What is GPON (gigabit passive optical network)?

Gigabit Passive Optical Networks (GPON’s) are networks which depend on optical links to convey data. It is regularly utilized to execute the outermost link to the fibre-to-the-premises (FTTP) services user. GPON indicates protocols for error correction and encryption (AES). GPON utilizes the Advanced Encryption Standard (AES) for security reasons, which was intended to be effective in both hardware and software, and it assists with a block length of 128 bits and key lengths of 128, 192, and 256 bits.
