GPON stands for Gigabit Passive Optical Network
It is a type of high-speed network standard for Internet access, mainly used for broadband services over optical fiber. Here are the details of GPON and its main features: 1. Network Structure: GPON is based on point-to-multipoint architecture, which means that a single fiber optic cable can serve multiple locations using passive optical splitters. This is in contrast to the point-to-point model, where each location requires its own fiber optic cable. 2. OLT and ONT/ONU: OLT (Optical Line Terminal): This is a device located at the service provider's headquarters. It transmits data to multiple users and also collects data from users. ONT (Optical Network Terminal) or ONU (Optical Network Unit): This is a device located at the customer's premises. It receives data sent from the OLT. The terms ONT and ONU are sometimes used interchangeably, but ONT is usually customer facing and ONU can refer to a larger device that serves multiple customers in some situations. 3. Sp...
