What It Means
GPON is the standard behind most fiber broadband deployments from AT&T, Verizon FiOS, Google Fiber, and regional ISPs. A single optical line terminal (OLT) at the provider's central office connects to an optical splitter, which divides the signal to serve multiple homes. Each home gets an Optical Network Terminal (ONT) that converts light signals to ethernet. While the 2.5 Gbps bandwidth is shared, real-world speeds typically reach 900 Mbps-1 Gbps per home. XGS-PON, the next generation, supports 10 Gbps symmetrical.
