ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING ACCESS-PASSIVE OPTICAL NETWORK COMPRISING OPTICAL NETWORK UNIT AND OPTICAL LINE TERMINAL

摘要

Disclosed is a technology for an orthogonal frequency division multiple access-passive optical network. The orthogonal frequency division multiple access-passive optical network, according to an embodiment of the present invention, includes a plurality of optical network units, each of which is configured to generate orthogonal frequency division multiplexed signals allocated based on a central frequency for frequency division multiplexing allocated in advance; and uses the generated signals in upstream transmission.
