To prepare future gigabit passive optical networks, or GPON, the family of standards is now featuring a new 10 Gbps symmetrical option for operators. Nowadays there are two symmetrical choices in the GPON roadmap for 10 Gbps: XGS-PON (ITU-T G. 1) and NG-PON2. XGS-PON (10-Gigabit Symmetrical Passive Optical Network) is the next-generation fiber optic technology that delivers blazing-fast 10Gbps speeds both upstream and downstream. Its development has undergone continuous evolution and improvement, while also driving the development and popularization of fiber optic access networks. Traditional asymmetric PON technologies (e. It's considered as the ideal solution to FTTx (especially FTTH) with its high bandwidth, great interoperability and manageability, high efficiency, etc, which gains more and more ISPs' favor.
