What is ONU?
ONU equipment is composed of core functional circuits, public units such as power supply and management, and communication interfaces. The core functional blocks include user and service multiplexing functions, transmission multiplexing functions, and ODN interface functions.
The difference between ONU and Switch?
1. ONU: Optical network unit, placed on the user side, an integral part of the EPON network, the other two parts are OLT (optical line terminal), ODN (optical distribution network). The signal sent by the OLT reaches each ONU through the ODN.
2. Switches: ONUs and switches look similar in appearance, especially pure broadband ONUs. The difference is that the ONU can integrate a voice module and use softswitch technology to implement voice communication, while the switch can only open broadband services. In addition, only one optical fiber is required for the ONU uplink, because the EPON network uses wavelength division multiplexing technology to realize single-fiber bidirectional transmission, so there is only one optical port on the ONU; if the switch wants to use optical fiber transmission, it must use two optical fibers.
