EPON ONU Stick SFP Module | PX20+ | Symmetric 1.25G | Terminal Transceiver

Overview

The EPON ONU Stick SFP Transceiver (PX20+) is a high-performance optical terminal designed to replace traditional desktop EPON modems. By integrating the ONU (Optical Network Unit) chipset and MAC address controller directly into an MSA-compliant SFP form factor, this module allows you to plug a fiber connection directly into your enterprise router, switch, or firewall.

Compliant with IEEE 802.3ah standards, this “Stick” creates a seamless bridge between the ISP’s passive optical network and your local Ethernet equipment. It delivers symmetric 1.25 Gbps bandwidth and supports standard OAM (Operations, Administration, and Maintenance) for remote management, making it an ideal solution for FTTx upgrades, reducing cabling clutter, and eliminating power bricks associated with standalone ONUs.

Key Features

• Integrated ONU Functionality: Contains a built-in EPON MAC and PHY, handling the complete IEEE 802.3ah protocol stack internally.
• Symmetric Gigabit Speed: Provides 1.25 Gbps Upstream and 1.25 Gbps Downstream throughput.
• PX20+ Optical Class: enhanced optical budget ensuring reliable connections up to 20km with a split ratio of 1:64.
• Plug-and-Play Design: Hot-pluggable SFP footprint compatible with standard SFP cages in routers and switches.
• Management Support: Supports CTC 2.1/3.0 extended OAM for compatibility with major OLT vendors, allowing remote configuration and status monitoring.
• Dying Gasp: Sends a final signal to the OLT upon power failure to aid in fault diagnosis.

Applications

• Enterprise FTTH: Direct fiber termination into gateway routers (e.g., MikroTik CCR, Ubiquiti EdgeRouter) for businesses.
• Video Surveillance: Connect IP cameras directly to the EPON network without intermediate media converters.
• Wireless Backhaul: Provide fiber backhaul to outdoor Wi-Fi access points or LTE small cells equipped with SFP ports.
• MDUs: Deploy in floor switches for apartment complexes to distribute Gigabit Internet.

Specifications

Cross-Platform Compatibility

The EPON ONU Stick serves as a bridge between your local network equipment and the ISP’s infrastructure. It requires compatibility on both sides:

1. Host Device Compatibility (Router/Switch)

The module appears as a standard Gigabit Ethernet SFP to the host. It is verified to work with:

• MikroTik: RB4011, RB5009, CCR1009/1036, and CRS switches (ensure port is set to 1G/auto-negotiation off if needed).
• Ubiquiti: EdgeRouter X SFP, EdgeRouter 4, UniFi Switch (USW) series, UDM Pro.
• Cisco/Juniper: Enterprise routers supporting 3rd party transceivers.
• Generic: TP-Link, Netgear, and D-Link switches with SFP slots.

2. OLT (Line Side) Compatibility

The internal chipset supports standard IEEE 802.3ah and extended CTC OAM, ensuring interoperability with major EPON OLT brands:

• Huawei: MA5600T, MA5680T, MA5800 Series.
• ZTE: C220, C300, C320.
• FiberHome: AN5516 Series.
• BDCOM: P3310, P3600 Series (Popular in EPON deployments).
• VSOL/C-Data: Generic EPON OLTs.

Technical Configuration Guide

To successfully register this ONU Stick with your ISP, you may need to replicate the credentials of your original modem. The module typically offers a web interface (accessible via a default IP like 192.168.1.1 when your host device is configured on the same subnet) to configure:

• MAC Address Cloning: Change the SFP’s MAC to match your ISP-registered device.
• LOID/Password: Input the Logical ONU ID if your ISP uses LOID authentication.
• VLANs: Configure VLAN tagging if required, though this is often handled by the host router (WAN tagging).

FAQ

1. What is the difference between this EPON Stick and a GPON Stick?

EPON and GPON are different protocols. This module (EPON) uses symmetric 1.25Gbps speeds and IEEE 802.3ah standards. A GPON Stick uses asymmetric 2.5G/1.25G speeds and ITU-T G.984 standards. They are not interchangeable; you must match the technology your ISP uses.

2. Does this support “Triple Play” (Internet, IPTV, VoIP)?

Yes, the hardware supports high-speed data transmission required for Triple Play. However, specific VLAN configurations for IPTV and VoIP must be handled by your host router (e.g., configuring VLAN sub-interfaces on MikroTik/Ubiquiti).

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

This module uses an SC/UPC (Blue) connector. If your wall fiber outlet is Green (SC/APC), you must use an APC-to-UPC patch cable to prevent high optical loss.

4. Can I use this in a 10G SFP+ port?

Yes, provided the SFP+ port supports dual-rate (1G/10G) operation. You may need to manually force the link speed to 1Gbps in your switch settings.
