allows the company to expand without having to drastically change the computing environment. First, I have described what changes I would suggest for the current network type and explained why I was doing it. Second, I have described why I recommended upgrading to twisted pair cable from coax cable for all current and new client computers on the network. Third, I have discussed the possibility of implementing fiber optic cable in to the new network. Finally, I have displayed research costs and analysis to facilitate the upgrade on the network.

The Benefits of Twisted Pair Cable

...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......

...THE BENEFITS OF TWISTED PAIR CABLE Recommended Changes and Benefits As I am a consultant for NCF, the Networking Consultant Firm and my first assignment are at Ocper, Inc. We will first study to their current networking and current technology that they are using. First, they have use coax cable to connect 20 windows peer to peer computers. The president had told me that he expect his company to be expand and double in size, in the next two years. What NCF will recommend is to take a closer look at benefit of twisted pair cable. Since the business now needs to connect 20 computers, I would explain how twisted pair cable will help them. Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are 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. They need to be more understand their current situation so; it could help them to get the highest performance from it. The twisted pair cable come with in two varieties; shielded and unshielded twisted pair. For this case, I would choose the unshielded twisted pair to be the solution because this cable is the least expensive cable, there are pro and cons, it may be susceptible to radio and electrical frequency interference (it should not be too close to electric motors,......

...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.......

...Benefits of Twisted Pair Cable Gregory M. Dowell CIS 175 Professor Blanson November 3, 2013 Benefits of Twisted Pair Cable Ocper, Inc. is a company that currently has twenty employees connected in a peer-to-peer network. Over the next two years they are looking to double in size and are looking for a solution to their computer networking needs but are weary of any drastic changes. Currently all of their computers are connected using coaxial cable. Through this paper I will show the benefits of changing their network configuration, as well as replacing the coaxial cable with twisted pair or possibly fiber optic cable. My fist suggestion is to reconfigure their network from peer-to-peer to a client/server network in a star configuration. By doing so, there will be a central computer used as a server that would facilitate communications and resource sharing between the other computers on the network. With this server clients will be able to share data, data storage space, and devices such as printers. The users will still be able run applications and save data to their own computer, but will also have the option to save it to the server (Dean, 2009). Saving the data to the server will enable better security of the data since backups to the system can be scheduled every night. In addition, each client can be authorized only the access to the applications they need. In the peer-to-peer configuration each computer can communicate with each other......

...early stages of your company, although by using this kind of network, important data can be snatched pretty easily by someone that intends to sabotage your company. This can be easily stopped by implementing a client/server network. A client/server network will safeguard all your data from unwanted eyes. The network administrator can also set security measures such as giving certain people access to certain files. I would also like to suggest changing the wiring structure of your network. I see that you are currently using coaxial cable in your network. Though coaxial cables have their advantages the disadvantages are pretty hefty. Listed below are some disadvantages that could cause your business some trouble. * Problems with the deployment architecture—The bus topology in which coax is deployed is susceptible to congestion, noise, and security risks. * Bidirectional upgrade required—In countries that have a history of cable TV, the cable systems were designed for broadcasting, not for interactive communications. Before they can offer to the subscriber any form of two-way services, those networks have to be upgraded to bidirectional systems. * Great noise—The return path has some noise problems, and the end equipment requires added intelligence to take care of error control. * High installation costs—Installation costs in the local environment are high. * Susceptible to damage from lightning...

...cat5e cables for the network. The star network has the advantage of adding nodes or work stations as the business grows. When it comes to monitoring and troubleshooting the system, it is made easier due to the centralization of the hub/switches. The reliability of a star network is another advantage to the company. If one node or workstation fails in the network the rest of the network is affected by the failure. While the star topology has many advantages it also has some disadvantages. The star utilizes a central location for the hub/switch so if it fails the entire system is down. By adding a backup hub/switch this issue can be minimized in the event of the main hub/switch failure. The initial cost of equipment can also be a concern. The cost of the hub/switch will run about $750 to $1800 for each hub/switch, if you add a backup that price will be $1500 to $3600. Depending on the work station NIC cards you may need to upgrade to new cards that accept the Cat 5e cable. I would recommend installing Cat 5e or Cat 6 (speeds up to 1000 Mbps, 1 gigabit per second Gbps) twisted pair cables rather than using the coaxial cable. The twisted-pair cable is designed for telephone communications and modern Ethernet networks. The pairs of wires are twisted to give protection against crosstalk; crosstalk is interference of noise generated by adjacent pairs. Just like any electrical wire a magnetic field is produced when current flows through it. By twisting the wires together in pairs......

