Providers can add more users to an existing fiber line without needing to overhaul the entire physical infrastructure.

A Passive Optical Network (PON) is a fiber-optic telecommunications technology that delivers high-speed internet by using a "point-to-multipoint" architecture. Unlike active networks, a PON uses unpowered optical splitters to share a single fiber line among multiple end-users. According to Cisco , the core of this system involves:

The deployment of parts like the is critical in "Fiber to the Home" (FTTH) rollouts. These components ensure that the signal remains strong and clear even after being split multiple times. For enthusiasts looking for specific hardware for network builds, technical guides on FS.com provide detailed tutorials on how OLTs and ONUs interact within these systems.

Components like the are typically found within the OLT or ONT modules. These parts are designed to handle the increasing bandwidth requirements of modern applications, such as 4K streaming, online gaming, and remote work.

Newer iterations of PON, such as XGS-PON, can offer symmetrical speeds of up to 10 Gbps.
