中文摘要 | 在用戶迴路上以光纖取代銅線除了財閥寬低損耗外,亦具有重量輕壽命不受電磁干擾的優點, 但是昂貴的光電元件一直是限制用戶迴路光纖化的主要因索,一種稱作被動式光纖網路的系統 (Passive Optical Network:PON),可由多個用戶共用一個光網路單元 (Optical Network Unit:ONU),多個光網路單元則共用一光纖配送網路及一個主數位終端 (Host Digital Terminal:HDT),籍由成本的分攤及被動式星型配送網路的設計,PON 系統非常適合在用戶迴路上提供家庭用戶及小型商業用戶語音、數據及影像的服務,在本文中我們將描述本所正在發展的 51.84Mbps PON系統的架構,硬體及軟體的結構及其主要特性。 |
英文摘要 | Besides high bandwidth and low loss, fiber has light weight and EMI-free advantages, which is the main reason of replacing twisted pairs in deploying subscriber loops in recent years. But the major constraint of fiberzing subscriber loop is still the expensive cost of op to-electronics components. A point-to-multipoint Passive Optical Network (PON) has economic advanateges in delivering telecommunications services due to resources sharing over a number of customers. By way of the passive star distribution and cost sharing by all subscribers, PON is very adequate to provid voice/data, and image/video services in residential and small-busineess area. This paper introduces the architecture, hardware/software structure, and features of a 51.84 Mbps Passive Optical Subscriber Loop System. |
