GPON ONU Stick SFP Module | Class B+ | 2.5G/1.25G | Terminal Transceiver

Overview

The GPON ONU Stick SFP Transceiver (Class B+) is a revolutionary protocol-translating module designed to integrate GPON broadband access directly into standard networking equipment. By embedding the functionalities of a GPON ONU (Optical Network Unit) into a compact SFP form factor, this “Stick” eliminates the need for a separate bulky modem or ONU box.

Compliant with ITU-T G.984 standards, it plugs directly into the SFP port of switches, routers, or firewalls (such as MikroTik, Ubiquiti, or Cisco). It handles the full GPON OMCI stack and G.988 management protocols, presenting itself to the host device as a standard Ethernet interface while communicating with the ISP’s OLT on the fiber side.

Key Features

• Built-in MAC/SOC: Contains an internal Media Access Controller and GPON chipset to handle protocol conversion (GPON to Ethernet) independently of the host device.
• SFP “Stick” Design: Hot-pluggable SFP footprint allows for clean, wire-free integration into enterprise routers and switches.
• Class B+ Optics: Standard 20km reach with 1310nm Burst-Mode Transmitter and 1490nm Continuous-Mode Receiver.
• High Bandwidth: Supports asymmetric GPON rates of 2.488 Gbps downstream and 1.244 Gbps upstream.
• Management Interfaces: Configurable via OMCI from the OLT or locally via Web GUI/Telnet/SSH (depending on firmware version) for setting PLOAM passwords or LOID.
• Dying Gasp: Supports power-down notification to the OLT.

Applications

• FTTH for Enterprise: Connect office firewalls or routers directly to the ISP fiber feed without an ISP-supplied bridge modem.
• MDU/MTU Backhaul: Insert into a floor switch in an apartment complex to provide upstream GPON connectivity.
• Wireless Backhaul: Plug into outdoor wireless base stations (e.g., Ubiquiti EdgePoint) to feed data via GPON.
• Smart City Surveillance: Equip SFP-capable IP cameras or industrial switches with direct GPON access.

Specifications

Cross-Platform Compatibility

The GPON ONU Stick is unique as it requires compatibility on two fronts: the Host Device (where it is plugged in) and the Line Side (the ISP’s OLT equipment).

1. Host Device Compatibility

The module presents itself as a standard 1000BASE-X or 2500BASE-X Ethernet SFP. It is widely tested with:

• MikroTik: CCR Series, CRS Series, RB3011, RB4011, RB5009 (Requires fixing SFP speed to 1G or 2.5G manually).
• Ubiquiti: EdgeRouter (X SFP, 4, 6, 12), UniFi Dream Machine Pro, USW Series.
• Cisco/Juniper/Arista: Enterprise switches (may require `service unsupported-transceiver` commands).
• Media Converters: Standard SFP-to-RJ45 media converters.

2. OLT (Line Side) Compatibility

The internal GPON stack is compatible with major OLT vendors via OMCI:

• Huawei: MA5600T, MA5800 Series
• ZTE: C300, C320, C600
• Nokia/Alcatel-Lucent: 7360 ISAM (May require specific software version on stick)
• FiberHome: AN5516 Series

Technical Note on Configuration

Unlike standard transceivers, this “Stick” is an active network device. To register with an ISP, you often need to clone the SN (Serial Number), PLOAM Password, or LOID of the original ISP-provided ONU. This module typically provides a management IP (e.g., 192.168.1.1) accessible via the host device for configuration.

FAQ

1. Does this replace the modem provided by my ISP?

Yes, this SFP module functions as a bridge modem. It replaces the ONU/ONT box. However, you will still need a router (the host device) to handle PPPoE dialing, NAT, and Wi-Fi.

2. How do I configure the PLOAM password?

The module usually has a web interface or Telnet access. You must configure a static IP on your router’s SFP interface (e.g., 192.168.1.2) to access the module’s default IP (e.g., 192.168.1.1) and enter the credentials provided by your ISP.

3. Will it work with 2.5Gbps ports?

Yes. While the upstream is 1.25G, the downstream is 2.5G. If your host switch/router supports HSGMII (2.5G SFP) negotiation, you can achieve the full downstream throughput. On 1G SFP ports, the speed will be limited to 1Gbps.

4. Is the connector SC/APC or SC/UPC?

This specific product page lists the interface as SC/UPC (Blue). Please check your patch cable. If your wall outlet uses SC/APC (Green), you will need an APC-to-UPC patch cord to avoid signal loss.
