Essay Fiber Optics

The medium comes in the form of a salvific complex of fiber optic cable and ROM,

When first thinking of fixed line networks they think of the coaxial cable (coax) which connects to their television and twisted pair terminated with a RG-11 plug for their phones and faxes. There two variation of coax that are used in networking, thicknet (RG8) and thinnet

14. Hybrid/Composite Cable : composite cable A communications cable having both optical and metallic signal-carrying components. Note 1: A cable having optical fiber(s) and a metallic component, e.g., a metallic

My decision to pursue a degree in optometry started from an unlikely source within the field of healthcare. I originally aspired to become a pharmacist and had extensive experience as a pharmacy technician throughout high school and the start of college. As I progressed I became more unsure of the profession, and did not feel as though as if I was making a difference. Patient interaction was minimal and I felt that having a more personable connection would make for a better healthcare professional. I always knew I wanted to become a healthcare professional, I just was not sure pharmacy was the path for me.

Coaxial cable consists of a core of copper wire surrounded by insulation, a braided metal shielding, and an outer cover.

It never fails to amaze me what end users will admit to when you ask the right questions. If you ask a user in a nonthreatening manner about any physical stress that the cable might have endured, they’ll usually tell you. Remember that most users have no idea that a fiber cable can be destroyed if stepped on or bent too sharply, or if they roll a chair over it.

Fiber Lasers were invented in 1963 and since the 1990's they have been advanced almost entirely by IPG Photonics Company. The fiber lasers are compact and can be rolled in coils and take in sunlight which increases its brightness and power by over 30%. This fiber laser is twice as strong as the solid state lasers (Extance). The High Energy Laser Mobile Demonstrator is a prototype mechanism that is placed in top of camouflaged trucks and shoots an invisible infrared laser at the enemy planes or weapons. Inside the truck an engineer sits in front of a computer and aims and shoots the invisible laser at the enemy. This laser is one of the best forms of defense because it only takes two cups of fuel and an outside energy source such as a generator, whereas a conventional inexpensive missile costs around 100,00 dollars per shot (Extance). The fiber laser only costs less than 10 dollars per shot. This makes the fiber lasers a very effective line of defense against flying targets. Other prototypes such as the LaWS laser systems have been designed to be placed on United States boats and are able to target smaller enemy boats. Direct Energy weapons use lasers and microwaves as a weapon. Although not many of these weapons

All over the world em waves are being used. One place where they use this is in the military. Where they use them on their missions to get what they need. It is really helpful to the rangers to have these gadgets that have waves. If they did not have these devices it would be way

Optical Fiber Corporation (OFC) is a financially successful, albeit relatively small manufacturer of multimode optical fibers. The company was founded in 1990. The founders were able to enter the market largely on the basis of acquiring patent licenses from larger optical fiber firms. These licenses restricted competition between the entities and provided OFC with instant access to optical fiber technology. In return, OFC’s customer base is limited by the license agreements and royalties of 7% on sales of licensed products (recently renegotiated to 9%) are paid to the licensors. Despite these handicaps the firm has grown in size and profitability. OFC makes several types

glass fibers which are commonly used in commercial industries. They are E-glass and S-glass; the E-glass has the lowest of all commercially available reinforcing fibers which makes the reason for its widespread use in the industry. The S-glass was originally developed for the aircraft components and missile casting; as they have the highest tensile strength of all fibers in use [29].

Analysts forecast the Global Fiber Laser market to grow at a CAGR of 21.9 percent over the period 2013-2018. One of the key factors contributing to this market growth is the increasing adoption of fiber lasers due to their superior attributes. The Global Fiber Laser market has also been witnessing increased R&D spending by vendors in the market. However, the uncertainty in lifespan of fiber lasers could pose a challenge to the growth of this market.

The OTDR is a device that measures distances to a reflection surface by measuring the time it takes for a lightwave pulse to reflect from the surface. Reflection surfaces include the ends of fiber cables, breaks in the fiber, splice locations, and connector locations. The ability to provide these measurements simplifies the fault location procedure for fiber systems.

One of the most interesting developments in recent years in the field of telecommunication is the use of laser light to carry information over large distances. It has been proved in

Light enters one end of the fiber from a light bulb, laser, or some other source, and travels essentially unimpeded all the way to the length of the fiber where it is intercepted by a photosensitive detector such as an electronic device or even the human eye. The distance of travel varies according to the use to anywhere from just a few inches to over one-hundred and fifty miles. Fiber optic cable can transmit large amounts of information over one-hundred and fifty miles almost instantaneously. “While it takes five hours to transmit the contents of an encyclopedia over copper wires, the entire work can be transmitted in less than a minute over fiber optics” (Yawn PG).
