The received waveform monitoring part (1) has a waveform monitoring circuit (2) that samples data from the received waveform of a received signal having propagated along a transmission path, and a histogram extracting circuit (3) that extracts, based on the sampled data obtained by the waveform monitoring circuit (2), a histogram data representative of the intensity distribution in the voltage direction of the received waveform. The dispersion amount determining part (4) has a polarized wave dispersion estimating circuit (7) that determines the horizontally asymmetric degree of a received eye-pattern waveform of the received waveform obtained by analyzing the histogram data extracted by the received waveform monitoring part (1) and then estimates, based on the determined asymmetric degree, a polarized wave dispersion amount in the transmission path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dispersion determining apparatus and automatic dispersion compensating system using the same","description":"A dispersion determining apparatus comprises a received waveform monitoring part (1) and a dispersion amount determining part (4).
