The ONU in EPON adopts the mature technology Ethernet protocol, which can realize low-cost Ethernet layer 2 and layer 3 switching functions. This kind of ONU can provide shared high bandwidth for multiple end users through cascading. In the communication process, no protocol conversion is needed, and the transparent transmission of user data can be realized. ONU also supports other traditional TDM protocols without increasing the complexity of design and operation.
The OLT and all ONUs in EPON are managed by the network element management system, and the network element management system provides the operating interface with the core network of the service provider. The scope of network element management involves fault management, configuration management, billing management, performance management, and security management.
working principle:
1. Downstream data stream uses time division multiplexing (TDM) technology
During the transmission of the EPON signal, the downstream data is broadcast from the OLT to multiple ONUs. According to the IEEE802.3 protocol, the length of these data packets is variable, and the longest can reach 1518 bytes. Each data packet has its own destination address information, that is to say, the header of each packet indicates whether the data is for ONU1, ONU2 or ONUn. In addition, some packets can be sent to all ONUs, called broadcast packets, and some are sent to a special group of ONUs, called multicast packets. The data stream is divided into n independent signals after passing through the Optical Splitter, and each signal contains all specific data packets. When the ONU receives the data stream, each ONU extracts the data packets destined for itself according to the specific address information, and discards those data packets with different address information.
2. Upstream data flow uses time division multiple access (TDMA) technology
During the transmission of the EPON signal, the upstream data is sent from multiple ONUs to the OLT in a time division multiple access mode. Each ONU is assigned a transmission time slot. These time slots are synchronized. Therefore, when data packets are coupled to an Optical Fiber, different ONUs will not cause interference. For example, ONU1 transmits data packet 1 in the first time slot, ONU2 transmits data packet 2 in the second unoccupied time slot, and ONUn transmits data packet n in the nth unoccupied time slot, so that transmission conflicts can be avoided.
