EPON type equipment
For TDM-PON, a passive optical splitter is used in the optical distribution network. In the upstream direction, each ONU (optical network units) or ONT (optical network terminal) burst transmits for an assigned time-slot (multiplexed in the time domain). PON (Passive Optical Network), as an access network technology, can implement fiber optic to the home, satisfying the high-bandwidth requirement of the "last kilometer" in the access layer network. While GPON dominates in Europe, EPON is the reference standard in Asia—Japan, South Korea, and China—and remains present.
