Frequently Asked Questions

When it comes to GPON network architecture types, there are several key questions that often arise. Below, we've provided answers to some of the most common queries to help you better understand this topic.

How does a GPON network architecture work?

A GPON (Gigabit Passive Optical Network) architecture uses fiber optic cables to deliver high-speed internet access and other telecommunications services to users. It consists of an Optical Line Terminal (OLT) located at the service provider's central office and Optical Network Units (ONUs) installed at the users' premises. The OLT acts as a gateway, connecting the GPON network to the wider internet, while the ONUs serve as endpoints for individual users.

Through the use of Time Division Multiplexing (TDM) and Wavelength Division Multiplexing (WDM), a GPON network can transmit both upstream and downstream data simultaneously, providing symmetrical speeds for both uploads and downloads. This architecture allows for efficient sharing of network resources, making it suitable for delivering high-bandwidth applications such as video streaming and cloud-based services.

What are the different types of GPON network architecture?

There are two common types of GPON network architecture: point-to-multipoint (P2MP) and active Ethernet (AE). In a P2MP architecture, the OLT is connected to multiple ONUs, allowing it to serve multiple users simultaneously. This architecture is cost-effective and widely used for residential and small business applications.

On the other hand, active Ethernet architecture uses dedicated point-to-point connections between the OLT and each ONU. This architecture provides each user with a dedicated connection, offering high bandwidth and low latency. Active Ethernet is typically used in larger corporate networks where high-performance and guaranteed bandwidth are crucial.
