The Extralink OLT BDCOM P3310D EPON network switch, 4GE is a durable, high-performance rack-mounted Optical Line Terminal (OLT) designed for efficient Ethernet Passive Optical Network (EPON) solutions. This device is suitable for various applications, including broadband access services and FTTx deployments.

• Compliance: Fully compliant with IEEE 802.3ah standard and PRC YD/T 1475-2006 interface standard.
• PON Support: Four EPON PON ports with symmetrical transmission at 1.25 Gbps.
• Uplink Options: Features 2 static Gigabit Ethernet TX ports and 2 GE SFP ports.
• Management Interfaces: RJ45 console, mini-USB console, and out-of-band management port.
• System Performance: 20 Gbps bandwidth, 128 MB DRAM, and 32 MB Flash memory.
• Reliability: 100,000 hours MTBF with dual power supply in certain versions.

This terminal supports up to 1:64 ONUs per PON port, maximizing access and bandwidth utilization. Additionally, its compact 1U rack-mount design ensures minimal footprint, thereby reducing operational costs through lower power consumption. For enhanced performance and management, the device guarantees Quality of Service (QoS) and features such as Dynamic Bandwidth Allocation (DBA). The optical fiber protection ensures stability by automatically disconnecting connections during interruptions, supporting a reliable network environment.
