OFDM signal transmitting apparatus and method for OFDM-PON

摘要

Disclosed is a method and apparatus for transmitting orthogonal frequency division multiple signals in an optical subscriber network. An orthogonal frequency division multiple signal transmission method in an optical subscriber network according to an embodiment of the present invention is a medium access transmitted from a media access control layer of a passive optical subscriber network to a physical layer of a passive optical subscriber network based on an orthogonal frequency division multiplexing method. And converting the medium access control frame into an orthogonal frequency division multiple frame including a physical level preamble using the control frame, and transmitting the transformed orthogonal frequency division multiple frame.
