Application scenario

XP3210 is applied to the integrated access of the edge side of the power system, supporting remote information collection and transmission. In the PON network, two PONs are used to uplink to different OLTs, playing the role of network protection; In the Ethernet network environment, the ERPS ring network is formed through dual GE, and the network protection function is achieved through ring switching protection. At the same time, in the case of cable network failure, the 4G/5G LTE network can also be used as an emergency backup to inform the failure in time for remote management and maintenance; The downlink is connected to switching station, ring network cabinet, power distribution room and other equipment through GE and serial port.

The ONU adopts the "hand in hand" full protection switching type high reliability topology, and the 1+1 protection function of the power grid communication link and realizes the protection switching of less than 50ms to ensure the reliable operation of the power grid communication system. Support single/dual home service protection of TYPE B and TYPE C. In addition, according to the actual distribution network structure, the tree, chain handle, ring and other structures can also be flexibly adopted.

Multiple network access

It can support GPON/EPON adaptation to meet different network building requirements. The device can flexibly select GPON/EPON passive optical network.

Support 4G/5G LTE backup of wireless wide area network. In case of wired network failure, it can quickly switch to wireless network to ensure smooth network and facilitate remote management and unattended. Special scenarios can also support 4G/5G service access to facilitate network deployment.
