NT1310 Unit 10 Lab 1 Building A New Structure- Problem Analysis

Eliminating Spark hazards: Fiber optic cables do not produce sparks since they do not carry current. Most electric potentials create small sparks which can be extremely dangerous in areas like chemical plants or oil refinery where air is contaminated with potentially explosive

Use some electrical tape to wrap the part of the cable that is damaged. You’ll want to wrap it about an inch above and below the damaged area to make sure that the wire is no longer exposed. The reason this works is because electrical tape is typically made from vinyl, and is designed to insulate the electrical wires it is exposed to. The tape will not melt or catch on fire

Fiber: A fiber cable is either multiple strands of fiber optic surrounded by insulation, or a single fiber strand surrounded by insulation.

Traditional cable frameworks utilize a lot of copper. In a few places, this copper is an target for robbery because of its worth on the scrap

Design technicians and engineers love to use carbon fibre in manufacturing as it has many desirable properties. First of all is its strength. Carbon fibre is five times stronger than steel and is twice as stiff [2]. The strands of carbon are lined up parallel to each other when producing a sheet. For maximum results in strength, the fibres must be parallel with the forces that will act upon that element, this is to make sure it can withstand the forces going through the object when in use.

A fiber optic cable is a network cable that contains strands of glass fibers within an insulated casing. There are designed for very high-performance data networking, long distance and telecommunications. Compare with wired cables, fiber optic cables give higher bandwidth and can transmit data over longer distances. Fiber optic cables support world's internet, telephone systems and cable television.

Companies that have been using fiber optics for a while may have forgotten about the disadvantages of using copper cable. They may have become accustomed to lower latency and stronger, more consistent signals.

However, composites are not wonder materials, in the aviation world, and do have their own disadvantages. Internal damage to composite materials, from a low speed impact, though it shows no external or surface evidence, could result in delamination between the internal layers, or plies of composite material. It is in these circumstances that structural engineers have concerns regarding complex repairs structural tolerances. Because of the threat of delamination, engineers who design composite structures take special care to make certain that loads placed on the composites are primarily in plane -- where the fibers are strong -- and that buckling does not occur. Compounding the difficulties confronting engineers, composites cannot be inspected for weakness or internal damage in the same way that metals can. Delamination and cracks in the composite matrix are usually internal to the composite and will not be visible from the surface. Techniques are available to find such faults -- such as the embedded sensors previously mentioned -- but they require a different methodology than that to which the

The purpose of this lab is was to expose students to the manufacturing, fabrication, and testing of composites. In addition, it provides students with experience analyzing tensile and bending failures of composites. Three tensile specimens and two bend test specimens were tested during this lab. The tensile specimens were a wet lay-up of bi-directional E-glass, and the bend specimens were made up of a nomex honeycomb core with pre-preg uni-carbon faces. The three tensile specimens were tested, their elastic modulus and ultimate tensile strength calculated, and these value were compared to published approximately equivalent material properties. The two bend test specimens were tested, their face bending stresses were calculated, the shear stress in the core was calculated, and the bending and shear stresses were compared to published approximately equivalent material properties. A failure mode analysis was conducted for both the tensile and bend test specimens. This report summarizes the theory, procedure, and machines associated with the lab. Furthermore, it graphically and verbally displays the results draw from lab, and provides conclusions to improve the lab in the future.

Next a cable IQ advanced IT kit with SC connectors is required. The Cable IQ Advanced IT Kit is designed to maximize the efficiency of any cable qualification job. Use the included Intelli-Tone 200 Probe to find cables quickly and definitively, even on active networks. The total cost of this is $2,274.00. Price can range depending on the brand. However, the recommended one in this case is Fluke Network cable IQ kit. Which costs $2,274.00.

Having the diameter of a human hair, Fibre Optics are thin and long strands of glass that have revolutionized the field of telecommunications and have had a huge part to play in the arrival of the Digital Age. Fibre Optics are transparent, flexible strands of fibre made from quality glass like silica or plastic mainly to transmit light from one end of its fibre to another. The structure of the fibre optic consists of three main parts:

In 1870, a person called John Tyndall demonstrated and experiment in which the water from one container flows to the another container where the water is on top container flows into the container which is at the bottom, then john projected a light beam on to the top container, he observed that the light followed a “zigzag” path in the curved water flow. Form that experiment he realized that light can also be transmitted. This is the first discovery of light transmitting in a path.

The fiber phase is usually made from materials that are usually stronger and have a higher modulus of elasticity than that of the matrix, but they are often very brittle [2]. Therefore, the matrix phase is usually the source of the composites’ ductility, whereas the fiber is the source of its strength.

Fiber optic cabling has the following components (starting in the center and working out): core, cladding, coating, strength member, and jacket. The design and function of each of these will be defined. The core is in the very center of the cable and is the medium of propagation for the signal. The core is made of silica glass or plastic (in the case of POF) with a high refractive index. The actual core is very small (compared to the wire gauges we are used to). Typical core sizes range from 8 microns (millionth of a meter) for single mode silica glass cores up to 1000 microns for multi mode POF. The cladding is a material of lower index of refraction which surrounds the core. This difference in index forms a mirror at the boundary of the core and cladding. Because of the lower index, it reflects the light back into the center of the core, forming an optical wave guide. This is the same effect as looking out
