本論文提出一基於複合被動光網路(Hybrid PON)且具動態頻寬分配與節能的行動網路架構，並結合射頻上載光纖技術(Radio over fiber, RoF)，成功解決了無線基地台在傳輸無線訊號時所發生的頻寬負載問題。首先，針對雜訊指數(Noise Figure, NF)、光電轉換匹配問題進行優化，並提出一適用於傳輸LTE-TDD訊號之被動光網路架構，藉由在遠端(Remote Node, RN)使用低密度波長路由器與分歧器來提供兩種不同模式的服務(Broadcasting Mode and Unicasting Mode)，且依據行動通訊流量變化，在局端(Central Office, CO)即可決定無線基地台使用數量，達到遠端動態調整頻寬與節能之目的。
實驗結果顯示，本論文所提出的被動光網路架構在不同頻寬下之LTE-TDD訊號，兩種不同模式的服務均可達到3GPP所規定的訊號誤差向量(低於8%)要求，且透過無線基地台之功率損耗計算，基於本論文所提出之架構可達到最大約50%節能之目的。

This research proposes a system of hybrid passive optical network (PON) and radio over fiber (RoF) scheme to provide service and operation dynamic bandwidth allocation (DBA) and energy-efficient to handle variation of traffic load of a long-term evolution (LTE) mobile network. The noise figure (NF) and matching circuit of optical-electric conversion module are investigated to meet the performance specification of error vector magnitude (EVM) for LTE-TDD signal. In order to achieve remote dynamically bandwidth allocation and energy saving purposes, a hybrid PON architecture with an coarse wavelength division multiplexing (CWDM) and splitter at the remote node are used to provide both broadcast and unicast services. Energy saving can be achieved by using the RoF scheme and the adjustment of the number of working base stations based on the traffic load.
The experimental show that both the broadcast and unicast channels can provide good LTE signal transmission that satisfies the EVM requirement of the 3GPP LTE system (< 8%). Moreover, the power consumption calculated based on a typical traffic load example. The calculation demonstrates a maximal 50% energy saving by using the proposed architecture.
