2 1.1 Overview The Ethernet passive optical network (EPON) series products released by H3C include optical line terminal (OLT) devices and optical network unit (ONU) devices (EPON is a passive optical network implementation). By using optical splitters, Aolynk ET series ONU devices, and H3C S7500 series switches with the OLT (optical line terminal) function, you can set up EPONs to provide various optical accessing solutions, such as fiber to the home (FTTH) and fiber to the building (FTTB). In these optical accessing solutions: The OLT devices can be H3C S7500 series Ethernet switches. The ONU devices can be Aolynk ET series optical terminals or H3C S3100 series Ethernet switch with the ONU function. Note: For information about Aolynk ET series optical terminals and H3C S3100 series Ethernet switches with ONU functions, see Aolynk ET Series EPON ONU Quick Start and H3C S3100 Series Ethernet Switches Quick Start System Description and Application OLT devices can be deployed in the center office. As for the user side, you can use different ONU devices for different optical access solutions. OLT devices and ONU devices can be connected in the point-to-multipoint mode using POSs. FTTB solution: Deploy the ONU devices (H3C S3100 series with the ONU functions) beside the power distribution box in a basement or connect ET300/ET300-L20 to the switch in the corridor, and then perform networking configuration based on actual requirements. 1-1
