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 principle
network architecture and key technologies.Then it studies and analyzes OFDM-PON-based services and bandwidth scheduling 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.
