1. Introduction
The LanYuXuan Mini GPON OLT (Optical Line Terminal) is a compact, all-metal fiber optic device designed for modern 4G and 5G network infrastructures. It integrates PON MAC functionality within an SFP+ package, offering a flexible and cost-effective solution for upgrading traditional data communication networks to all-optical networks. This manual provides essential information for the safe and efficient operation of your Mini GPON OLT.
2. Safety Information
Please read and understand all safety instructions before operating the device. Failure to follow these instructions may result in injury or damage to the device.
- Electrical Safety: Use only the specified 5V DC power adapter (5V-2A). Ensure proper grounding if applicable.
- Optical Safety: Never look directly into optical fiber ports or the end of fiber optic cables when the device is powered on. Invisible laser radiation can cause eye damage.
- Environmental Conditions: Operate the device within the specified temperature range (-40°C to 85°C) and humidity range (5% to 95% non-condensing).
- Handling: Handle the device with care. Avoid dropping or subjecting it to strong impacts.
- Ventilation: Ensure adequate ventilation around the device. Do not block the heat dissipation holes.

6. Operating Instructions
The Mini GPON OLT operates primarily in a plug-and-play manner, providing a 1000M network connection and supporting up to 32 ONU terminals.
6.1. Basic Operation
- Once powered on and connected, the OLT will automatically establish communication with connected ONUs (Optical Network Units).
- The device supports transparent transmission of SVLAN and CVLAN data in pure bridge mode.
- It is compatible with most HGU type ONUs and third-party switches, routers, and firewalls with optical ports.
6.2. Management Software
The Mini GPON OLT comes with self-developed PC-based management software for easy monitoring and configuration.
Figure 6.1: Software Interfaces Display.
Key features of the management software include:
- Support for fault display.
- Support for status display.
- Support for third-party API sharing for custom development.
- Windows Multi-Version Support.
Refer to the software's dedicated user guide for detailed instructions on its use.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid or aerosol cleaners.
- Optical Ports: Keep optical ports covered when not in use to prevent dust and contamination. Use appropriate fiber optic cleaning tools if necessary.
- Ventilation: Regularly check that the heat dissipation holes on the side panels are clear of obstructions.
- Firmware Updates: Check the manufacturer's website periodically for firmware updates to ensure optimal performance and security.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power (PWR LED off) | Power adapter not connected or faulty; power outlet issue. | Ensure power adapter is securely connected to the OLT and a working power outlet. Test with another adapter if available. |
| No fiber link (FX LED off/red) | Fiber cable disconnected, damaged, or dirty; SFP+ module not properly seated or faulty. | Check fiber cable connection. Inspect cable for damage. Clean fiber connectors if necessary. Re-seat the SFP+ module. |
| No network activity on RJ45 ports | Ethernet cable disconnected or faulty; connected device issue. | Verify Ethernet cable connections. Test with a different cable or device. Ensure the connected device is powered on and configured correctly. |
| ONUs not registering | Incorrect ONU configuration; OLT software issue; fiber link problem. | Ensure ONUs are compatible and correctly configured. Check OLT management software for status. Verify fiber link integrity. |
