broadband services using passive splitters and optical fiber. The OLT (Optical Line Terminal) is the central device in a GPON network.

It connects the service provider’s core network to multiple ONUs/ONTs (Optical Network Units/Terminals) located at the customer’s premises. In simple terms, the OLT acts as the brain of the GPON system, managing traffic, authentication, bandwidth allocation, and service delivery.

A 16 Port GPON OLT means the device has 16 GPON ports, each capable of connecting multiple subscribers through optical splitters. Depending on the split ratio (1:32, 1:64, or higher), a single OLT can serve thousands of end-users.
