Research Article


This paper proposed and investigated a novel frequency shift keying (FSK) modulation based on two fiber Bragg gratings (FBGs) and two intensity modulators. Then the transmission of 10 Gbit/s FSK signal after a 50 km single mode fiber (SMF) was studied in this paper. The power penalty at the bit error rate (BER) of 10–9 was below 0.1 dB. The FSK modulation system can be applied to optical transmission system
