摘要：
We analyze the signal-signal beating interference (SSBI) when optical orthogonal frequency division multiplexing (OOFDM) signal is directly detected by photodiode at the receiver. We propose a novel training sequence configuration to reduce SSBI. The experimental results show that the receiver sensitivity of the OFDM signal with the new training sequence at the BER of 1 x 10(-3) is 2.4 dB better than that with standard training sequence after transmission over 100 km standard single mode fiber (SSMF) at a bit rate of 2.5 Gbit/s.
