  • Abstract
    An asynchronous sampling monitor for optical DPSK signals by using a two-tap histogram is proposed. By means of statistical analysis, a parameter is defined to measure the Q-factor to indicate the OSNR degradation. Compared to traditional monitoring methods, this method requires no synchronisation before sampling and is thus cost-effective.
