Select to receive broadcast data sent by the OLT; 2. Respond to the ranging and power control commands issued by the OLT; and make corresponding adjustments; 3. The user's Ethernet data is buffered and sent in the upward direction in the transmission window allocated by the OLT. ODN (optical distribution network) Optical distribution network is an FTTH optical cable network based on PON equipment. Its role is to provide an optical transmission channel between the OLT and the ONU. From the functional point of view, the ODN can be divided into four parts: the feeder line subsystem, the wiring system, the subscriber line cable subsystem and the fiber terminal subsystem.

In the 3G era, each person's monthly average 300M traffic is about ten times that of the past. Because there are more applications at this time; in the current 4G, the required traffic is not as simple
