在本篇論文中,我們提出並驗證目前有線電視HFC光纖同軸混合網路之特性利用EoC的技術,來達到解決最後一哩系統設計、測試及分析。
首先,以FTTB技術建構一個使用外部光源注入技術及光纖光柵為基礎之被動式光纖網路EPON系統,將連結有線電視頭端OLT設備之網際網路訊號,傳送至HFC網路中的最小單位FN內的ONU設備,並連接至HFC網路末端放大器後方新增之EoC設備中,透過EoC設備本身工作頻段之高抗雜訊能力,解決用戶端因垂直或水平線路之低頻返向訊號雜訊過大、高頻下行訊號衰減過多等問題,造成無法供裝CM而流失之網路服務客戶層。
  經實驗結果驗證,提出EoC之技術,在不需變更原有HFC網路設計前提下,能有效應用於目前有線電視網路系統中,並提供用戶10M~1Gbps以上的高速上網作為解決最後一哩的供裝方案。
本論文最重要的貢獻,除了說明如何將EoC技術應用在HFC網路,亦對EoC相關產品的規格、效能做精確的測試及分析,是利用EoC技術將有線電視現有HFC網路架構,開發最大利用度,進而提昇有線電視業者在媒介經營策略與佈局方面之競爭力。
In this thesis, we cross-examined that EoC could be used to explore the HFC network’s properties, and solve the last mile’s system design problem.
First of all, we build a passive fiber optical network based on FTTB technology. This EPON system is based on external broadband ASE (Amplified Spontaneous Emission) optical source and the optical fiber brag grating. The signal is transmitted from OLT, which connects to the CATV head-end, to the ONU equipment. And then it connects to the new EoC equipment which was placed after the HFC last mile amplifier. Since EoC works in the frequency with high noise-resistance, we can solve the problem caused by Cable modem, i.e. noise transmitted from return path using lower frequency or signal diminishing from using high frequency. We can then provide service to the customers who cannot be served by cable modem.
  From the cross-examination, we can find that EoC technology can be adopted in the current CATV network without altering original HFC network design. And up to 10M~1Gbps bandwidth can be provided to customers as the last-mile broadband service solution.
The most important contribution of this thesis is to explain how EoC technology can be adopted in the HFC network. In addition, we analyze EoC related product’s specifications and efficiency. This will beneficial to cable operators while making the most of HFC networks and increasing the competitiveness in the business operations.
