We demonstrate high-speed optical frequency-shift-keying (FSK) transmission over a 95 km single-mode fiber (SMF) at 10 Gbit/s using a LiNbO3 optical FSK modulator and an optical interleaver. The measured eye diagrams, bit error rate (BER) performances and optical spectrum indicate the FSK modulation is similar to zero chirp non-return-to-zero (NRZ) on-off-keying (OOK) transmission. Therefore, in view of dispersion tolerance, the FSK modulation can be treated as well as NRZ OOK.
