QU Zi-jing, DAI Qi-wei, SUN Li-ping, et al. The Key Technology of the Upstream BM-Receiver in XGPON[J]. 2018,(3):21-24. DOI: 10.13756/j.gtxyj.2018.03.006.
The paper elaborate the key technology of 2.5 Gbit/s Burst Mode(BM)receiver for the 10 Gbit/s Passive Optical Network(XGPON)in the Optical Line Terminal(OLT)side.For the purpose of improving the performance of receiver
we apply an automatically method to adjust the frequency domain characteristics of the circuit
and design a receiving circuit which can establish the synchronization of the received signal in a very short time slot with high sensitivity.
