| Abstract: | In view of the characteristics of PHY(physical layer) in optical LAN(local area network), an on line method for Q factor detection based on DSP(digital signal processor) technology is put forward and its mathematical physical model is discussed. A series of simulative tests indicate that the method is valid, feasible, and convenient. |
