摘要: | 在本論文中,主要重點在設計製作出可供32頻道數位直播衛星(DVB-S)信號分配於16個用戶使用之光纖收發機,另外此收發機亦可應用於多點式多頻道系統(MMDS)及當地多點分佈系統(LMDS)的信號分配之用。文中並對所製作出的收發機作性能測試,測試項目包括發射機及接收機的反射損耗(return loss) -S11及S22、全系統的S21值、系統操作時的CNR值及GTB值等,所量測的CNR值並有理論值加以對照。 In this thesis, we design and implement an optical fiber transceiver for distributing digital direct broadcast satellite (DBS) signals. The transceiver can also be applied to distribute multi-channel multi-point distribution systems (MMDS) and local multi-point distribution systems (LMDS) Also, we test the performance of my transceiver. The tested items include the return loss-S11 and S22 of the transmitter and receiver,S21 of the whole system, CNR, and C/CTB of the transceiver. The measured CNA values are also compared with theoretical CNR values. |
