Case Instructions – Zeal Optical Michael and Wink Jackson are receiving advice from 3 different individuals/experts: Scott Jaeger‚ Laura Kornish‚ and Dave Maney. For this assignment: 1. Identify the problems that Zeal has. It is helpful if you list these problems in the first paragraph of your case write-up. 2. Think about it: If you were the Jacksons‚ what would you do to grow your business‚ i.e. what are your recommendations? Why? Be specific. You can use advice from one or more of the

characteristics of the nerve fibres that make up the optic nerve. One of these is SD-OCT(Fig2)‚ a non contact‚ non-invasive method that enables physicians to obtain in vivo‚ high resolution (upto 5 microns) cross-sectional images of the retina. It is based on principle of low-coherence interferometry(Fig 3). By imaging a 3D cube of data it allows a detailed evaluation of the peripapillary area. Fig 2 : Cirrus HD OCT machine In low-coherence interferometry‚ light is sent along two optical paths‚ one being

The horizons of optical networks are much more than high speed physical layer transport. An intelligent optical network design must include higher network layer considerations. This is the only book currently on the market that addresses optical networks from the physical layer to the network layer and should be valuable for those who try to understand the intricacies of what optical networks can be. —Vincent Chan‚ Professor‚ MIT Department of Electrical Engineering and Computer Science This book

Disruptive and transformational technologies typically appeal to segments of the market that are undeserved‚ and not to the main stream of the market (Shane‚ 2009). These technologies have the ability to make traditional tools and processes obsolete virtually overnight. In this paper I use Netflix as an example of a disruptive technology and Toshiba– NEC’s HD-DVD as transformational technology. I begin with a discussion of disruptive technology. Afterwards‚ I will speak on the success of Netflix;

light bulbs and LEDs. 3. Laser-(light amplification by stimulated emission of radiation) used to provide the high-powered‚ tightly controlled light wavelengths necessary for high-speed‚ long-distance optical fiber transmission. 4. Output Pattern-is the energy couples into the core of the optical fiber. 5. Output Power- allows transmission distances. 6. Modulation Speed- is something that can limit the performance of a fiber-optic communication system. 7. Core Diameter Mismatch- will cause confusion

chemicals that make up the fiber must be deposited with precise control and symmetry to maintain consistent core/clad concentricity performance throughout the entire length of fiber. Fiber curl is the inherent curvature along a specific length of optical fiber that is exhibited

A splice is a permanent connection of two optical fibers. Once the two optical fibers are joined with a splice‚ they cannot be taken apart and put back together as they can if you join them using connectors. A splice is typically employed for one of three reasons: to repair a damaged cable‚ to extend the length of a cable‚ or to join two different cable types. (Andrew Olivier‚ 2011‚ p. 617) There are some things that can affect splicing performance. There is Cladding Diameter which occurs when the

mode optical fibers. This affects due to the length of the light that is emitted through wave lengths. The best way for one to avoid these affects is to make sure that the ratings match and the splicing is perfect along with the end faces meeting together. Next thing to discuss are the 3 factors for intrinsic performance. These factors are Numerical Aperture Mismatch‚ Core Diameter Mismatch‚ and Mode field Diameter Mismatch. A Numerical Aperture Mismatch can occur when the NA of one optical fiber

of Fiber Optics An optical fiber is a thin and flexible fiber that carries the light between the two ends of the fiber. Optical fibers are widely used in Fiber Optic Communications‚ which is the transmission over longer distances at higher bandwidths than other communications. A fiber optic communication system consists of three components: an optical transmitter‚ a fiber optic cable‚ and an optical receiver. The optical transmitter converts electrical signal to optical signal; the fiber cable