...few advantages over your current peer-to-peer network which include having user logon account and passwords in one centralized location, access to multiple shared resources, problems on the network can be monitored, diagnosed, and fixed from one location and faster response time because servers are optimized to handle heavy processing loads (Dean, Network+ Guide to Networking, 2009). I would suggest that we upgrade from the current coax cable, which has a data speed ranging from 10 MB per second up to 350 MB per second, to a twisted pair cable that has a data speed of up to 1 GB per second (Gates, 2011). Twisted pair cable consists of a pair of insulated wires that are twisted together. The twisting of the cables helps to reduce noise pickup from outside sources. Since you plan to expand your company over the next two years, using the twisted pair cable will make it much easier to add the additional workspaces. If we set up the network to accommodate the extra workstations you anticipate, when the time comes you will just need to plug the cables into the designated switches and be...

...system. Suggestion of Changes In Terms of the Current Network Type/Structure with the Benefits. I would advise the president to replace the current network setup to twisted pair cable. Coaxial cable carries high frequency signals along a single center conductor, whereas, twisted pair cable improves its electrical characteristics at a lower voice frequency and prevents signals from crossing into adjacent wires. It also allows the signal to travel longer distances. Reasoning for Suggesting Connecting All Current and New Client Computers Using Twisted Pair Cable Instead of Staying With the Current Coax Wiring Structure. Twisting two insulated wires together improves their electrical characteristics at a lower voice frequency and prevents signals from crossing into adjacent wires. It also allows the signal to travel longer distances. Coaxial cables carry high-frequency signals along a single-center conductor surrounded by a foil or braided copper shield. Coaxial cable has less loss than twisted pair, and the shield protects the signal from interference. There are two types of twisted pair cable, shield and unshielded. Unshielded twisted pair, or UTP is so closely identified with Ethernet implementations that it is often called “Ethernet cable.” This form of cable can contain any number of wires, but the most common form used for networks contains eight wires, configured as four pairs, with...

...performance with new tecnology. • New Technology- is there new technology available that can better support the companies needs and growth over the next 20 yrs. • Pros and Cons- what are the benefits of upgrading to a new topology and the negatives of upgrading. • Future exspansion- can the existing coaxial infratructure support the companies growth over the next 20 yrs. • Cost- how much will, it cost the company for initial upgrade and future growth. These are our recommendations: Your company currently has 20 workstations connected with coaxial cabling. The company wants to expand and double its size in the next 20 years. We recommend that you upgrade your cabling at the minimum to a twisted pair CAT5 or CAT6, preferably CAT6. Coaxial cable for network connections is obsolete and does not provide the performance or scalability to support a growing company. All though twisted pair cabling is a suitable choice for your company, we would also like for you to consider the possibility of using Fiber Optic cabling. Fiber Optic cabling would be our preferred choice for your company. The benefits of twisted pair cabling are that they reduce cross talk on multi pair cables. Twisted pair cables transfer balanced differential signals more efficiently than coaxial cable. Twisted pair cabling is easy to install, improves...

Twisted Pair

...The Benefits of Twisted Pair The Benefits of Twisted Pair The current topology appears to be a bus topology. Everything is connected via coaxial cable and is referred to as passive, meaning that each computer on the network “listens” for data to pass by with its name. While this type of topology will suffice for small networks, it is not ideal for the current network at Ocper, inc. Another downside of the current topology is lag. While the network is small you may not notice the lag, or just assume the network is supposed to run this slow. Using coaxial cable as a network data path limits the amount of bandwidth available as well as the ability for two-way data flow. My recommendation would be to convert to twisted pair cabling. The twisted pair cable will allow you a larger bandwidth which in turn allows more computers to send more data across the network. Twisted pair will also allow two-way data flow, allowing for data to pass back and forth more effectively by “sharing” the bandwidth. For these reasons, twisted pair will allow you to transfer vital information back and forth across the network much more quickly, making the customer wait less. I would also recommend changing the topology to a star-wired Bus. A star-wired bus will allow you to isolate segments of your network and span it over greater distances. Isolating a segment of the network will allow you to place different security......

