提出了一种用于光标签交换的新型混合调制格式--带频移键控标记的差分相移键控。提出了一种基于双并行Mach-Zehnder调制器的调制技术和一种标签擦除方案。通过分析和仿真研究了新格式对高速信道内四波混频的容忍度，表现出对非线性损伤的稳健性。
We propose a novel hybrid modulation format-differential phase shift keying with frequency shift keying labeling for optical label switching. A modulation technique based on a dual-parallel Mach-Zehnder modulator and a label erasing scheme are presented. The tolerance of the new format to intrachannel four-wave mixing at high speeds is studied analytically and through simulations, which show robustness to nonlinear impairments.
