Penggunaan kuasa unit rangkaian optik (ONU) adalah isu utama dalam rangkaian capaian optik. Penampan hiliran ialah salah satu pengguna kuasa terbesar di kalangan blok berfungsi ONU. Skim tidur kitaran untuk mengurangkan kuasa telah dilaporkan, yang secara berkala mematikan bukan sahaja penimbal hiliran tetapi juga komponen lain, seperti transceiver optik, apabila tempoh melahu adalah panjang. Walau bagaimanapun, apabila tempoh melahu singkat, ia tidak boleh mematikan komponen tersebut walaupun kadar data input rendah. Oleh itu, apabila trafik berterusan, seperti video, meningkat, kesan pengurangan kuasa berkurangan. Untuk menyelesaikan isu ini, kami mencadangkan satu lagi skim tidur di mana penimbal hiliran boleh dimatikan sebahagiannya oleh operasi koperasi dengan terminal talian optik. Hasil simulasi dan percubaan menunjukkan bahawa skim yang dicadangkan mengurangkan penggunaan kuasa ONU tanpa menyebabkan kehilangan bingkai walaupun semasa ONU menerima trafik secara berterusan dan tempoh melahu adalah singkat.

Abstract: The power consumption of optical network units (ONUs) is a major issue in optical access networks. The downstream buffer is one of the largest power consumers among the functional blocks of an ONU. A cyclic sleep scheme for reducing power has been reported, which periodically powers off not only the downstream buffer but also other components, such as optical transceivers, when the idle period is long. However, when the idle period is short, it cannot power off those components even if the input data rate is low. Therefore, as continuous traffic, such as video, increases, the power-reduction effect decreases. To resolve this issue, we propose another sleep scheme in which the downstream buffer can be partially powered off by cooperative operation with an optical line terminal. Simulation and experimental results indicate that the proposed scheme reduces ONU power consumption without causing frame loss even while the ONU continuously receives traffic and the idle period is short.

AB - The power consumption of optical network units (ONUs) is a major issue in optical access networks. The downstream buffer is one of the largest power consumers among the functional blocks of an ONU. A cyclic sleep scheme for reducing power has been reported, which periodically powers off not only the downstream buffer but also other components, such as optical transceivers, when the idle period is long. However, when the idle period is short, it cannot power off those components even if the input data rate is low.
