EPON (Ethernet Passive Optical Network), as the name suggests, is a PON technology based on Ethernet. It adopts point-to-multipoint structure, passive optical fiber transmission, and provides multiple services on Ethernet. EPON technology is standardized by the IEEE802.3 EFM working group. In June 2004, the IEEE802.3EFM working group released the EPON standard-IEEE802.3ah (incorporated into the IEEE802.3-2005 standard in 2005). In this standard, the Ethernet and PON technologies are combined, the PON technology is used in the physical layer, the Ethernet protocol is used in the data link layer, and the PON topology is used to realize Ethernet access. Therefore, it combines the advantages of PON technology and Ethernet technology: low cost, high bandwidth, strong scalability, compatibility with existing Ethernet, and convenient management.
ONU (Optical Network Unit) optical network unit, ONU is divided into active optical network unit and passive optical network unit. Generally, devices equipped with network monitoring including optical receivers, upstream optical transmitters, and multiple bridge amplifiers are called optical nodes. The PON uses a single optical fiber to connect to the OLT, and then the OLT connects to the ONU. ONU provides services such as data, IPTV (i.e. interactive network television), and voice (using IAD, i.e. Integrated Access Device), truly realizing "triple-play" applications.
