Abstract :
An optical OFDM system with constellation fine adjustment scheme is proposed and experimentally demonstrated. The complexity of the scheme is analyzed and proved to be acceptable. The single-mode fiber transmission distance of a 56Gb/s O-OFDM system is successfully extended by 350-km at the FEC limit with less reference symbols added.
