%X A novel high spectral efficiency all-optical sampling orthogonal frequency-division multiplexingscheme is proposed using space frequency Block coding (SFBC) techniques and nonlinearbehavior of vertical-cavity surface-emitting laser diodes is exploited by relative intensity to noise(RIN).We show that in long-haul fiber optics communications, SFBC-coded OFDM increasesspectral efficiency and reduces the influence of chromatic dispersion in optical-OFDM system ifRIN is adjusted to -155 dB/Hz
