Secureye S-OLT-GPON-4OLT-L3D 4 Port Layer 3 GPON OLT with Dual Power Supply

The Secureye S-OLT-GPON-4OLT-L3D is a 4-port Layer 3 GPON Optical Line Terminal designed for FTTH deployments, ISP broadband services and fiber access networks. It supports up to 512 ONUs and offers a maximum optical split ratio of 1:128, making it suitable for scalable multi-user connectivity. The device includes four Gigabit RJ45 uplink ports and two SFP/SFP+ uplink interfaces for flexible network integration. Layer 2 switching, VLAN management, QoS, multicast handling and Layer 3 routing features help administrators manage network traffic efficiently. With EMS, Web, Telnet, CLI and SSH management options, the OLT supports centralized monitoring and configuration. Its compact 1U rackmount chassis and dual power supply backup support make it a practical choice for service providers and enterprise fiber networks.
