ONU equipment is composed of core functional circuits, power supply and management and other common units and communication interfaces. The core functional blocks of ONU include user and service multiplexing functions, transmission multiplexing functions, and ODN interface functions. User and service multiplexing functions include assembling information from each user, allocating information to be transmitted to each user, and connecting a single service interface function; transmission multiplexing function includes analyzing the signal from the ODN and extracting the part belonging to the ONU and reasonable The information to be sent to the ODN is arranged locally; the ODN interface function provides a series of optical physical interface functions, including optical/electrical and electrical/optical conversion.
If each ONU uses more than one optical fiber to connect to the ODN, then there is more than one physical interface. The ONU service function block provides user-side functions, which includes providing user service interfaces and adapting user information to the form of 64kbit/s or n×64kbit/s; this function block can serve one or several users and can be based on The physical interface provides signaling conversion function. ONU general function blocks provide power supply functions and system operation, management and maintenance (OAM) functions. The power supply function includes AC to DC or DC to AC, and the power supply mode is local power supply or remote power supply. Several ONUs can share a power supply. ONUs should also work normally when powered by a backup power supply.
