...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...

...Copper vs. Fiber Todd Gerger NT1310 Abstract In this paper we will be looking at the differences between Copper and Fiber optic cables. We will discuss the differences between the two and why many of the current networks in operation use fiber on the backbone between equipment and telecommunications rooms or enclosures. Copper vs. Fiber In the comparison between fiber and copper fiber, costs of the fiber cable has come down quite a bit. The cable itself has become easier to install as well since the invention of the flexible fiber which makes it easier to pull the cable through places. The flexible fiber has not become widely used vs. copper yet due to the need for the costs to come down for the connections, the NIC’s. the hub’s, routers and switches. Fiber Advantages The following advantages of fiber over other cabling systems are: (Oliviero 250) Immunity to electromagnetic interference (EMI), higher data rates, longer maximum distances, and better security. With copper cabling there is one common cabling problem they are susceptible to EMI. EMI is a stray electromagnetism that interferes with the signal. All electrical cables generate a magnetic field around their central axis. If you pass a metal conductor through a magnetic field an electrical field is generated in that conductor. When you place two cables next to one another EMI will cause cross-talk which is where signals from one cable is picked up on the other cable. Because fiber does not conduct electricity...

...Adam Wolfe 10/20/2012 NT1310 – Unit 4. Assignment 1 – Copper vs. Fiber The copper phone wire has very limited bandwidth. It was designed to provide 3,000Hz bandwidth, perfectly adequate for a voice signal. Fiber links offer over 1,000 times more bandwidth capacity and can be carried over 100 times the distance than copper can. The chart pictured here shows the specific advantages Fiber has over copper wiring in regards to bandwidth and distance. When it comes to LANs or premises cabling, a lot of controversy, a lot of "positioning" and a lot of misinformation are talked about by most people who speak on the topic of copper vs. fiber cabling. The wire most use for LANs is a lot younger than fiber optics. Fiber use is over 20 years old, but computer networks on unshielded-twisted-pair cable (UTP) have only been around about 15 years. In that time, UTP has gone through at least 5 generations, each time to keep up with the incrementing bandwidth requisites of LANs; the ever evolving technology of LAN wire is hardly the “telephone wire” that the majority think of it as. Below is a chart showing the LANs growth in capacity LAN | Bandwidth | Ethernet | 10 Mb/s | FDDI | 100 Mb/s | Fast Ethernet | 100 Mb/s | ATM | 55, 155 Mb/s | Gigabit Ethernet | 1,000 Mb/s (1 gigabit/s) | 10 Gigabit Ethernet | 10 Gb/s | But still, even with all the efforts that copper cabling manufactures have made to stay relevant in todays LAN structuring, installation is a problem...

...Unit 4 Assignment 1 Copper vs. Fiber Pape The two most common and widely used cabling types today for the means of communication all over the world are copper and fiber. They both do the same thing, transmit information from point A to point B but both have their strengths and weaknesses and therefore, a person installing cabling may be reluctant to choose one over the other. Copper cabling is less expensive to install. Copper wiring is flexible when installing so incase a technician has to bend it around a wall or at a certain angle to reach it to an end point, the cable can handle it. Also equipment to support copper wiring is relatively inexpensive to run. The weaknesses to copper wiring would be that it is susceptible to electromagnetic inference (EMI) from outside forces and also has a higher rate of corrosion over time by oxidation. Fiber optic cabling is a more expensive option for communications. Fiber optic cabling is immune to EMI and other noise interferences and therefore the chance of signal loss is greatly reduced. One drawback on this type of cabling is that just like its copper; fiber optic cabling is very durable and tough making it harder to work with when it comes to installing it. A technician will have to be very well trained in handling it to get the most out of it for the customer. But fiber optic cabling has a much higher bandwidth over copper so it can handle much more traffic as well as at higher speeds than copper wiring. In the real world, one...

