Walaupun rangkaian optik pemultipleksan-pasif pembahagian panjang gelombang (WDM-PON) dikenali sebagai pemindahan berkelajuan tinggi, ia menghasilkan kos saluran yang tinggi bagi setiap pelanggan dan penggunaan lebar jalur yang rendah disebabkan fakta bahawa panjang gelombang dikhaskan untuk setiap pelanggan. Oleh itu, adalah penting untuk mengurangkan kos saluran bagi setiap pelanggan dan meningkatkan penggunaan lebar jalur. Untuk mencapai matlamat ini, kami mula-mula mengguna pakai WDM-PON sedia ada, yang menggunakan penghantaran dua arah dengan satu sumber untuk kecekapan kos dengan menggunakan penguat optik semikonduktor reflektif tepu tepu (RSOA). Kedua, berdasarkan WDM-PON sedia ada, kami mencadangkan WDM/TDM-PON hibrid yang dipertingkatkan, yang boleh memanjangkan bilangan pelanggan yang disokong dalam setiap panjang gelombang dengan pembahagi dalam lapisan fizikal dan format bingkai dupleks pembahagian masa kongsi (TDD). dalam lapisan kawalan akses media (MAC). Selain itu, ia boleh mengawal lebar jalur secara adaptif melalui skim peruntukan lebar jalur dinamik (DBA) mengikut volum trafik. Berbanding dengan WDM/TDM-PON hibrid bukan berasaskan TDD, ia boleh mengurangkan kos saluran bagi setiap pelanggan daripada bilangan lanjutan pelanggan yang disokong dalam setiap panjang gelombang. Tambahan pula, disebabkan oleh DBA, ia boleh meningkatkan jumlah kelewatan dan daya pemprosesan baris gilir, dan dengan itu meningkatkan penggunaan lebar jalur.

Abstract: Although wavelength division multiplexing-passive optical network (WDM-PON) is known as a high-speed transfer, it creates high channel costs per subscriber and low bandwidth utilization due to the fact that a wavelength is dedicated to each subscriber. Thus, it is imperative to reduce channel costs per subscriber and improve the bandwidth utilization. To achieve these, we first adopt a existing WDM-PON, which uses the bidirectional transmission with a single source for cost-efficiency by employing a gain-saturated reflective semiconductor optical amplifier (RSOA). Secondly, based on the existing WDM-PON, we propose an enhanced hybrid WDM/TDM-PON, which can extend the number of subscribers supported in each wavelength with splitters in the physical layer and a shared-time division duplex (TDD) frame format in the media access control (MAC) layer. Moreover, it can adaptively control the bandwidth through a dynamic bandwidth allocation (DBA) scheme according to the volume of traffic. Compared to the non TDD-based hybrid WDM/TDM-PON, it can reduce channel costs per subscriber from the extended number of subscribers supported in each wavelength. Furthermore, due to the DBA, it can improve the total queueing delay and throughput, and thus increase the bandwidth utilization.
