...In the world of cabling there are two types of cables and they are Copper and Fiber Optics. Some companies chose fiber over copper but those companies have the money to use Fiber Optics and some just go with copper because it is cheaper to use. Each of these two cables has its own strengths and weaknesses. Copper: Conductivity and Heat Resistant Copper wires are second only to silver when it comes to electrical conductivity. Compared with other non-precious metals, copper wires can handle a wider load of electrical power, allowing it to use less insulation and armoring. They have high resistance to heat, eliminating most issues of overloading. Copper wires are also resistant to corrosion. Although patina, a tarnish produced by oxidation, might be present, the material will not lose functionality. Malleability and Ductility Copper has a high ductility, allowing wires thinner than human hair strands. Malleability allows it to be bent into nearly any form without the threat of breaking. Copper is used to create thick electrical cable wires within electrical posts and in applications where very thin wires are need, such as in headphone wires. Small Amounts of Electricity Although copper wires are excellent conductors, it does not perform very well when handling very exact amounts of small electrical charges. Copper wires are usually not used in high-tech automotive parts and semiconductors because of its inability to control electrical surges. Manufacturers and makers of...

...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...

...UNIT 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...

...The transition from a Socialist approach to a free market approach and the rise of a new high-tech sector are two remarkable shifts that have occurred in the last two decades in Israel. In the face of these changes, human resource (HR) practitioners are currently expected to assume new roles, adopt different work values, and apply appropriate strategies. HR managers in the low-tech industry still adhere to traditional values and strategies, including a reliance on trade unions and an emphasis on job security and the employees’ years of work experience and seniority as key criteria for promotion. In the emerging high-tech sector, HR managers have adopted new values and developed new strategies, including human resource management programs, employee empowerment, higher salaries and better benefits, while placing an emphasis on employees’ talents and qualifications.

...I think before going into details, we should understand what is backbone. After a lot of research, I came up this definition; a backbone is a means of connecting two or more LANs. It provides a transmission channel for packets being transmitted from one LAN to another. After connection to a backbone, a LAN may remain distinct or be merged with another. Backbone networks can be applied to a single building environment as well as to campus environments, where the backbone is used to connect LANs in different buildings. Parallel backbone: I think parallel back is the best worth it for any company. The additional cost of setting up a parallel backbone can be well worth the money. The design of this type of backbone consists of using two cables routed between the routers and switches. While there are additional initial costs of installing a parallel backbone, the benefits can quickly outweigh these costs. However if company wants to save some money, they can use distribute network. It consists of a number of connectivity devices connected to a series of central connectivity devices, such as hubs, switches, or routers, in a hierarchy. This kind of topology allows for simple expansion and limited capital outlay for growth, because more layers of devices can be added to existing layers The enterprise network is challenging because it rapidly changing as new applications and architectures, including Linux, computing clusters, voice over IP applications, become central to the business...

...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, shorts, damaged cables, and interference with other systems...

...The ethical issue at Bryson Corporation is whether or not Stanton Wong, the quality supervisor, should ignore defects in a batch of laminated cable they had produced. As directed by his plant manager Harry Jackson, Stanton still should supply their client’s inspector with the defected cables. According to protocol, Bryson Corporation required a test failure be reported for such results. The cables are used to assembly fuses in missiles for the U.S. military. If there were any faulty cables used in production, it could result in severe consequences. Many innocent civilians and soldiers can possibly be harmed. If I were Stanton Wong, I would not give the client the defected cables. I would definitely contact senior management and disclose them of the situation at the plant. As the quality supervisor, I’m responsible for the all the cables and if a cable isn’t up to par, I would be held liable. Additionally, I would approach Jane Conway, the client’s inspector, and request her to perform her own elevated seal heat test from now on. This scenario says a lot about the ethical situation at Bryson Corporation. It is quite obvious that Bryson Corporation does not have effective ethical precautions in place. They only seem to be concerned with making a profit for the company. As an independent ethical consultant, I would suggest to Bryson Corporation to provide an ethics-training course to all current and future management and employees. It would raise ethical awareness and provide...

...http://ammtiac.alionscience.com/quarterly Larry X Schneider Pulsed Power Sciences Center Sandia National Laboratories Albuquerque, NM The article entitled “Wired for Success: Ensuring Aircraft Wiring Integrity Requires a Proactive Systems Approach”, which was published in Vol. 8, No. 3 of the AMPTIAC Quarterly (a predecessor to the AMMTIAC Quarterly), established the importance of maintaining wiring integrity, especially in aging aircraft. The article also emphasized the need for nondestructive approaches for evaluating the integrity of wiring systems and components. The current article answers the mail in terms of providing a nondestructive inspection (NDI) method to proactively ensure wiring integrity. – Editor INTRODUCTION Detecting and locating insulation defects in wiring systems is a nontrivial challenge. Ideally, the diagnostic should be nondestructive, capable of detecting a variety of insulation defects, such as cracking, chaffing, and abrasion, and be able to locate the defect accurately to reduce potential inspection and maintenance costs. The diagnostic should also have a low rate of false detection. Complicating this quest is the nature of complex wiring systems. For example, aircraft wiring systems are comprised of harnesses containing periodically bound single wire pairs* which create highly non-uniform impedance characteristics due to the varying distance between wire pairs. Insulation defects may also be physically small, resulting in...
