Fiber optics technology - Essay Example ITU-T G.651 and ITU-T G.652 (standard SMF) are the two compositional standards (Alwayn, 2004). Standards that relate to performance govern transmitters and receivers and include; Optical Transport Network the, Synchronous Digital Hierarchy, etc. Other standards are developed for specific niches. For instance, fiber optics in satellite communication begs other standards to adhere to. The deposition of dopants can be done in three standard ways: inside, outside and axial vapor deposition (Held, 1999). Moreover, advances in the use fiber optic systems has created a demand for standards that enable interoperability between telephone companies and interexchange carriers. Synchronous Digital Hierarchy (SDH) in Europe and Synchronous Optical Network (SONET) in North America (Held, 1999) are data transportation vehicle capable of supporting data rates in gigabyte range. There is not just one way of implementing fiber optic technology. For instance, the most common way for this implementation is a high-speed fiber optic local area network (LAN). Before implementing this technology, a feasibility study is made. If a company needs to go into an area where there are no pre-existing cable networks then implementation is much easier. Fiber optic technology is very different from DSL services, therefore, implementing a new technology in a blank area is much easier. However, if there are copper wires installed for transmitting data then cost justifications, minimizing disruptions for the use of SML and the cost for connecting to NPS backbone LAN, need to be made (Ee, 2004). The demand for high-speed internet usually drives the service providers to move to a better technology. The greatest hurdle preventing the widespread implementation of fiber optics is its cost. Implementing new fiber optic network is a troublesome task especially when old infrastructures like DSL and cable are already serving the customers

Statement of purpose in Architecture Essay Example | Topics and Well Written Essays - 250 words

Statement of purpose in Architecture - Essay Example It gave me an opportunity to think about what the meaning and values of architecture are and how architecture can affect not just a person, but an entire society. With five years of architectural study, research and practice, it helped me to establish a consciousness that kept me explaining, and questioning my surroundings. Though I was often confused, my studies inspired me to work through the many different changes in my living environment. It is a frustrated process because of the unknown and the fear of change. It is true that I was always been fettered and manipulated by some problems that were brought about by the change. People try to find a solution because there is a problem. However, the solution as part of the change can also bring many new problems and finally take us into a death loop. For example, what I learned from the structure class in the third year is what kind of relationship exists between the physical force and an architectural reaction been examined. Even though the physical force and the reaction influence each other, they integrate themselves into a co-work system so that they rely on each other and amplify their advantage. Also, when I drove around in Los Angeles with my mother, she kept asking me, â€Å"where is Los Angeles?† Is it because the highly developed infrastructure system alienate the emotion between people and cities? Although the process was frustrating and lowered my confidence, the results can always be inspirational. The undergraduate program flamed my passion in discovering architectural interpretations. Pursuing of a master’s degree in architecture will give me an excellent chance to explore further intricacies of architecture. With a Chinese international background, I always have a more diverse view to think and analyze the results that have been obtained. Through five years of architectural studies, I was very excited and happy to graduate
