Abstract :
We verify an insertion effect of cyclic prefix for reduction of inter channel interference in all-optical fractional OFDM system. Since fractional OFDM has an intermediate characteristic between OFDM and Nyquist-OTDM, a certain degree of effect of cyclic prefix is expected in fractional OFDM. The results of bit error rate measurement of a 4×10 Gbit/s DBPSK all-optical fractional OFDM system show that cyclic prefix improves the signal quality under an insufficient time gate condition.
