摘要
OFDM-PON(正交频分复用无源光网络)是目前光接入网研究热点之一。文章简述了OFDM-PON技术的研究背景,阐明了OFDM-PON的技术原理、网络架构和关键技术,对基于OFDM-PON的业务及带宽调度进行了研究分析,并对OFDM-PON技术的应用前景进行了展望。研究表明,与传统的PON相比,OFDM-PON系统不仅传输带宽大幅度提升,而且可以实现基于子载波、调制格式和时间的三维业务及带宽调度。
The Orthogonal Frequency-Division Multiplexing Passive Optical Network （OFDM-PON） technology is one of the current research focuses in optical access networks. This paper first briefly describes its study background, explains its princi- ple, network architecture and key technologies. Then it studies and analyzes OFDM-PON-based services and bandwidth sched- uling and predicts the prospects of its applications. Study results show that compared with the conventional PON systems, OFDM-PON system has its transmission bandwidth dramatically increased and realizes subcarrier-, modulation format-, and time slot-based services and bandwidth scheduling.
