What industry standards body and standards series numbers do you need to reference for Ethernet applications and cabling?
a. The Commercial Building Telecommunications Cabling Standard, known as ANSI/TIA/EIA-568-C.
b. The IEEE maintains the industry standards for Ethernet protocols, which is part of the 802.3 series of standards. There is an increased need for speed these days and network technology designers are planning to support data rates of up to 100Gbps.
2. What are the different types of Category 6 cable and what should be recommended for this network?
a. 10Gbps @ 100 Meters – There are two types of Category 6 cable, regular Category 6, and Category 6A (or Augmented Category 6). It would be my recommendation to use 6A or Category 7. Since we have to support 10Gbps over a maximum of 100 meters, I would recommend using Category 6A, or Category 7 cabling.
3. What cable would you recommend to offer the best shielding performance?
a. Full of stray EMI, UTP not an option, and customer wants to ensure capability to operate at 10GBase-T.
i. I could recommend a Screened Twisted-Pair Cable or Screened Shielded Twisted-Pair Cable.
4. What type of cable would you use for
a. Horizontal Spaces – Plenum cables. Solid Conductor Wire.
b. Vertical Spaces – You should use riser-rated cabling in vertical spaces or where flexibility is important. Stranded-conductor wire.
5. What would you look for in trying to find fault if you had the following failures:
a. NEXT and FEXT problems in 1Gbps links – Make sure that the twists in the cables have not been undone and check the coupling. Also, you can reduce FEXT by using rectangular-shape resonators. Another solution that the book mentions is to use shorter cables.
b. Difficulty meeting 10Gbps performance requirements – Check electromagnetic interference by using a device that can detect the amount of interference. You can move the cables away from the source of the interference. Other solutions include using cables that are properly shielded or using fiber optic cable.…...

Cabling and Fiber Optic

...of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear image of the scenery surrounding the pool. Throw a rock into the pool, and the water is perturbed to form waves, which disrupt the reflection by scattering the reflected light rays in all directions. Signal degradation can occur in many ways. Signal degradation can occur if you are trying to communicate over vast distance that the system was not designed for. An example of this is, if the equipment or cable becomes damaged or the antenna becomes blocked. References Oliviero, A., & Woodward, B. (2011).

Unit 5 Cabling Factors

...4/14/2014 Unit 5. Assignment 1: Cabling Factors and Tools Discussion Three factors that need to be considered is being fire protected, water proof, and shock protection. Being fire protected, just in case a fire occurs, the wiring would be protected by a casing around the actual wires which in cause wouldn’t melt the casing and destroy the wires. Since the data room is usually in the basement of companies, if a flood occurs, there are wires that are protected by a casing that would not let water intrude into the casing. For shock protection, there is always a chance for a shortage to happen. Wiring and a lot of electricity used. For example, if there is a storm going on and lightning hits a generator and shorts everything out, it would not fry the wiring if they are protected from the shock. The two most important considerations to take into account when either pre-wiring a house or wiring after the house is complete, are the routing of the cable and the quality of the wire used. These two points are often overlooked and the decision to wire the house at all often comes as an afterthought, when most if not all of the interior of the structure has been completed. Some tools that would be useful to use are cable cutters, hole cutting tools, wire strippers, punch down tools, RJ45 connector crimp kits, pliers and cutters, label makers and electrical tape. The makeshift tool that we would use is a staple gun....

Copper Cabling vs. Fiber Optic Cabling

...Copper Cabling vs. Fiber Optic cabling The most commonly used copper cables are Cat5e and Cat6. Cat5e cabling is able to support applications requiring bandwidth up to 100MHz and is also offered in a shielded version to prevent interference. Cat6 cabling supports applications requiring bandwidth up to 250MHz and is also available in a shielded version. Also Cat6 cabling is designed to support 1000Base-T (Gigabit Ethernet) (Oliviero, 2010). However, as cost efficient as copper cabling is compared to fiber optics, the maximum horizontal distance is only 90meters (Oliviero, 2010). So if you have a large building or organization you will need to account for the cost of additional hardware like patch panels etc. Fiber optic cables have become very popular over the last ten years because they can be run for longer distances (up to 46.6 miles) and support a higher bandwidth than copper cabling. Fiber optic cabling uses digital light pulses instead of electrical voltage transitions (Oliviero, 2010). This makes it much faster than copper cabling because light is immune to interference, can be modulated to higher frequencies, and travels almost instantaneously to its destination (Oliviero, 2010). Another advantage to fiber optics over copper cabling is security. Copper cabling is susceptible to eavesdropping through taps. Fiber optics are immune to this because they are not electromagnetic. There are three main types of fiber optic cabling, outdoors, indoors, and universal. In......

