This paper presents an adaptive equalizer for shorthaul gigabit optical communications. It includes two adaptation loops to compensate the changes in level and spectrum of the input signal. It consumes 29.3 mW for a 1.25 Gb/s signal, transmitted through a 50-m length 1-mm core SI-POF.
We study the tail behavior of discounted aggregate claims in a continuous-time renewal model. For the case of Pareto-type claims, we establish a tail asymptotic formula, which holds uniformly in time.
