我们提出并实验证明了一个80 Gbits/s的偏振复用归零差分相移键控信道利用窄带光滤波器和低速检测器的光信噪比（OSNR）监测技术。在250 MHz的射频（rf）下测量的最大功率增量为19.7 dB，用于监测高达27 dB的OSNR，对0-300 ps/nm的色散和0-50 ps的偏振模色散（PMD）不敏感。(C)2009年美国光学学会
We propose and experimentally demonstrate an optical signal-to-noise ratio (OSNR) monitoring technique for an 80 Gbits/s polarization-multiplexed return-to-zero differential phase-shift keying channel utilizing a narrowband optical filter and a low-speed detector. A maximum power increment of 19.7 dB is measured at a radio frequency (rf) of 250 MHz for monitoring of OSNR up to 27 dB, insensitive to chromatic dispersion of 0-300 ps/nm and polarization-mode dispersion (PMD) of 0-50 ps.
