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

This is an Executive Summary Plan for our new building for which construction begins in exactly six weeks. My name is David Pierce and I will be the Project manager for the design and installation of our new cable network for that building. I am excited to be a part of the project and look forward to working with each and every one of you during this exciting time of growth for our company. When considering the capacity if this project I ask you to consider all ideas or changes you see as plausible

align and connect optical fibers. Mechanical splicing methods may involve either passive or active core alignment. Active core alignment produces a lower loss splice than passive alignment. However, passive core alignment methods can produce mechanical splices with acceptable loss measurements even with single mode fibers. In the strictest sense, a mechanical splice is a permanent connection made between two optical fibers. Mechanical splices hold the two optical fibers in alignment for an indefinite

An optical fiber or optical fibre is a thin, flexible, transparent fiber that acts as a waveguide, or "light pipe", to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead

Horizontal Cable - The wiring/cabling between the telecommunications outlet/connector and the horizontal cross-connect. Backbone Cable - cabling is the inter-building and intrabuilding cable connections in structured cabling between entrance facilities Patch Cords - an insulated cord with a plug at each end, for use with a patch panel Connectors - a device for keeping two parts of an electric circuit in contact Conduit - a protective cover, tube or piping system for electric cables Racks -

stimulated emission of radiation. The laser produces a coherent source of light with a narrow beam and a narrow spectral bandwidth (about 2cm). Lasers in fiber optics are usually solid-state semiconductor types. Lasers are used to provide the high-powered, tightly controlled light wave lengths necessary for high-speed, long-distance optical fiber transmissions. 4. Output Pattern: A setting that selects the output pattern for comparison outputs. This enables outputs for changes in levels rather

A passive optical network (PON) is a system that brings optical fiber cabling and signals all or most of the way to the end user. Depending on where the PON terminates, the system can be described as fiber-to-the-curb (FTTC), fiber-to-the-building (FTTB), or fiber-to-the-home (FTTH). All PON systems have essentially the same theoretical capacity at the optical level. The limits on upstream and downstream bandwidth are set by the electrical overlay, the protocol used to allocate the capacity and manage

1. Plenum and coaxial cable are not common cables used today. 2. A decibel is the unit of measurement that is a tenfold logarithmic ratio of power output to power input. 3. Frequency increases does not contribute to attenuation. 4. Mutual crosstalk is not a type of crosstalk. 5. The Federal Communications Commission (FCC) is part of the US government. 6. The National Fire Protection Association (NFPA) is responsible for the development and publication of the National Electric

calories. The fruit is made of soft, easily digestible flesh (bulbs) made up of simple sugars like fructose and sucrose that when eaten replenishes energy and revitalizes the body instantly. Jackfruit is rich in dietary fiber, which makes it a good bulk laxative. The fiber content helps protect the colon mucous membrane by binding to and eliminating cancer-causing chemicals from the colon. Fresh fruit has small but significant amounts of vitamin-A, and flavonoid pigments such as carotene-ß
