The document discusses two series of ONU transceivers for next generation PON networks: the EOLS-PX-GU-20 series compliant with ITU-T G.987.2 XGPON N2a and the EOLS-PR-GU-20 series compliant with ITU-T G.9801.1 XGS-PON. Both series are single fiber bi-directional transceivers in an SFP+ package with SC receptacle and single +3.3V power supply. The key differences are that the XGPON N2 series provides 2.488Gbps upstream and 9.95Gbps downstream transmission, while the XGS-PON series provides symmetrical
