...Unit 6 Assignment 1 Cable Testers Today we will be discussing different types of cable testers. There are many different types of cable testers. Some would include: wire-map testers, continuity testers, tone generators, time-domain reflectometers, fiber-optic power meters, fiber-optic test sources, optical loss test set, optical time-domain reflectometers, fiber-optic inspection microscopes, visual fault locators, and multifunction cable scanners. We will only be talking about three of these testers. Those three are wire-map testers, time domain-reflectometers, and optical loss test sets. Wire-map testers are testers that transmit signals through each wire in a copper twisted pair cable to determine if it is connected to the correct pin at each end. Wire-map testers detect misplaced wires, broken or unconnected wires, and shorts. The more expensive types of wire-map testers are capable of detecting all problems that can render a cable run inoperable. Though the best models of these can be costly, being able to determine the exact problem immediately is much better than having to keep guessing and checking. I believe that these should be with every technician who values there time in the field, and doesn’t want to spend hours defining a problem only to find more faults. Personally I think these testers should be in EVERY tool kit for wire techs. This could help save a significant amount of time determining the problem with cables. Time domain-reflectometers are the next piece...

...Wire-Map Testers A wire-map tester transmits signals through each wire in a copper twisted-pair cable to determine if it is connected to the correct pin at each end. Wire-map testers detect transposed wires, opens, and shorts which are all problems that can render a cable useless. A wire-map tester consists of a remote unit that you attach to the far end of a connection and the battery-operated, handheld main unit that displays the results. Typically, the tester displays various codes to describe the type of faults it finds, so you know which part of the cable you messed up on or what else may be wrong with it. Tone Generators Tone generators are the simplest type of copper cable tester. A tone generator is made up of two parts, a tone generator and a probe. These are sometimes referred to as a fox and hound wire tracer. With a standard jack, you connect to the cable the unit that transmits a signal, or, with an alligator clip, you connect the unit to an individual wire. The other unit is an inductive amplifier, which is a pen like probe that emits an audible tone when touched to the other end of the conductor. Tone generators are most often used to locate a specific connection in a punch-down block. Using a tone generator is extremely time-consuming and it is nearly as prone to errors as the cable installation. Time-Domain Reflectometers A TDR is the primary tool used to determine the length of a copper cable and to locate the impedance variations that are caused by opens...

...6. ASSIGMENT 1. CABLE TESTERS. THE THREE CABLES TESTERS I WOULD PICK IN MY LINE UP WOULD BE THE OPTICAL LOSS TEST SET AND TEST KIT, THE TDR, AND THE TONE GENERATORS. THE OPTICAL LOSS TEST SET AND KITS WORKS MORE SO IN A LAB BASED SET UP THEN OUT ON THE FIELD BUT THE TEST KITS IS MORE FAVORABLE BY FIBER TECHS BECAUSE IT HAS A POWER METER AND LIGHT SOURCE THAT ARE MADE TO WORK TOGETHER. THE TDR (TIME DOMAIN REFLECTOR) IS A TOOL THAT IS USED BE SENDING A TONE OR / BEAM OF LIGHT (WITH A DATA ON IT SOME TIMES) AND WILL MEASURE HOW LONG IT TOOK FOR THAT TONE TO REACH THE DESTINE PLACE AND OR BACK TO THE SENDER FROM WHICH IT CAME. AND DEPENDING ON HOW LONG IT TAKES TO COME BACK (IF IT EVER DOES) WILL USUALLY LET YOU KNOW WHERE YOUR FAULT IS IN TYOU NETWORK CABLING THE TONE GENERATOR IS USED BY GENERATING A CERATIN TONE ALONG THE CABLING TO LET YOU KNOW WHERE EXACTLY YOU INCOSISTANCIES ARE WITH IN THAT SPECIFIC CABLE. THE OPTICAL LOSS TEST SET AND TEST KITS WILL SEEM TO WORK BEST WITH FIBER BASED LAYOUT, THE TIME DEFLECTIVE DOMAIN WILL WORK BEST ON THICKNET CABLING SET UPS AND THE TONE GENERATOR WILL WORK BEST ON COPPER/COAXIL LIKE SET UPS. THE TWO TESTER I THINK SHOULD BE IN EVER TECHS INSTALL KITS WILL BE THE TDR AND THE OPTICAL LOSS TEST SET AND TEST KITS THE REASON WHY IS THAT BOTH OF THESE TESTERS CAN SEND TESTING SIGNALS DOWN A CABLE THAT GOES IN OR THRU WALL OR TIGHT SPACES THAT THE HUMAN HAND CANT REACH NOT THE EYE CAN SEE, ALSO MOST OF THESE TESTERS WILL GIVE YOU A...

From there we will map out all other room required to be configured into the network. The cabling of choice is Cat5e. It’s inexpensive, easy to maintain, test, run, and supports the required data transmission rates. Fiber would be great but it is much more costly and susceptible to 90 degree bends. Continuity tester will tell us if the cable to be bun is in good working condition before we actual setup the network. Easier to prevent problems before they have the opportunity to occur. Crimpers are essential to terminate runs at their desired locations with RJ-45 connectors, thru out the building. Whether they be at a work station, hub or server. Configuring connectors vs. wall jacks saves time and cost, and work just as well with the proper crimper. Patch cords will be used to connect ports to servers/ switches in the telecommunications room to ensure connect ability. Cable toners will help us identify cable runs from end to end. This will help us in preventing connectivity issues thru out the system, ensuring all ports are properly connected from end to end. Fish tape is essential for pulling cable runs through tight spaces such...

