Lightem LGPONU-1RJ45 is one of the GPON optical network unit design to meet the requirement of the broadband access network. It apply in FTTH/FTTO to provide the data and video service based on the GPON network. It is based on ZTE high-performance xPON access chip. The chip supposes three mode: GPON/EPON/P2P, comply with the GPON standard of g.984, g.983, 802.3-2005, CTC EPON equipment technical requirements, have good xPON interoperability compatibility. It provide one GE auto-adapting Ethernet ports. The LGPONU-1RJ45 features high-performance forwarding
capabilities to ensure excellent experience with Internet and HD video services. Therefore, it provides a perfect terminal solution and future-oriented service supporting capabilities for FTTH deployment. It has good third-party compatibility to work with the OLT.
