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 <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω</em><sub>0</sub>) = 1 - <em>H<sub>n</sub></em>(<em>jω</em>/<em>ω</em><sub>0</sub>) is proposed, of which better performance is anticipated than that of conventional AC-coupling. Next, an optical burst mode receiver with fast response <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω<sub>F</sub></em>) and slow response <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω<sub>S</sub></em>), whereby <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω<sub>F</sub></em>) switches to <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω<sub>S</sub></em>) right after the DC component of the input burst signal converges to 0 is proposed. Then, an automatically switching circuit that switches fast response <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω<sub>F</sub></em>) to slow response <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω<sub>S</sub></em>) circuits right after the maximum peak value of the output burst <em>G<sub>n</sub></em>(<em>jω</em>/<em>ω<sub>F</sub></em>) 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.
