...Unit 5 Assignment 1 Cabling Factors and Tolls Discussion Flexibility What type of install is the cable going into? Is everything in a fixed position? If you have an install where items are moved around without being disconnected, using highly flexible cable is necessary. Cables in these scenarios need to be flexible to meet those demands of mobility, and also for the life of the wire so that it does not crack, break, fray or short. We had a job at a university where we moved flat panels on a track system to create different screen sizes, and for that we had to make sure the cable would meet the demand. Capacitance Cat 6 is not always better than Cat 5. If a video extender is made for Cat 5e, using Cat 6 may cause you a problem. The electrical properties are different, and the circuitry inside may not be able to reconcile the increased capacitance. You should confirm with the manufacturer before making a substitute in a Category cable. Jacket What type of jacket does your cable need? You have plenum, riser, PVC/non-plenum and direct burial. Plenum cable is often required in commercial work, especially in buildings where there are open-air returns; it is essential to meeting code. Integrators will often use riser grade at the riser, and then transfer to plenum in the plenum space. This saves some cost, but I recommend you second-guess saving that few cents per foot in most cases. The chances of mixing up a box of cable and pulling riser in the plenum space may increase...

...Physical Networking Unit 2 Assignment 1. The American National Standards Institute is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide. For example, standards ensure that people who own cameras can find the film they need for that camera anywhere around the globe. ANSI accredits standards that are developed by representatives of standards developing organizations, government agencies, consumer groups, companies, and others. These standards ensure that the characteristics and performance of products are consistent, that people use the same definitions and terms, and that products are tested the same way. ANSI also accredits organizations that carry out product or personnel certification in accordance with requirements defined in international standards. 2.

...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...

...Carlyle Brown Network Protocols and Standards Week 3 Homework 1. When was the first major standard describing a structured cabling system released? c. 1995 2. Why is balance an issue in UTP cables, and what is TCL? i. The balance or symmetry of the signal over the wire pairs helps minimize unwanted leakage of the signal. ii. TCL - Transverse Conversion Loss - The TCL measurement is obtained by applying a common-mode signal to the input and measuring the differential signal level on the output. a. TCL is sometimes called LCL (Longitudinal Conversion Loss). The ELTCLT value (expressed in dB) is the difference between the TCTL and the differential mode insertion loss of the pair being measured. TCTL is the loss from a balanced signal at the near-end to the unbalanced signal at the far end. Section 2-2 1.

...Fritz Dorcelus _ Physical Networking Cable Structure Week 3 assignment 1-What are the most common cables used today? Unshielded twisted-pair (UTP), shielded or screened twisted-pair (STP or ScTP), coaxial, and fiber-optic (FO) 2. Simply installing STP cabling does not guarantee that you will improve a cable’s immunity EMI or reduce the emissions from the cable. What are several critical conditions must be satisfied to achieve good shield performance? * The shield must be electrically continuous along the whole link. * All components in the link must be shielded. No UTP patch cords can be used. * The shield must fully enclose the pair, and the overall shield must fully enclose the core. Any gap in the shield covering is a source of EMI leakage. * The shield must be grounded at both ends of the link, and the building grounding system must conform to grounding standards (such as J-STD-607-A). 3. What are the distinct advantages of fiber optic? • Transmission distances are much greater than with copper cable. • Bandwidth is dramatically higher than with copper. • Fiber optic is not susceptible to outside EMI or crosstalk interference, nor does it generate EMI or crosstalk. • Fiber-optic cable is much more secure than copper cable because it is extremely difficult to monitor, “eavesdrop on,” or tap a fiber cable. 4. Cable bandwidth is a function of three interrelated, major elements. What are these major elements? Distance, Frequency, and Signal-level-to-noise-level...

...LAN Topologies It 240 Week 2 Assignment: LAN Topologies IT/240 Week 2 Assignment 1. Case Project 2-1 With a network of 50 computers I will use the Ring Topology to upgrade this network. With this type of topology all the devices are connecting in a loop form and the information travels in one direction, thus avoiding collisions. Here the cabling doesn’t terminate, it continually goes from one device to another till it gets back to the original device. It is also easier to manage the network since all the information is passed around the ring in the same direction. 2. Case project 2-2 With that many computer and four servers, I will use an Extended Star Topology. As pointed out in the case project that there are a few switches available here, I will use a central switch and connect the rest of the available switches to it and connect the 200 PC’s to those switches. Switches are good for determining each individual packet’s destination and ensuring that they are delivered to the right device. Note- Even though they might have two different uses in some cases, the hubs in my diagram represent the switches.
