What Are the Layers of the FTTH Network?

This technology ensures superior performance compared to traditional copper-based networks. The FTTH network design is composed of several layers that work together to provide seamless data transmission. Let’s explore these layers and their roles in delivering high-speed internet to users.

Core Network Layer: The core network layer is the backbone of the FTTH infrastructure. It consists of high-capacity fiber-optic cables that transmit data over long distances. These cables connect major data centers and internet exchanges, ensuring reliable data flow between regions and countries. The core layer provides the foundation for the entire FTTH system by supporting high bandwidth and low latency.

Metro/Distribution Layer: This layer connects the core network to specific metropolitan areas or regions. It acts as a bridge between the core and access layers. The metro layer includes distribution hubs and aggregation switches that manage and route data traffic to ensure optimal performance. This layer helps maintain a balance between network capacity and user demand.

Access Network Layer: The FTTH network connects directly to individual homes and businesses in the access layer. This layer includes Optical Line Terminals (OLTs) at the service provider’s end and Optical Network Terminals (ONTs) at the user’s premises. The connection is typically established using Passive Optical Networks (PONs), which reduce the need for active components and maintenance.

Customer Premises Equipment (CPE) Layer: This layer comprises devices installed at the customer’s location, such as routers, modems, and ONTs. These devices convert optical signals into electrical signals that computers, smartphones, and other connected devices can use. The CPE layer ensures that users can access high-speed internet seamlessly.
