4.2. Rear Panel (Ports and Buttons)
- Reset Button: Used to restore factory default settings. Press and hold for several seconds while the device is powered on.
- On/Off Switch: Powers the device on or off.
- Power Input: Connects to the 12V DC power adapter.
- LAN Port (GE): Gigabit Ethernet port for connecting to a router, computer, or other network devices.
- PON Port (SC/APC or SC/UPC): Optical port for connecting to the fiber optic network from the OLT. This model supports either SC/APC or SC/UPC connector types.
5. Setup Instructions
- Power Connection: Connect the provided 12V DC power adapter to the 'Power' input port on the rear panel of the F601. Plug the adapter into a power outlet. Ensure the 'On/Off' switch is in the 'On' position. The 'Power' LED on the front panel should illuminate.
- Fiber Optic Connection: Carefully connect the fiber optic cable from your service provider to the 'PON' port on the rear panel. Ensure the connector type (SC/APC or SC/UPC) matches your cable. Handle fiber optic cables with care to avoid damage. After connection, the 'LOS' LED should turn off, and the 'PON' LED should start flashing, then turn solid 'On' once registered with the OLT.
- Ethernet Connection: Connect an Ethernet cable from the 'LAN' port on the F601 to your router, computer, or other network device. The 'LAN' LED on the front panel should illuminate, indicating a successful link.
- Verification: Once all connections are made and the LEDs indicate normal operation (Power On, PON On, LOS Off, LAN On/Flashing), your F601 is ready to provide network services.
6. Operating Instructions
The ZTE F601 GPON ONU operates as a bridge between your home network and the fiber optic network. Once properly set up and connected, it automatically establishes a connection with your Internet Service Provider's (ISP) OLT to provide internet and IPTV services.
- Internet Access: Devices connected to the LAN port (either directly or via a router) will receive internet access once the PON connection is established and authenticated by your ISP.
- IPTV Services: If your service plan includes IPTV, the F601 will facilitate the delivery of these services to compatible devices connected to your network.
- Management: The device can be managed locally via a web interface (if enabled by your ISP) or remotely by your ISP using OMCI.
7. Maintenance
- Keep Clean: Ensure the device and its ports are free from dust and debris. Use a soft, dry cloth for cleaning.
- Ventilation: Do not block the ventilation holes on the device to prevent overheating.
- Environment: Operate the device within the specified temperature and humidity ranges (0℃~40℃, 5%~95% non-condensing humidity). Avoid direct sunlight, excessive heat, and moisture.
- Cable Management: Ensure all cables are securely connected and not bent or kinked, especially the fiber optic cable.
- Software Updates: Firmware updates are typically managed by your ISP remotely. Do not attempt to manually update firmware unless instructed by your service provider.
8. Troubleshooting
Refer to the LED indicator status (Table 1) for initial troubleshooting. If issues persist, contact your Internet Service Provider.
- No Power:
- Check if the power adapter is securely connected to the device and the power outlet.
- Ensure the 'On/Off' switch is in the 'On' position.
- Verify the power outlet is functional.
- LOS LED is On:
- Indicates a loss of optical signal. Check the fiber optic cable connection to the 'PON' port.
- Ensure the fiber cable is not damaged, bent, or disconnected at the other end (e.g., wall outlet).
- Contact your ISP if the issue persists, as it may indicate a problem with the external fiber network.
- PON LED is Off or Flashing Continuously:
- If 'LOS' is off but 'PON' is off, the ONU is not receiving a signal or is not registered.
- If 'PON' is flashing continuously, the ONU is attempting to register. This might take a few minutes.
- If it remains off or flashing for an extended period, contact your ISP.
- LAN LED is Off:
- Check the Ethernet cable connection between the F601's 'LAN' port and your connected device (router/PC).
- Ensure the connected device is powered on and its Ethernet port is active.
- Try a different Ethernet cable.
- No Internet Access:
- Verify all LEDs are in their normal operating state (Power On, PON On, LOS Off, LAN On/Flashing).
- Restart the F601 by turning it off and on using the 'On/Off' switch.
- Restart your router and connected devices.
- If using a router, ensure it is configured correctly for your ISP's network.
- Contact your ISP if the problem persists.

10. User Tips
- Fiber Optic Care: Always handle the fiber optic cable with extreme care. Avoid bending it sharply or applying excessive force, as this can damage the delicate fiber inside and lead to signal loss.
- Placement: Place the ONU in an open area with good ventilation to ensure optimal performance and prevent overheating. Avoid placing it near heat sources or in enclosed spaces.
- Power Cycle: If you experience intermittent connectivity issues, a simple power cycle (turning the device off, waiting 10-15 seconds, then turning it back on) can often resolve minor glitches.
- ISP Contact: For any complex network issues, configuration changes, or service-related problems, always contact your Internet Service Provider first. They have the necessary tools and access to diagnose and resolve issues related to your fiber connection and ONU.
