GPON is comprised of three primary components: an Optical Line Terminal (OLT), an Optical Network Unit (ONU) device, and a passive splitter. There are no specific requirements for this document. This document is not restricted to specific software and hardware versions. The information in this document was created from the devices in a. GPON is a passive point-to-multipoint optical network that shares a fiber among dozens of users through splitters. The OLT manages GTC frames, TDMA and AES encryption to coordinate OLT–ONT, guaranteeing bandwidth and security. It offers download speeds of up to 2,5 Gbit/s and upload speeds of up to. ITU-T G. It converts data signals, manages bandwidth, and connects hundreds of users over a single optical fiber infrastructure.
