What is a Passive Optical Network (PON)?
A passive optical network (PON) is a fiber-optic network that allows an Internet service provider (ISP) and consumer to communicate. This is how you get broadband access with fiber-optic services (FiOS). PON is one protocol. Learn more.
What is GPON technology?
GPON (Gigabit Passive Optical Network) is a next-generation PON standard that allows more fiberoptic-coverage and flexibility. Learn more.
What is an ONT used for?
ONT stands for Optical Network Terminal. It is the endpoint device in a fiber to the home (FTTH) or fiber to the business (FTTB) system. Learn more.
What is the Difference Between ONT & ONU?
An optical network terminal (ONT) and optical network unit (ONU) are essentially the same things. The difference is the physical location of the devices, but they function the same in FTTH. Learn more.
Do You Need a Modem with an ONT?
Unlike a cable modem, FiOS does not use DOCSIS. Therefore, on a fiber-optic network you do not need a modem. You need an optical network terminal (ONT). Learn more.
What is the Difference Between OLT and ONT?
OLT stands for Optical Line Terminal. It is you Internet service providers’ (ISP) equipment. ONT stands for Optical Network Terminal. This is the equipment on your end. Learn more about how they fit into your fiber optic network.
ONT: What It Is & How It Works
Learn what an ONT is, how it works with fiber Internet, where it’s installed, and how it differs from a cable modem.
