摘　　要：An optical frequency shift keying(FSK) transmitter performed by the cross gain modulation(XGM) in a semiconductor optical amplifier(SOA) is used in an optical label switching(OLS) system with 622 Mbit/s FSK label and 10 Gbit/s amplitude shift keying(ASK) payload.The key parameters in this system are optimized to achieve the best performance of FSK/ASK signal,including the input power of LD,the extinction ratio(ER) of the control light and that of the ASK payload.Besides,the transmission performance of ASK payload and FSK label is also investigated after propagating in the 50 km single-mode fiber(SMF).An optical frequency shift keying（FSK） transmitter performed by the cross gain modulation（XGM） in a semiconductor optical amplifier（SOA） is used in an optical label switching（OLS） system with 622 Mbit/s FSK label and 10 Gbit/s amplitude shift keying（ASK） payload.The key parameters in this system are optimized to achieve the best performance of FSK/ASK signal,including the input power of LD,the extinction ratio（ER） of the control light and that of the ASK payload.Besides,the transmission performance of ASK payload and FSK label is also investigated after propagating in the 50 km single-mode fiber（SMF）.
