摘　　要：随着高速交换系统的发展,相干光OFDM(正交频分复用)信号逐渐被应用到AOWC(全光网交换)系统中。仿真实现了在SOA(半导体光放大器)中基于平行双泵浦结构的高速偏振复用OFDM信号的AOWC。从激光相位噪声及SOA注射电流方面对影响系统转换效率的因素进行了分析。仿真结果表明,当光信噪比为18dBm时,转换光的误码率为1.3×10-4,实现了224Gbit/s相干光OFDM转换光信号的无串扰接收。With the development of high speed switching system, coherent Orthogonal-Frequency-Division-Multiplexing （OFDM） signal has been applied to All Optical Wavelength Conversion （AOWC） system. The AOWC of high speed polarization multiplexing OFDM signal based on parallel dual-pump is realized in Semiconductor Optical Amplifier （SOA）. The factors that affect the wavelength conversion efficiency are analyzed theoretically in terms of the laser phase noise and the SOA injec- tion current. When the Optical Signal to Noise Ratio （OSNR） is 18 dBm, the Bit Error Rate （BER） of the converted signal is 1.3×10^-4. The 224 Gbit/s coherent OFDM converted signal can be achieved without crosstalk.
