GPON ONU Stick SFP Module | Class B+ | SC/APC Connector | 2.5G/1.25G FTTx Terminal

Overview

Upgrade your network architecture with the GPON ONU Stick SFP Module, a revolutionary “system-on-a-chip” transceiver that integrates the functionality of a complete GPON Optical Network Unit (ONU) into a standard SFP form factor. Designed for Fiber-to-the-Home (FTTH) and business-grade P2MP applications, this module allows you to plug the fiber connection directly into your router, switch, or firewall, effectively eliminating the need for a separate, bulky ISP modem or media converter.

Compliant with ITU-T G.984 standards, this Class B+ module supports asymmetric data rates of 2.488 Gbps downstream and 1.244 Gbps upstream. It utilizes a robust SC/APC (Angled Physical Contact) receptacle to minimize back-reflection, ensuring superior signal integrity over distances up to 20km. Whether you are a telecom operator simplifying CPE deployment or a network enthusiast seeking a cleaner setup, this GPON Stick delivers enterprise-grade performance and reliability.

Key Features

• Integrated ONU Functionality: Complete GPON OMCI stack embedded within an MSA-compliant SFP package.
• High-Speed Performance: Supports 2.488Gbps (Down) and 1.244Gbps (Up) data links.
• Class B+ Optical Budget: High transmit power and sensitivity for reliable 20km reach.
• Connector Type: SC/APC (Green) interface for optimal return loss performance.
• Standard Compliance: Fully compatible with ITU-T G.984.x and SFP MSA.
• Advanced Management: Supports OMCI, Telnet, and Web GUI management (depending on firmware version) for configuration.
• Digital Diagnostics: Built-in DDM/DOM for real-time monitoring of voltage, temperature, and optical levels.

Applications

The primary application for the GPON ONU Stick is in FTTx networks where streamlining hardware is a priority. It is widely used to replace standalone ONT/ONU boxes provided by ISPs. By inserting this module directly into an SFP WAN port on a gateway or router (such as those from Ubiquiti or MikroTik), users can terminate the fiber service directly at their routing equipment.

Furthermore, this solution is ideal for wireless backhaul, surveillance networks, and multiple-dwelling units (MDUs) where space is limited. It allows for a “fiber-to-the-desk” architecture without the clutter of extra power adapters and plastic enclosures, simplifying power management and reducing potential points of failure.

Specifications

Cross-Platform Compatibility

The GPON SFP Stick is designed to be highly versatile. On the host side (where the SFP plugs in), it is compatible with a wide range of networking equipment that supports standard SFP modules. On the network side (the ISP side), it interacts with major OLT platforms. The table below outlines verified compatibility contexts.

Note: Successful authentication with the ISP’s OLT often requires configuring the PLOAM password and Serial Number (SN) within the SFP stick’s internal settings to match your provider’s credentials.

Advantages

Consequently, switching to an SFP ONU Stick offers significant advantages over traditional CPE setups. The most immediate benefit is the reduction of cabling clutter; there is no need for an AC power brick or an Ethernet patch cable between a modem and a router. This results in a cleaner, more professional installation.

Additionally, the device offers superior heat dissipation compared to plastic-cased ONUs due to its direct contact with the host switch’s metal cage. For network administrators, the ability to view optical statistics (DDM) directly from the router’s interface provides invaluable troubleshooting data that is often hidden in consumer-grade ISP modems.

FAQ (Technical & Product Questions)

1. Can I use this SFP stick to replace my ISP’s modem?

In many cases, yes. However, you must be able to configure the SFP stick with the specific authentication credentials (LOID, PLOAM password, or Serial Number) required by your ISP. Some ISPs lock their networks to specific hardware.

2. What is the difference between SC/UPC and SC/APC?

This module uses SC/APC (Green). APC connectors have an 8-degree angle polish to reduce back-reflection. You cannot use a Blue (UPC) connector with this module, as it will damage the port and cause high signal loss.

3. Does this module support 2.5Gbps speeds?

Yes, the GPON standard defines a downstream speed of approximately 2.5 Gbps. However, the actual throughput you receive depends on the host port’s interface (usually 1G or SGMII) and your subscribed internet plan.

4. Does it get hot during operation?

GPON Sticks consume more power than standard transceivers because they contain a full processor SOC. It is normal for them to run warm. Ensure your host equipment has adequate ventilation.

5. Is this a “MAC” or “Bridge” SFP?

This is a complete ONU on a stick. It typically functions as a bridge, stripping the GPON headers and passing Ethernet frames to your router. It handles the MAC layer of the GPON protocol internally.

6. How do I configure the PLOAM password?

Configuration methods vary by firmware version but are typically done via SSH/Telnet into the SFP’s IP address or via a web interface accessible when the SFP is plugged into a managed switch.
