The optical network unit (ONU) is a terminal device for Optical Fiber access. It should be used in conjunction with an OLT (Optical Line Terminal). The OLT generally stores the central computer room of the ISP.
The optical network unit is an optical fiber termination device in the optical fiber access network, which provides multiple service interfaces to users. It has an optical interface on the network side and an electrical interface on the user side. Therefore, the optical network unit (ONU) needs to have the functions of optical/electrical conversion and electric/optical conversion, as well as digital/analog and analog-to-speech signals. /Digital conversion function and multiplexing, signaling processing and maintenance management functions.
Generally speaking, the functions of the optical network unit mainly include the following items
1. Choose to receive the broadcast data sent by the OLT;
2. Respond to the ranging and power control commands sent by the OLT; and make corresponding adjustments;
3. Buffer the user's Ethernet data and send it to the upstream in the sending window allocated by the OLT
