Что такое EPON (GEPON) 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 Unit (ONU) near end users.
 

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.
