Characteristic evaluation of 20-Bit consecutive codes in high performance optical burst mode receiver configuration

Abstract

Optical burst mode receivers are indispensable components for Passive Optical Network (PON) and Ethernet Optical Access Network (E-OSAN). An optical burst mode receiver with transfer function G_n(jω/ω₀) = 1 - H_n(jω/ω₀) is proposed, of which better performance is anticipated than that of conventional AC-coupling. Next, an optical burst mode receiver with fast response G_n(jω/ω_F) and slow response G_n(jω/ω_S), whereby G_n(jω/ω_F) switches to G_n(jω/ω_S) right after the DC component of the input burst signal converges to 0 is proposed. Then, an automatically switching circuit that switches fast response G_n(jω/ω_F) to slow response G_n(jω/ω_S) circuits right after the maximum peak value of the output burst G_n(jω/ω_F) is 1/2 and the DC components of the input burst converges to 0 is also proposed. This paper presents the experiments on same consecutive codes in burst mode receivers using the proposed automatically switching circuit, with evaluation on its characteristics made through simulation.
