Understanding GPON Technology
GPON utilizes a point-to-multipoint architecture, where a single optical line terminal (OLT) at the central office serves multiple optical network units (ONUs) at subscriber premises. This shared infrastructure significantly reduces the cost of fiber deployment compared to point-to-point solutions. The system relies on wavelength division multiplexing (WDM), allowing for simultaneous upstream and downstream data transmission over a single fiber optic cable. This efficiency is a key factor in its widespread adoption.
