Design and Simulation of the AC-coupled Burst-mode receiver with a large time constant

摘要

Due to the Multipoint-to-Point nature of the uplink, the upstream data transmission in a GPON system is burst-mode, and both the guard time and preamble time are short. This burst-mode nature of the GPON uplink brings many challenges for the design of the burst-mode receiver. This paper presents a newly designed AC-coupled burst-mode optical receiver. The AC-coupled receiver uses a large time constant and a high-speed reset switch. The concept of cumulative bit difference of pattern-dependent jitter is also put forwarded in this paper. Finally, simulation results are provided to show the feasibility of the scheme.
