臺灣博碩士論文加值系統

在這篇論文裡, 我們設計並製造了供HFC網路使用的EDFA. 我們首先分析EDFA的特性,特別是增益模型及增益動態.
最後,我們設計並製造了兩種放大器; 一種供有線電視頭端功率放大器使用; 另一種則在DWDM的環境下使用.

In this thesis, we have designed and implemented EDFAs for HFC networks applications. We first studied the properties of EDFA, especially the gain model and gain dynamics. Finally, we designed and implemented two kind of EDFAs, one for power amplifiers in the head end and another one is suitably used with DWDM techniques.
