Chen Zhiqiang1, Yuan Tao1, Tan Zuwei1, et al. Design and realization of burst-mode GPON error testing systems[J]. 2011,(4):8-10. DOI: 10.13756/j.gtxyj.2011.04.011.
the fundamental principle of optical module burst-mode BER tests is described.Based on the characteristics of the upstream data in GPON systems
a novel method and the key technologies for the extraction of burst data are presented and the logic block diagram and time schedule diagrams and circuits for implementing the tests designed.The GPON OLT optical module is tested with this testing system and the results show that this system is featured in simple operation and high reliability and meet the requirements for the test of GPON OLT optical modules.
