            Abstract : 
We describe the effect of a finite-decision ambiguity level on optical receiver sensitivity. A new analytic expression for the receiver sensitivity including the effect of the decision ambiguity level is obtained by modifying the well-known expression assuming an ideal decision circuit. Also obtained is a requirement for linear channel transimpedance gain or decision ambiguity level for less than 1-dB power penalty of receiver sensitivity.<>
