A PON system is made up of an OLT and ONT and is considered passive because it is a point-to-multi-endpoint system served by unpowered splitters. Using a single cable and delivering more than just Internet access are some of the key advantages of PON fiber Internet over others.

Jan 1, 2022 · EPON OLT (optical line terminal) is a device that acts as the service provider endpoint of a passive optical network. It connects to the Ethernet switch and ONU.

GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Optical Network) are both PON protocols that serve Ethernet acces to users over a fiber-optic network. Learn more about the difference and how they work.

Dec 5, 2023 · The EPON Optical Line Terminal (OLT) is the backbone of an EPON network and is responsible for subscriber management, traffic aggregation, QoS control, and network monitoring. Understanding the role of the EPON OLT is important for those involved in deploying and managing EPON networks.

Mar 14, 2023 · ONT is an ITU-T term, whereas ONU is an IEEE term. Belonging to different standard bodies, they both denote user-side equipment in the EPON system. However, in practice, there is a slight difference between ONT and ONU based on their location.

Jan 17, 2025 · EPON typically supports splitter ratios from 1:16 to 1:128. So EPON OLTs can support more EPON ONUs. However, as the splitter ratio increases, the transmission distance decreases due to higher insertion losses, making EPON less …

May 13, 2015 · In a Gigabit Ethernet Passive Optical Network (GEPON) system, there are an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) or optical network terminals (ONTs) near …

Jun 3, 2023 · OLT is short for optical line terminal, which is a device used to connect optical fiber and transfer signals. OLT is the starting point for the PON, which is connected to an aggregation switch through Ethernet cables.

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.

May 9, 2023 · This article explains the basic concept and functions of OLT in EPON, GPON, 10G EPON, and 10G GPON networks.
