Penyepaduan sistem capaian gentian optik adalah kunci untuk menyediakan pelbagai jenis perkhidmatan kepada pengguna rumah. Gabungan sistem ATM dan SCM-PON adalah penting untuk menyokong perkhidmatan data berkelajuan tinggi dan perkhidmatan pengedaran video analog/digital. Dari sudut pandangan ini, teknik pemultipleksan pembahagian frekuensi untuk jalur asas digital dan isyarat pemultipleks subcarrier diperlukan untuk mencapai penyepaduan sistem. Walau bagaimanapun, penyepaduan sistem untuk kedua-dua sistem capaian ini belum lagi disiasat sepenuhnya. Sistem SCM-PON, yang menggunakan penukar FM optik jalur lebar super, akan membolehkan dua jenis sistem capaian (ATM dan SCM) yang berbeza ini disepadukan. Dalam makalah ini, kami menghuraikan keputusan yang diperoleh secara eksperimen untuk isyarat berbilang pembahagian frekuensi yang terdiri daripada isyarat berbilang jalur asas digital dan isyarat berbilang pembawa. Eksperimen telah dijalankan menggunakan isyarat jalur asas 622-Mb/s dan isyarat ditukar FM yang mengandungi isyarat AM dan 64QAM. Keputusan eksperimen mendedahkan bahawa gangguan antara saluran antara jalur asas digital dan isyarat ditukar FM mengehadkan bilangan subpembawa untuk AM dan 64QAM. Dengan frekuensi perantaraan 3 GHz untuk isyarat ditukar FM, isyarat FDM yang terdiri daripada jalur asas 622-Mb/s, 30 pembawa 64QAM dan 11 pembawa AM berjaya dihantar.

Abstract: Fiber-optic access system integration is the key to providing various kinds of services to home users. The combination of ATM- and SCM-PON systems is essential to support a high-speed data service and analog/digital video distribution services. From this viewpoint, a frequency-division- multiplexing technique for digital baseband and subcarrier multiplexed signals is required to achieve system integration. However, system integration for these two access systems has not been fully investigated yet. The SCM-PON system, which uses a super wideband optical FM converter, will enable these two different kinds of access system (ATM and SCM) to be integrated. In this paper, we describe experimentally obtained results for frequency- division-multiplexed signals consisting of digital baseband and subcarrier- multiplexed signals. The experiments were carried out using a 622-Mb/s baseband signal and an FM-converted signal containing AM and 64QAM signals. The experimental results reveal that the inter-channel interference between the digital baseband and FM-converted signals restricts the number of subcarriers for AM and 64QAM. With an intermediate frequency of 3 GHz for the FM-converted signal, an FDM signal consisting of 622-Mb/s baseband, 30 carriers of 64QAM, and 11 carriers of AM was successfully transmitted.