...Cable vs. Fiber optical wiring is becoming a discussion that drives industries and businesses. It is a very important to understand the differences between the two types of cables and their abilities. The capabilities of these types of wires, prices, availability, and future uses are important factors to take into consideration when designing a layout for a building. Some other important variables to consider are how many people are trained to install the cabling and how durable that cabling is and how it can withstand long term use. Copper cabling is the widely used standard of today. It has been used as a communications line since the first telegraphs. Over the years it has developed into thin multi lined cables that can send an abundant amount of data. Since it has been around so long it is widely understood and taught to professionals as well as your average Joe. Category 5e and 6 are both capable of sending signal speeds much faster than we are able to produce at bandwidths that we haven’t reached yet. So at least for the near future copper cabling can still sustain Moore’s law. This law states that technology will double in capacity and for half of the price every two years. While copper is inexpensive now it becomes more expensive with its wide use. Also its abundance will degrade over time as it is used commercially worldwide. Some more of the flaws that are involved with copper are EMI, unnoticeable tampering, and potential. Electromagnetic interference can cause signal...

...dedicated to information technology or networking on the staff. Also, there are twenty Windows peer-to-peer client computers all connected via coax cabling. The president indicates that the company plans to double in size over the next two years, but she is weary of drastically changing the computing environment. My job as a recently hired consultant is to suggest and give a breakdown of a new 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...

...Unit 4. Assignment 1. Copper vs. Fiber Paper Copper (Ethernet) Cable * Ethernet cables are vulnerable to electromagnetic interference because they work through electrical signals. * Due to the way in which data is transmitted across Ethernet copper cabling, it is vulnerable to being intercepted. * Ethernet offers less bandwidth. Ethernet can provide data transfer speeds of up to 1000Mbps, but through the use of Cat 6 cables it can support data transfer rates of up to 10Gbps. * There is always electricity present in Ethernet cables. * Copper cabling strands are thicker than optical fiber strands, so less wires can be bundled in a 22 gauge copper cable than in a 22 gauge optical fiber cable. Optical Fiber Cable * Fiber optic cables are ideal for high voltage locations, in buildings prone to lightning strikes, and locations where explosive fumes are present. Because optical fiber cables work through the transmission of light, interference from electronic devices isn’t a concern. * Information sent via fiber optic cables is much more difficult to intercept because light can’t be read in the same way signals sent via copper cabling can be. * A single optical fiber strand has been shown to transmit data at a rate of 100 terabits per second. Optical fiber transmits data faster than copper Ethernet cable. * Unlike Ethernet cable, optical fiber cable is non-flammable because it does not use electricity. | Optical fiber Copper wire Safety ✔ ✖ Weight...

...Copper vs Fiber These two forms of cabling are mostly used in the world today and it is up to the location to decide which cable is best. They both have their strengths and weakness; I am going to shed some light on these two cables. Copper gives you the ability to power phones, surveillance cameras, Wireless Access Points, and many other devices right through the networking cable, meaning that you don’t have to schedule an appointment with an electrician in to run power to your surveillance cameras to power them. To make it better copper is cheap, flexible and easy to run, most computer currently has a copper NIC in it. Category 6A Cable is classified by the Telecommunications Industry Association (TIA) to handle a bandwidth up to 600 MHz over 100 meters, which possibly, could carry around 18,000 calls at the same time. The maximum allowed industry standard of attenuation for Category 6A cable over 100 meters at 100 MHz is 20.9 dB which is a 94% loss in signal strength. Fiber provides far greater bandwidth than copper and has standardized performance up to 10 Gbps, the fiber optic signal is made of light, very little signal loss occurs during transmission, and data can move at higher speeds and greater distances. Fiber distances can range from 300 meters (984.2 ft.) to 40 kilometers (24.8 mi.), depending on the style of cable, wavelength, and network. All data is safe with fiber cable, because it doesn’t radiate signals and is extremely difficult to tap, if the cable...
