What does onu equipment mean?

ONU means optical node. ONU equipment is usually explained as an optical fiber equipped with equipment including optical receivers, upstream optical transmitters, and multiple bridge amplifier network monitoring equipment. node.

ONU equipment consists of core functional circuits, common units such as power supply and management, and communication interfaces. The core functional blocks of ONU include user and service multiplexing functions, transmission multiplexing functions, and ODN interface functions.

The user and service multiplexing function of ONU equipment includes assembling information from each user, allocating information to be transmitted to each user, and connecting a single service interface function; the transmission multiplexing function includes analyzing the signal coming from the ODN And take out the part belonging to the ONU and reasonably arrange the information to be sent to the ODN.

ONU: refers to the optical network equipment connected to the branch optical fiber of the ODN.

ONU is divided into active optical network unit and passive optical network unit. Generally, equipment equipped with network monitoring devices including optical receivers, uplink optical transmitters, and multiple bridge amplifiers are called optical nodes.

ONU is the user-side device of the GEPON (Gigabit Passive Optical Network) system, which is used to terminate services transmitted from the OLT (Optical Line Terminal) through the PON (Passive Optical Network). Cooperating with OLT, ONU can provide various broadband services to connected users.

Such as Internet surfing, VoIP, HDTV, and other services. As the user-side equipment for FTTx applications, ONU is a high-bandwidth and cost-effective terminal equipment necessary for the transition from the "copper cable era" to the "optical fiber era".

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 user and service multiplexing function includes assembling information from each user, allocating information to be transmitted to each user, and connecting a single service interface function; the transmission multiplexing function includes analyzing the signal coming from the ODN and extracting the part of the ONU and reasonably arranges the information to be sent to the ODN; the ODN interface function provides a series of optical physical interface functions, including optical/electrical and electrical/optical conversion.
