10G EPON almost completely inherits the existing EPON standard and follows the IEEE 802.3ah MPCP protocol of EPON to the maximum extent, only expanding the upstream and downstream bandwidth of 802.3ah standard to reach 10G rate; It has good compatibility with the EPON network. The ONU of 10G EPON can share an ODN with the…

EPON (Ethernet Passive Optical Network) is a new type of optical access network technology. It uses a point-to-multipoint structure and passive optical fiber transmission to provide multiple services over Ethernet. It uses PON technology in the physical design and Ethernet protocol in the data link layer to realize Ethernet access by using the topology of…

GPON (Gigabit Capable PON) technology is the latest generation of broadband passive optical integrated access technology based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, rich user interfaces, etc. It is regarded by most operators as an ideal technology to realize broadband and integrated transformation of access network…

XGPON could also be called 10G GPON. The bandwidth of XGPON is asymmetric between uplink and downlink, with 2.5Gbps for uplink and 10Gbps for downlink, the spectral ratio is 1:128. With the same spectral ratio, the maximum transmission distance of XGPON can reach 40KM. XGPON wavelength planning and GPON wavelength planning do not overlap, so…

XGS-PON and XG-PON both belong to the GPON series. XGS-PON is the technological evolution of GPON and XG-PON, supporting the mixed access of GPON, XG-PON, and XGS-PON ONU. XG-PON and XGS-PON are both 10G PON. The main difference is that XG-PON is an asymmetric PON, and the uplink/downlink rate of the PON port is 2.5G/10G;…
