Extralink Predator 1U 8-Port EPON OLT

Description

What It Is and Who It’s For

The Predator is an EPON OLT — the headend device that drives a passive optical fibre network and manages subscriber ONUs. It is one of the latest OLT devices operating in EPON technology for optical fibre access networks, characterised by small dimensions, convenient and easy implementation, flexible functions and compatibility with most client units, sitting in a 1U 19″ rack chassis. It’s the EPON counterpart to the TP-Link DeltaStream GPON OLTs, and is well-suited to operators who have deployed — or plan to deploy — EPON infrastructure, including the Extralink Jowisz (EX-ONU-J) ONU listed elsewhere in this store.

Eight PON Ports, 512 ONUs

The Predator provides 8 EPON PON ports, supporting up to 512 ONUs at a 1:64 split ratio — 64 ONUs per PON port. Each PON port operates on the IEEE 802.3ah EPON standard with symmetric 1.25 Gbps upstream and downstream. Dynamic Bandwidth Allocation (DBA) is supported, allowing the OLT to efficiently distribute available upstream bandwidth across active ONUs in real time.

⚠️ EPON SFP modules sold separately. The 8 PON ports are SFP slots. EPON OLT SFP modules (1000BASE-PX20+) must be sourced separately.

Uplinks — 8 GE Copper + 8 SFP Combo

Uplink interfaces comprise 8 Gigabit Ethernet copper ports and 8 SFP ports operating in combo mode — each copper port is paired with an SFP slot and they share the same logical interface, so you use one or the other per combo pair. This gives substantial uplink flexibility: you can run copper Ethernet to an aggregation switch in the same rack, or fibre SFP for longer-reach or higher-density uplinks.

Broad ONU Compatibility

Unlike the Ubiquiti UISP fibre CPE range which is locked to Ubiquiti OLTs, the Predator follows the IEEE 802.3ah standard with standard OAM and CTC extensions, giving it compatibility with most client units. This means it works with the Extralink Jowisz (EX-ONU-J), as well as a broad range of third-party EPON ONUs from other vendors — an important consideration for operators migrating from an existing EPON network or supporting mixed CPE fleets.

Redundant Power and Reliability

Reliability is ensured by a double redundant power supply, providing failover between the two PSUs without service interruption — the same carrier-class feature present in the larger DeltaStream -04 and -08 OLTs.

Management

Management options include Telnet, CLI, and EMS (Element Management System) based on the standard SNMP protocol. The EMS platform provides ONU auto-detection and registration, MAC address assignment, loopback testing and filtering, bandwidth control, and multicast stream control — manageable across the full connected ONU fleet from a single interface. The device also includes a dedicated 1 GE management port and 1 Console port for out-of-band access.

Supported Services

The OLT supports Triple-Play, CPN, IP Camera, Enterprise LAN, and IoT applications. Layer 2 aggregation, 8K MAC address table, 4096 VLANs, 256 multicast groups, and ONU auto-detection and registration are all included.
