摘要
实验验证了应用中点谱反转技术实现155 Mb/s～10 Gb/s频移键控/幅度调制(FSK/IM)正交信号的100 km传输。其中,FSK/IM正交信号的频谱反转由基于半导体光放大器(SOA)的四波混频效应实现,此技术有效克服了FSK/IM正交信号在传输中色散带来的影响。实验采用DFB激光器作光源,康宁公司生产的标准单模光纤作传输链路,采用长为1.5 mm,光限制因子为0.15的半导体光放大器实现频谱反转。实验中固定FSK/IM的中心波长,测试了接收端FSK与IM信号的眼图,结果发现,标记FSK与数据包IM的性能良好。
Abstract
155 Mb/s～10 Gb/s orthogonal FSK/IM signal’s transmission over 100 km of standard fiber based on mid-span spectral inversion is experimentally demonstrated. The phase-conjugation is achieved by four-wave mixing in an optimized semiconductor optical amplifier (SOA), which solves the dispersion problem of the FSK/IM orthogonal signal. We use the DFB laser as the optical source, and take the Corning’s standard single-mode fiber as transmission link, and adopt the SOA with 500 μm length, and 0.15 optical confinement factor to realize spectral inversion. In the experiment, the central wavelength of orthogonal FSK/IM signal is fixed. We get the eye diagrams of the packet (label) in the IM (FSK) receiver. The results prove that the system has a good performance.
