Extralink OLT BDCOM P3310D EPON 4GE IEEE 802.3ah EX.16965

Extralink OLT BDCOM P3310D EPON 4GE IEEE 802.3ah EX.16965 is an optical line terminal designed for deployment in access networks and fiber-to-the-home/curb (FTTx) architectures. The P3310D model integrates four fixed PON ports and supports symmetric EPON transmission at 1.25 Gbps. It provides multiple Gigabit uplink options including SFP and electrical ports, a dedicated console port, an external 10/100 management port, 90–264V AC power input and a 19" rack-mount chassis. The platform supports up to 1:64 split ratios and can operate with mixed ONU types to deliver broadband, voice and IPTV services over a common fiber infrastructure.

Advantages

The OLT implements IEEE 802.3ah EPON standards, ensuring interoperability with compliant ONUs and predictable performance. Multiple uplink interfaces (optical SFP and electrical Gigabit ports) give flexibility for integration into existing networks. The device’s 1.25 Gbps symmetric PON links and 1:64 support enable efficient bandwidth allocation for residential and business customers while reducing transport and aggregation costs. Rack-mount form factor and broad AC input voltage make the unit suitable for typical central office and cabinet installations.

Suitable for

• FTTx deployments for residential broadband delivery
• Small to medium ISP access aggregation
• Triple-play services: Internet, voice (VoIP) and IPTV distribution
• Network edge upgrade where IEEE 802.3ah EPON compatibility is required

Key specifications

• PON technology: EPON compliant with IEEE 802.3ah
• PON ports: four fixed PON ports supporting 1.25 Gbps symmetric links
• Split ratio support: up to 1:64
• Uplink interfaces: two optical Gigabit SFP ports and two Gigabit combo/electrical ports
• Management and console: dedicated console port and external 10/100 management port
• Power: AC input 90–264 V
• Form factor: 19-inch rack-mount enclosure

How to use

Install the OLT in a standard 19" rack and connect AC power within the specified 90–264 V range. Connect upstream aggregation links using the optical SFP modules or the electrical Gigabit ports according to your network design. Terminate subscriber fiber to the PON ports using compatible ONU/ONT devices and configure PON profiles, bandwidth allocation and VLANs through the device management interface or via a central management system. Use the console port for initial setup and the 10/100 management port for out-of-band administration if required.

Usage recommendations

Ensure ONUs connected to the P3310D conform to EPON (IEEE 802.3ah) compatibility to maintain link stability. Plan split ratios and bandwidth profiles per service type to avoid oversubscription during peak hours. Place the unit in a ventilated rack space and use appropriate SFP modules rated for your link distances and fiber type.
