Souvenir 2013 Optical Fiber Project & its Impact Background In the initial days‚ the backhaul of telecom equipments relied on microwave and satellite communication. The rapid proliferation of various telecom technologies and the desire to penetrate larger market segments resulted in high national and international traffic. The high cost of space segments for statellite communications and limited capacity of Microwave links compelled Nepal Telecom to embrace the optical fiber deployment to cater high

description on the functions of the main cell components of the body cell. The cell membrane : is something that lets some things in and some things out of the cell. It is an outer cover for the cell. If the cell membrane was non existences the cell would spill all over the place. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell‚ while keeping other substances out. It is composed of a thin‚ double-layered sheet of lipids‚ around the Cell

anderson Fri‚ Jan 7‚ 2011 Mr. Tyson Body Image and Pop Culture Body Image‚ in the Merriam- Dictionary it states that it is “a subjective picture of one’s own physical appearance established both by self-observation and by noting the reactions of others”. Millions of people all around the world have an obsession‚ rather a secret obsession. That obsession is about how they look‚ or in other words their body image. Many People wouldn’t mind having a flatter stomach and

Week three understanding fats and fibers There are four major fat types they are known as; monounsaturated fats‚ polyunsaturated fats‚ saturated fats‚ Tran’s fats. Saturated fat and Tran’s fat are two fats classified as bad fats. We should limit these types in our daily diets. Saturated fats are for the most part of found in red meat‚ and dairy products. Trans fats are super unhealthy‚ we should avoid eating them period. Tran’s fats are primarily found in pre mixed products such as; snack

Fiber Optic Safety Rules 1) Keep all food and beverages out of the work area. If fiber particles are ingested they can cause internal hemorrhaging 2) Do not smoke while working with fiber optic systems. 3) Always wear safety glasses with side shields. Treat fiber optic splinters the same as you would glass splinters. 4) Never look directly into the end of fiber cables until you are positive that there is no light source at the other end. Use a fiber optic power meter to make certain the

Fiber Optic Connector Assembly The three fiber geometry parameters that have the greatest impact on splicing performance include the following: Cladding diameter—the outside diameter of the cladding glass region. core/clad concentricity (or core-to-cladding offset)—how well the core is centered in the cladding glass region fiber curl—the amount of curvature over a fixed length of fiber These parameters are determined and controlled during the fiber-manufacturing process. As fiber is cut and

Function of Liver * The liver is a part of the digestive system‚ but it does much more than simply process food intake. It is responsible for producing substances that will break down fats and lipids‚ making foods more digestible. vIt also produces several amino acids‚ which are essential to protein production‚ without which a body could not function. The liver produces much of the cholesterol in a body‚ whether healthy or unhealthy. Aside from the liver’s production abilities‚ it also acts as

spreading of a light pulse as it travels down a fiber when light pulses launched close together(high data rates) spread too much and result in errors and a loss of information. The spectral width determines the number of different wavelengths that are emitted from LED or laser. One way to reduce chromatic dispersion is to narrow the spectral width of the transmitter. Chromatic dispersion can be compensated for with the use of dispersion-shifted fiber (DSF). Laser has a more narrow spectral width