...applications and cabling? A # 1) The IEEE sustains the industry standards for Ethernet applications and cabling. This is a segment of the 802.3 series of standards and includes applications such as 1000Base-T, 1000Base-SX, 10GBase-T, 10GBase-SR. I found the answer on page 8 in Cabling: The Complete Guide to Copper and Fiber-Optic Networking 4th Edition book. Q # 2) What are the different types of Category 6 cable and what should be recommended for this network? A # 2) Only two different types of 6 cables Category 6, 250 MHZ and Category 6A, 500 MHZ. I would recommend for this network the Category 6A because it has a higher MHZ and as well the network intended to use 10 GB Ethernet with a bandwidth support of 500 MHZ is better than 250MHZ support. The reason I recommend this because of the information on page 8, 12, 17, and 35 in the Cabling: The Complete Guide To Copper and Fiber-Optic networking 4th Edition Book. Q # 3) What Cable would you recommend to offer the best shielding performance? A # 3) I would recommend the S/STP cabling, also known as screened fully shielded twisted – pair (S/FTP), Contains four individually shielded pairs of 24,AWG, 100 ohm wire surrounded by outer metal shielding covering the entire group of shielded copper pairs. This type of cabling offers the best protection from interference from external sources, and also eliminates alien crosstalk, allowing the greatest potential for higher speeds.

... shorts in networking hardware, systems that run too hot and placed in tight areas with no ventilation just some examples. Some aspects of proper design are having a detailed plan of how the installation will proceed, you should know the scope of the project, and i.e.…how many cable runs you have what connections need to be made. Your design should also be made available to all people involved with the installation. As well as contain a blueprint of how the cables will be installed. Tools that will be useful in your installation will be, Wire cutters, crimpers, pen and paper, fish tape, pull string, two way radio, labeling materials, punch down tool, toning tools, basic hand tools. I know I have used off the book tools to install cabling. One of the tools I used and it actually stays in the wall is a small plastic funnel. It actually keeps the cable from bending when not going through the back side of the wall. When you cut your spot out where you’re placing your connection box place a small funnel with the cone side in and pull the cable through that actually allows the cable to make a gentle right or left turn rather than being pulled and causing a sharp corner on the cable itself....

Advans of Copper Cabling

...There are many advantages to using copper cabling. Its more durable, cheaper, and easy to install. Copper cable comes in three different types, TP-Twisted Pair, UTP-Unsheilded Twisted Pair, and Coaxial. Among these three they have their own separate intities. There is thinnet and thicknet for the coaxial and shielded and unshielded for the twisted pair. All these different cables have different transmission rates and special features. These features are coaxial has electronic support component that is less expensive than twisted pair. But the twisted pair is the same as telephone wire and most of the time is installed during the building of the building. The use of thinnet coaxial is medium to large sites with high security needs. Thicknet is used as a backbone to connect the thinnet networks. And TP is used for small sites on a budget that are the size of a token ring. On the other hand for the company that has the money to spend fiber optic cable is the way to go. Its faster in speed not as easy to work with but works a lot longer and transmission is a lot further. Which means have the cable can be used to go twice the distance. Fiber optic comes in two types MMF-Multimode Fiber and SMF-Singlemode fiber. This type of cable is not susceptible to EMI like coaxial or twisted pair. Fiber optics supports voice, data, and video. For the company that has the biggest budget and want the best in security, speed, and integrity fiber optics is the best cable to go......

...The IEEE (Institute of Electrical and Electronics Engineers) maintains the industry standards for Ethernet protocols. The 802.3 series includes Ethernet applications and cabling. The different types of category 6 cable includes CAT6, CAT6A, and CAT6E, although 6E is not an industry recognized standard. I would recommend CAT6A for the possible 10GBASE-T upgrade in the future because it has improved alien crosstalk characteristics when compared to regular CAT6. Unless you decided to go with fiber, you should use STP CAT 6a or CAT7 for a 10gbase-t network, although there were quite a few articles online arguing that shielded cable is unnecessary after going to cat6a or 7 due to higher frequencies that these cable can utilize. The horizontal spaces should use fire retardant plenum cable since it is also used for HVAC. While it might also be prudent to use fire retardant riser cabling for the vertical shafts as well, however if fire stops are placed in the risers you could get away with using regular UTP as well in some places if cost was an issue. The NEXT and FEXT problems could have something to do with having a cable with too many twists, with NEXT the problem would be at the end of the cable where the signal originates, and with FEXT it would be at the opposite end. As the signal rate increases alien crosstalk become more and more of an issue. If it is too much of an issue your best bet might be to upgrade to fiber....
