What Is an XGS-PON Stick ONU SFP Transceiver?

An XGS-PON Stick ONU SFP Transceiver is a compact fiber access module designed to replace traditional ISP ONT devices in FTTH broadband networks.

It combines ONU functionality with an SFP transceiver form factor, allowing direct installation into compatible routers, switches, firewalls, and networking devices.

The module is widely used in:

• ISP bypass setups
• MikroTik routers
• OpenWRT systems
• Home lab networking
• FTTH broadband deployments
• Fiber WAN applications

Why Use an XGS-PON Stick ONU?

Traditional ISP ONT devices often require separate power supplies, additional cabling, and limited network flexibility.

An XGS-PON Stick ONU SFP module simplifies deployment by integrating fiber access directly into the networking device.

Benefits include:

• Cleaner network setup
• Lower power consumption
• Reduced hardware requirements
• Direct fiber WAN integration
• Better compatibility with advanced routing systems

Typical Applications

• ISP ONT replacement
• FTTH broadband access
• MikroTik fiber WAN deployment
• OpenWRT router integration
• Home lab fiber networking
• 10G fiber internet access
• Router SFP WAN conversion

Compatible Networking Platforms

This XGS-PON ONU Stick is commonly used with:

• MikroTik routers
• OpenWRT systems
• pfSense firewalls
• OPNsense platforms
• Linux-based routers
• Managed switches with SFP ports

Compatibility may vary depending on ISP authentication requirements and firmware support.

Typical Optical Power Range

In most XGS-PON deployments, ONU optical receive power typically operates within the following range:

Optical Power Level	Status
-8 dBm to -18 dBm	Excellent
-18 dBm to -23 dBm	Stable
-23 dBm to -27 dBm	Weak Signal
Below -27 dBm	Possible ONU Disconnect

Maintaining stable optical signal levels helps ensure reliable FTTH broadband performance.

Common ISP Bypass Scenarios

Many advanced users replace ISP ONT devices to gain:

• Full router control
• Better VLAN management
• Advanced firewall features
• Lower network latency
• Simplified fiber WAN deployment

An XGS-PON Stick ONU allows direct fiber termination inside the router without external ONT hardware.

Important Compatibility Notes

Before deployment, verify:

• ISP authentication method
• OMCI compatibility
• Serial number requirements
• VLAN configuration
• Router SFP compatibility
• Power consumption limitations

Some ISPs may require additional configuration for successful ONU registration.

Why XGS-PON Is Popular for Home Labs

XGS-PON supports multi-gigabit FTTH broadband speeds, making it attractive for:

• 10G home networking
• self-hosted servers
• NAS environments
• virtualization labs
• advanced routing setups

Many home lab users prefer XGS-PON ONU sticks for compact and flexible fiber integration.

General Description

The XGS-PON ONU stick transceiver is an Optical Network Terminal (ONT) with Small Form-factor Pluggable (SFP+) packaging. The XGS-PON ONU stick integrates a bi-directional (max 10Gbit/s) optical transceiver function and 2nd layer function. By being plugged into the customer premise equipment (CPE) with standard SFP port directly, the XGS-PON ONU stick provides multi-protocol link to the CPE without requiring separate power Supply.

The transmitter designed for single mode fiber and operates at wavelength of 1270nm. The transmitter uses a DFB laser diode and fully compliant with IEC-60825 and CDRH class 1 eye safety. It contains APC functions, a temperature compensation circuit to ensure compliance with ITU-T G.9807 requirements at operating temperature.

The receiver section uses a hermetic packaged APD-TIA (APD with trans-impedance amplifier) and a limiting amplifier. The APD converts optical power into electrical current and the current is transformed to voltage by the trans-impedance amplifier. The differential signals are produced by the limiting amplifier. The APD-TIA is AC coupled to the limiting amplifier through a low pass filter.

The XGS-PON ONU stick supports a sophisticated ONT management system, including alarms, provisioning, DHCP and IGMP functions for a stand-alone IPTV solution at the ONT. It can be managed from the OLT using G.988 OMCI.

Notes:

1. Default Factory Mode is Tx Fault. For Small Cell type of applications, during Activation/ provisioning, it will be

software configured to ToD.

2. This PIN is an open collector/drain output pin and shall be pulled up with 4.7K-10K ohms to a Host_Vcc on the

host board.

3. PIN7 can support Dying Gasp function. Dying Gasp function is managed by software. If software turn off the dying

gasp function,no influence to the module if logical “0” or “1”. If software turn on the function,no influence to the

module if logical “1”; if logical “0”, the module will report dying gasp to OLT and the module will repeating restart.

4. Default Factory Mode is Veer. For Small Cell type of applications, during Activation/ provisioning, it will be software

configured to 1PPS.