Transmission: Refers to either the process of transmitting or the progress of signals after they have been transmitted. * Analog and Digital Signaling: * On a data network, information can be transmitted via one of two signaling methods, analog or digital. * Voltage: the strength of an electrical signal * Analog: * One benefit to analog signals is that, because they are more variable than digital signals, they can convey greater subtleties with less energy. * One drawback to analog signals is that their voltage is varied and imprecise. Thus, analog transmission is more susceptible to transmission flaws such as noise, or any type of interference that may degrade a signal, than digital signals. * Digital: Composed of pulses of precise, positive voltages and zero voltages. A pulse of positive voltage represents a 1, a pulse of zero voltage represents a 0. * Continuous * Amplitude: Waves amplitude is a measure of its strength at any given point in time. The amplitude is the height of the wave at any point in time. * for example, the wave has an amplitude of 5 volts at .25 seconds, an amplitude of 0 volts at .5 seconds, and an amplitude of -5 volts at .75 seconds. * Frequency: the number of times that a waves amplitude cycles from its starting point, through its highest amplitude and its...

...disadvantage is that only one computer can use the circuit at a time. When one computer is sending or receiving data, all others must wait. The advantage of multipoint circuits is that they reduce the amount of cable required and typically use the available communication circuit more efficiently. Imagine the number of circuits that would be required if the network in Figure 3.2 was designed with separate point-to-point circuits. For this reason, multipoint configurations are cheaper than point-to-point circuits. Thus, multipoint circuits typically are used when each computer does not need to continuously use the entire capacity of the circuit or when building point-to-point circuits is too expensive. Wireless circuits are almost always multipoint circuits because multiple computers use the same radio frequencies and must take turns transmitting. Question 3: Describe three types of guided media. Twisted-Pair Cable (Fitzgerald & Dennis, 2009): One of the most commonly used types of guided media is twisted-pair cable, insulated pairs of wires that can be packed quite close together (Figure 3.9). The wires usually are twisted to minimize the electromagnetic interference between one pair and any other pair in the bundle. Coaxial Cable (Fitzgerald & Dennis, 2009): Coaxial cable has a copper core (the inner conductor) with an outer cylindrical shell for insulation. The outer shield, just under the shell, is the second conductor. Because they have additional shielding......

...July 28, 2013 The Benefits of Twisted Pair Cable Computer networking is the basis of the Internet and most all businesses globally. Methods of communication are available to us today which would not be possible without computer networks. Networks increase productivity by allowing computers to and users to simultaneously share data and resources. With a network setup Information is centralized, and repetition of information is avoided because it is shared throughout the network. Networks enable business functions to be completed faster and more precisely. Networks also allow the possibility of expanding as the business grows. Ocper, Inc. currently houses 20 windows peer to peer client computers with the expectation of doubling in size within the next two years. Although a peer to peer network is inexpensive to set-up and allows for file and printer sharing without special software, there are limitations and disadvantages to this setup. In a peer to peer setup, each client is dependent upon the knowledge of each user, and if any user were to shut down at any point, every other user would lose access to any resources that machine shared. The security of the network is less than desirable. Managing all the clients on a peer to peer network can be quite time consuming considering each client would have to be physically visited in order to do maintenance or updates. In order to make the network more secure and also allow for sharing of resources even when a user logs......

...232. Unshielded Twisted Pair – A pair of copper wires twisted together with no electromagnetic shielding around them. Each wire pair is twisted many times per foot (higher grade UTP cable can have more than 20 twists per foot). The twists serve to cancel out the electromagnetic interference that the transmission of electrical signal though the pairs generates. Shielded Twisted Pair – A type of twisted-pair cable in which the pairs are enclosed in an outer braided shield, although individual pairs may also be shielded. The pairs in STP cable have an individual shield, and the individual shielded cables are wrapped in an overall shield. The advantage of STP cable over UTP cable is that there is less attenuation at higher frequencies and is less susceptible to EMI. Fiber-Optic Cable – Fiber-optic cable uses a strand of glass or plastic to transmit data signals using light; the data is carries in light pulses. Unlike UTP/STP, the transmission techniques are not electrical in nature. Plastic-core is easier to install than traditional glass core, but plastic cannot carry data as far as glass. Dark Fiber – When telecommunication companies first run the fiber-optic cable, they don’t run the exact number of strands that they need. They install two to three times as much as they require. The spare strands of fiber are called dark fiber because they are not in use. The Dark Fiber usually lease out these lines to other companies. Coaxial Cable – Also called coax cable. When it......
