中文摘要 | 現行電話網路要達成雙向寬頻傳輸有其困難,而把部份現有之電話網路光纖化將 是未來的趨勢。故在本文中提出一價格便宜之光纖網路,其架構易於取代現行電話網路之 硬體架構,而能輕易的達成寬頻且雙向之傳訊功能。然而,當網路光纖化後網路中多種光 源間會互相干擾,此種雜訊是多光源系統中不可忽略之因子,故如何降低多光源互擾雜訊 將是急待解決的問題。而如何在最大光干擾條件下增加光源數目也是吾人研究之重點。而 經過吾人估算整個系統大約可容許長距離終端客戶數目為二十多個,短距離終端客戶數目 卻無限制。 |
英文摘要 | It is difficult to transport broadband signals bidirectionally in the traditional telephone line except that optical fiber must be used in the network. However, cost is the main factor in adopting the optical network to give broadband services. Thus, we provide an cost-effective optical network to replace the traditional telephone line. Despite that optical network can provide high quality services, the multiple optical carriers interference noise must be taken into account, and such noise will seriously degrade the signal quality and limit the number of users. Thus, we want to study the impact of this noise to system performance, and also find some methods to reduce it. |
