碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 99 === In an effort to improve the nations competitiveness, the Executive Yuan plans to promote Digital Convergence policies, requesting domestic fixed network companies to invest in the construction of Fiber To The Home (FTTH), starting from the year 2010. The construction is estimated to last five years, and the goal aims to provide optical fiber coverage for over 80 percents of households nationwide, each with a bandwidth of over 100Mbps, by the year 2015. Therefore, starting from year 2011, domestic telecom and cable TV companies have eagerly started investing in construction of FTTH in order to prepare for the new age of Digital Convergence. For the Last Mile Access Network system to construct FTTH, there are three important factors to consider. First, it must permit high capacity; second, it should be low cost; third, it should be easy to construct. The need for high capacity can be met by utilizing the structure of Passive Optical Network (PON). However, the demand for lower cost is harder to fulfill due to the varying locations of Optical Splitter posing different costs for construction. In this Thesis, the discussion focuses on the difference in cost for constructing Optical Splitter in different locations such as the Telecommunications Equipment Room (TER), Main Distribution Box, Handhole Fiber Optic Junction Box, or the Fiber Distribution Hub (FDH). The findings show that by constructing the Optical Splitter in the TER, the cost can be reduced the most. In the current pipelines, there are still many twisted pair copper cables designed for Asymmetrical Digital Subscriber Line (ADSL) and Public Switched Telephone Network (PSTN). Because it is not possible to have the current twisted pair cables removed and the new fiber optic cables installed at the same time, we suggest that by using outdoor fabric innerduct, it will be possible to utilize the current pipelines more effectively, allowing the construction to become easier; as it avoids excavating roads for construction, the cost is further reduced. When setting up fiber optic cables in old buildings, the fact that old pipelines and cable boxes house cables from different companies will present a major problem. To solve this problem, it is suggested that a new method of using a combination of indoor fabric innerduct and micro-bundle fiber optic cables will facilitate the construction in older buildings, and as a result allows FTTH construction to be completed more quickly.
