What are EPON OLT and EPON ONU?
Ethernet Passive Optical Network (EPON), defined by IEEE 802.3ah, is a point to multipoint (Pt-MPt) network topology implemented with passive optical splitters, along with optical fiber PMDs that support this topology.
EPON is based upon a mechanism named MPCP (Multi-Point Control Protocol), which uses messages, state machines, and timers, to control access to a P2MP topology.
A EPON network consists of an Optical Line Terminal (OLT) at the service provider’s central office and a number of Optical Network Units (ONUs) near end users.
EPON OLT, also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions:
- To perform conversion between the electrical signals used by the service provider’s equipment and the fiber optic passive component signals used by the passive optical network.
- To coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).
EPON ONU, optical network unit is a device that transforms incoming fiber optic passive component optical signals into electronics/terminals at a customer’s premises in order to provide telecommunications services over an optical fiber network.
