中文摘要 | 在用戶對電信服務品質與網路頻寬的迫切需求下,加速了FTTC/B光繼接取迴路系統的規劃與建設。其中戶外型光終端設備因置放於戶外,將面臨本土高溫多雨環境及電力如何供應等問題。本文針對本土環境因素,探討並提供戶外機箱溫溼度規格建議。在供電問題上,由於服務型態的增加,用戶端由原來的POTS、ISDN加上ADSL等高速數據服務,使得供電需求增加,熱損耗也相對提升,如何利用既有資源及建立一套本土化供電架構,為本文另一探討主題,本文就本地供電與集中供電的供電架構、可靠度與維運,及經濟效益提出本土化供電架構評估建議。 |
英文摘要 | The subscriber’s urgent needs of telecom service quality and network bandwidth speed up the planning and development of Fiber-to-the-Curb/Building (FTTC/B) system. Since outdoor Optical Network Units (ONU) of FTTC are installed in the outside plant, there are many technical problems to be solved. One is how to sustain the high temperature and rainy environment, and another is how to provide the electrical power to ONUs. Due to the increasing demands of service types, the subscriber lines provide not only traditional narrowband services but also the ADSL broadband service. The increase of average power per living unit is thus driving up the base powering load demand from power plant, which in turn increases heat dissipation demands in the outdoor enclosures. This article describes the work that was done by CHTTL for technical evaluation and provides the specification recommendation of temperature and humidity for the outdoor ONU under native environment. It also provides native powering structure recommendation for powering structure, reliability, maintenance, and economic benefit for large-scale implementations. |
