“…However, such high-speed optical signals are more vulnerable to some optical system impairments such as fiber chromatic dispersion, polarization mode dispersion, and fiber nonlinearity. Therefore, more advanced optical signal processing techniques are required to characterize the signal quality and assure the transmission performance of such high-speed optical signals in various kinds of modulation formats [4,5] .…”

In an optical performance monitoring system for high-speed optical communications, the ultra-short optical pulse from the laser is divided into two parts. One is to sample high-speed optical communication signal and the other as the sampling clock in an analog/digital converter (ADC) after detecting using a photon-detector. We propose a simple method based on variance calculation to align the phase of sampling clock in an ADC. The experiments demonstrate that, with the proposed method, the eye diagram or constellation diagram of high-speed optical communication signal can be reconstructed by the optical performance monitoring system.
