Abstract	Abstract — We propose a new simple method to achieve precise symbol synchronization using one start-of-frame (SOF) symbol in optical fast orthogonal frequency division multiplexing (FOFDM) with sub-channel spacing equal to half of the symbol rate per sub-carrier. The proposed method firstly identifies the SOF symbol, then exploits the evenly symmetric property of the discrete cosine transform in FOFDM, which is also valid in the presence of chromatic dispersion, to achieve precise symbol synchronization. We demonstrate its use in a 16.88Gbit/s phase shifted keying based FOFDM system over a 124km field-installed single-mode fiber link and show that this technique operates well in automatic precise symbol synchronization at an optical signal-to-noise ratio as low as 3dB and after transmission. Index Terms — Modulation, orthogonal frequency division multiplexing, wavelength division multiplexing, detection
