本論文提出一整合自發放射光源與半導體光放大器且利用遠端泵激之分波多工被動光網路系統，實現上下行10 Gb/s對稱傳輸。吾人將寬頻譜光源放置於局端利用分波多工器將自發放射光源做頻譜分配，經由半導體光放大器抑制寬頻譜光源過強度雜訊，可有效改善寬頻譜光源訊號雜訊比限制，且利用大有效面積光纖降低色散效應對系統的影響，以達到25公里傳輸距離。此外用戶端透過交互作種架構與利用反射式調變器提供上行光源與訊號調變，可充分利用降雜訊的寬頻譜光源作為上行傳輸使用。
為補償上下行被動元件及調變造成之功率損耗，利用遠端泵激架構，在遠端補償光路損失，以提升上下行光訊號強度，並實現上下行各32通道之被動光網路架構。實驗結果顯示，利用自發放射光源作經分波多工器做頻譜分配，利用遠端泵激架構可達共計320 Gb/s之雙向傳輸。

We propose and demonstrate a remotely pumped WDM-PON architecture to achieve 10 Gb/s symmetrical transmission. In this scheme, a wideband amplified spontaneous emission (ASE) from an optical amplifier is sliced into multiple channels by an arrayed waveguide grating (AWG) and used as multi-channel optical sources for WDM-PON system. Each channel is noise suppressed by using a gain-saturated cascaded semiconductor optical amplifer (SOA) and then modulated at 10.7 Gb/s, assuming forward error correction (FEC) with 7% overheads. We also propose a cross-seeding scheme to provide uplink seeding light and use a reflected electro-absorption modulator (REAM) to encode the upstream signals. In order to achieve a transmission up to 25 km distance, we use a larger effective area fiber (LEAF) to reduce the dispersion effect. To compensate the loss by passive components and modulation, we employ a remotely pumped erbium-doped fiber amplifier (RP-EDFA) to provide extra gain for both downstream and upstream signals. The experimental results show that the downstream and upstream transmission can provide 10 Gb/s data rate over 25 km for 32 channels, which corresponds to a total capacity of 320 Gb/s, on each direction.
