ZyXEL PX3321-T1 GPON ONT EU Generic F - GPON Optical Network Terminal

The ZyXEL PX3321-T1 is a high-performance GPON Optical Network Terminal (ONT) designed for fiber-to-the-home (FTTH) deployments. Compliant with ITU-T G.984 standards, it delivers reliable gigabit-speed connectivity for residential and small business users. The compact unit features a single GPON SC/APC port and one Gigabit Ethernet LAN port, supporting downstream data rates up to 2.488 Gbps and upstream up to 1.244 Gbps. With advanced security features like AES-128 encryption and FEC, and management via OMCI or TR-069, the PX3321-T1 ensures secure, efficient, and easy-to-manage network access.

Advantages
