在本篇論文中，我們提出一個新型監控系統SPMS（Simple PON Monitoring System），應用於分時多工被動光學網路（Time Division Multiplexing Passive Optical Network, TDM-PON）光纖斷點偵測，此系統具備架構簡單、低成本與自動即時偵測等優點，SPMS監控模組主要使用成本較低的Fabry-Perot 雷射二極體，利用外加控制電路產生順向與逆向偏壓，製成具有發射器及接受器切換功能的雙向窄頻FP-LD收發器，在搭配AT89S52單晶片微處理器產生與處理每一個用戶端設備光學網路單元（Optical Network Unit, ONU）監控信號，以監控光分歧器與ONU間之光纖連線狀態，監控過程能即時反應網路狀態，且不影響TDM-PON網路之運作。本論文亦透過實驗方式，使用1：16與1：32光分歧器以點對多點方式銜接SPMS監控模組；成功驗證其可行性與可擴充性，預估監控一個128 ONU的TDM-PON網路，整個SPMS監控系統的成本可低於300美元。

In this thesis, we propose a new monitoring system for fiber outage detecting in Time Division Multiplexing Passive Optical Network (TDM-PON) that is called SPMS (Simple PON Monitoring System). The advantages of this system have simple, cost-effective and detection active. SPMS monitoring modules that use cheap Fabry-Perot laser diode with an external control circuit which mainly is a combination of switchable forward biased and reverse biased circuit can act as a switchable bidirectional optical transceiver with a narrowband transmission capability. It combines the AT89S52 microprocessor for the generation and dealing with the monitoring signals at each ONU in customer side that can essentially identify the fiber fault without interrupting the services when monitoring branch fiber status between optical splitter and ONU. This thesis also uses 1:16 and 1:32 optical splitter to connect SPMS monitoring module through point-to-multipoint by the experiment which successfully verified the feasibility and scalability. We estimate that the material cost to build an optical network monitor system for a TDM-PON network with 128 ONUs is lower than 300 US$.
