Abstract

We have performed a mathematical analysis to derive the inherent transmission capacity penalty of burst-mode optical receivers due to the finite holding time constant /spl tau//sub f/ of the adaptive threshold control circuit. The fundamental degradation of the system depends on a decay parameter k. For capacity penalty calculation, we propose a criterion that k/spl les/0.25 for encoded data. The transmission capacity penalty /spl beta/ of the network is given by /spl beta/=1/(1+kN/m/spl times/ln/spl alpha//sub N/), where N is the number of bits in one packet, /spl alpha//sub N/ is the dynamic range of the receiver, and m is the maximum number of consecutive "0"s in the data pattern. When the data stream is encoded with 4B5B or 5B6B, the capacity penalty is about 12% for ATM packets (424 bits) independent of the bit-rate.<>