...Unit 6 Assignment 1: Cable Testers In almost every application in dealing with cable installations, cable testing is a must. Some methods of testing cables include testing for attenuation, continuity testers, DC Resistance, a wire mapper and cable length. In all cable types- copper or fiber, 10BASE-T or 100BASEFX, the standards are constantly being changed and developed into a new standard for all future technologies. When testing cable, you can guarantee that the users will be satisfied when all connections prove effective for not just uninterrupted transmission but correct bandwidths to support. A wire mapper is the most common tool. It simply provides a test of a standard Cat5 cable to ensure each individual wire not only carries a strong signal through the entire length of the route, but it proves if each wire ends up in the correct pin number on the opposite end to receive the transmission. It will give the technician an idea if a cable has a short, or if it is a crossover cable. It is also very useful with telephone connections. It should be a part of each cable installation kit. Another common tool is a continuity tester. It shows if there is a direct connection between two points. If there is a closed electrical pathway for the tester to detect, then the device will make a sound. This is useful not only to test for a short, but also to determine and identify which cable is which in a closet full of many cables. This is also a very important tool in any application...

...Jonathan Hunt 7/23/14 Unit 6 Assignment 1 Cable Testers After installing cables in a building it is necessary to test them to make sure they are functional and did not get damaged during the install. There are many tools that can be used for testing cables, the type of cable that you are working with will determine the kind of tester that you will need. When working with copper cables one of the tools you can use is a tone generator, this tool can be used to test cables for crossovers, and shorts. This tool is most commonly used for testing punch down blocks in telecommunication lines. Another tool that is handy for copper wires is a wire map tester. You can use this tool to send a signal down the cable and make sure that the pin connections on both sides are correct. This tool can also detect a short in a wire as well as openings in the line. This is a fairly inexpensive tool and would be a good one to include in your kit if you are installing cables. Continuity testers can also be used in place of a wire map tester and are also inexpensive. It would be recommended to have at least one of these tools in your toolkit. Personally I would choose the wire map tester. If you are working with fiber optic cables you need to have a completely different set of tools because you are now dealing with light transmission as opposed to electrical current. Fiber optic power meters are used to detect the strength of light going down the cable. Depending on the type of fiber that you are...

...Cable Testers: How They Work and With Which Cable System ITT Technical Institute Physical Networking – NT1310 10/27/2014 After any size cable installation the technicians should check for errors, performance issues, signal loss and check for equipment that may cause interference and degrade network performance. The following paragraphs describe three (3) cable testers and how they work and which cable system(s) they are most suitable for. The first tester is the wire-mapper. Wire-mappers are used primarily with copper twisted-pair cable installations. These devices, according to Oliviero and Woodward (2011, p.422, 441) “Transmit signals through each pair in a twisted-pair cable to determine if it is connected correctly to the correct pin at each end.” The second tool is the tone generator. A tone generator is a two-piece unit that consists of a tone generator and a probe. This type of tester's primary function, amongst installers, is to identify specific locations in a punch-down block then label accordingly. According to Oliviero and Woodward (2011, p.442-443), these testers “Transmit[s] a signal, or, with an alligator clip, you connect the unit to an individual wire. The other unit is an inductive amplifier, which is a pen-like probe that emits an audible tone when touched to the other end of the conductor.” Primary functions are identify a particular cable within a bundle and to test for opens, shorts, and miswires of individual wires. Unfortunately, there is...

...Connector Installations * Strip the cable of its protective outside jacket about 3-6 inches from the end. This can be done with the cabling scissors by applying pressure from the scissors to the cable and rotating the scissors around the cable. After you have punctured the cables jacket, you should be able pull the jacket off easily leaving exposed wires. * Expose the wire a little further. Stripping the cable can cut and damage the wires at the area that we cut the cable so we want to expose about 6 more inches of fresh wires. Most twisted pair cables have a small string inside the cable to assist with this. * If your cable has the small string. Cut the string after you have enough exposed cable. * Untwist the wires completely to the jacket. Place the wires into the appropriate color slot on the jack. Make sure to place the wires as tightly as possible in the slots in regards to the jacket. There should be as little exposed and untwisted wire as possible to keep the signal strength as high as possible. Make sure to place the White/Blue in the White/Blue spot and not the solid Blue spot. The White/Color wire is not the same as the solid color. * Terminate each wire. After all the wires are in the correct spot and double checked to make sure as little amount of exposed wires will be left as possible, use the punch down tool with the 110 blade and terminate each wire individually. The 110 blade will fully cover the wire connector on the jack. Push down until...

...Video Game Design Career Essay I was a kid, maybe six or seven years old when I first played one of those small portable video games, the famous Nintendo gameboy advance. Since that day I became a lover of video games, dreaming of becoming a creator or game designer, as it is called today. As I play more games, more grew in me the dream not only to play the game, but Also to create them; in fact I have come up with many nice thoughts about video games from what I have played and I believed one day my dream will come true when I will create my own game, hoping such game will become a famous game. After doing researches, I found that in fact, the video game industry it is a huge business managing billions of dollars, and that in order to create video game from just the game’s idea until the end step, a lot of different People with different educational background and training is needed. So, the questions now are, what part of this long chain of different positions I am interested for? What position within this multi-billions of industry will give me a major satisfaction? What position will give me the better income? Are universities or colleges in Puerto Rico offering courses for all these positions? Well, I think that I will only find answers researching more about the video games industry and those college in Puerto Rico teaching related course of study. I hope the next paragraphs will provide more information that helps to find answers about doubts in this field of video...

...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...
