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.

Key words: quality of service, DSP, LAN, Q factor, on-line detection
