本論文提出一個可動態調整頻寬的遠端泵激分時分波多工被動光網路的架構。我們利用混合型分時多工被動光網路/分波多工被動光網路技術解決鏈路傳輸數位訊號時所發生的頻寬超載或輕負載問題，而本論文亦提出射頻上載光纖技術與混合型分時多工被動光網路整合，用以達成射頻類比訊號的動態調整頻寬功能，且由於本架構是以原有的分時多工被動光網路及分波多工被動光網路作為基礎，故系統升級容易，免除重新建置架構的成本及時間費用。
在我們架構中，為了達到波長路由的效果，我們捨棄了複雜的光開關裝置，轉而利用波長光柵路由器元件的旋轉特性，做到光網路節點及光線路終點頻寬分配功能及調整基台開關數目，以達到降低成本及節省能源的目的。此外，為了補償在遠端節點端使用分路器及波長光柵路由器等元件的功率損失，還在遠端增添一摻鉺光纖，並利用遠端泵激的方式，提供上下行訊號增。
同時我們建置一個實驗平台，驗證下行10-Gb/s、上行1.25-Gb/s的數位傳輸系統及全球行動通訊系統類比傳輸系統在可動態調整頻寬的遠端泵激分時分波多工被動光網路架構上的可行性。

This research demonstrates the architecture of Remotely Pumped hybrid PON systems that allow adjusting user bandwidth dynamically. The hybrid PON system combines the time-division-multiplexing (TDM) and the wavelength-division-multiplexing (WDM) passive optical networks (PONs) into one compact architecture.The problem of bandwidth overload and light load while transmitting digital signal can be solved by using the technology of hybrid TDM/WDM PON. We can integrate the RoF technology and hybrid TDM/WDM PON to achieve the function of adjusting bandwidth dynamically for transmitting RF analog signals. Because the architecture is based on the original TDM and WDM PON, this system is easy to upgrade, low cost and has low istallation time.
In order to achieve wavelength routing in our framework, we use the cyclic characteristic of an array wavelength grating (AWG) instead of a complex optical switching device. It can not only allocate flexible bandwidth in both opticwouls network unit (ONU) and optical line termination (OLT), but also adjust the number of base stations.
Furthermore, we add an erbium-doped fiber (EDF) in the remote node to compensate the power loss due to the fiber transmission loss and insertion loss from the splitter and AWG in the remote node, the EDF is pumped by a high-power laser at the OLT. The uplink and downlink signal gain can be achieved by using the remote pumping scheme.awg
We set up an experimental platform to verify the transmission performance for 10-Gb/s downstream and 1.25-Gb/s uplink sigmals. The feasibility of the Remotely Pumped TDM/WDM PON is demonstrated by adjusting the bandwidth for GSM transmission.
