4. Physical Description
4.1 Front Panel
Figure 4.1: Front panel view of the GT-802S with ports and LED indicators.
The front panel of the GT-802S features the following components:
- 10/100/1000T Port: An RJ-45 connector for connecting to an Ethernet network device (e.g., switch, router, computer) using a standard Ethernet cable.
- Fiber Port (SC): An SC-type connector for single-mode fiber optic cable connection. This port consists of two parts: TX (transmit) and RX (receive).
- LED Indicators: Several LEDs provide status information:
- PWR: Power indicator. Lit when the device is powered on.
- 1000: Indicates a 1000Mbps (Gigabit) Ethernet connection on the RJ-45 port.
- LNK/ACT (TP): Link/Activity indicator for the RJ-45 (Twisted Pair) port. Lit when a link is established, blinks when data is being transmitted or received.
- LNK/ACT (Fiber): Link/Activity indicator for the Fiber port. Lit when a fiber link is established, blinks when data is being transmitted or received.
- LFP (Link Fault Pass-through): Indicates the status of the Link Fault Pass-through function.
4.2 Rear Panel

The device measures approximately 2.72 x 3.82 x 1.02 inches (6.9 x 9.7 x 2.6 cm).
5. Setup
Follow these steps to set up your GT-802S Media Converter:
- Power Connection: Connect the provided 5V DC power adapter to the power input port on the rear panel of the GT-802S. Plug the adapter into a standard electrical outlet. The PWR LED on the front panel should illuminate.
- Ethernet Connection: Connect one end of an Ethernet cable (Cat5e or higher) to the 10/100/1000T RJ-45 port on the GT-802S. Connect the other end of the Ethernet cable to your network device (e.g., switch, router, PC). The LNK/ACT (TP) LED should light up, and the 1000 LED should light up if a Gigabit connection is established.
- Fiber Optic Connection: Connect a single-mode fiber optic cable with SC connectors to the Fiber TX and RX ports on the GT-802S. Ensure the fiber cable is connected to a compatible fiber optic device at the other end. The LNK/ACT (Fiber) LED should light up when a stable fiber link is established.
Note: Ensure all cables are securely connected. For optimal performance, use high-quality cables.
6. Operating
Once properly set up, the GT-802S operates automatically. The LED indicators provide real-time status information:
- PWR (Green): Indicates the device is receiving power.
- 1000 (Green): Indicates the RJ-45 port is operating at 1000Mbps. If off, it's operating at 10/100Mbps.
- LNK/ACT (TP) (Green): Solid light indicates a valid Ethernet link. Blinking indicates data activity.
- LNK/ACT (Fiber) (Green): Solid light indicates a valid fiber link. Blinking indicates data activity.
- LFP (Green): Indicates the status of the Link Fault Pass-through function. Consult the full product manual for detailed LFP functionality.
7. Maintenance
To ensure the longevity and proper functioning of your GT-802S Media Converter, observe the following maintenance guidelines:
- Keep the device in a cool, dry environment, away from direct sunlight and heat sources.
- Ensure adequate ventilation around the unit.
- Clean the exterior with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Regularly inspect fiber optic connectors for dust or damage. Clean fiber connectors using appropriate fiber cleaning tools if necessary.
- Avoid placing heavy objects on top of the device.
8. Troubleshooting
If you encounter issues with your GT-802S, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power (PWR LED off) | Power adapter not connected or faulty; power outlet not working. | Ensure power adapter is securely connected to the device and a working power outlet. Test the outlet with another device. Replace power adapter if faulty. |
| No Ethernet Link (LNK/ACT TP LED off) | Ethernet cable faulty or disconnected; connected device is off or faulty; incorrect cable type. | Check Ethernet cable connections. Try a different cable. Ensure the connected network device is powered on and functioning correctly. |
| No Fiber Link (LNK/ACT Fiber LED off) | Fiber cable faulty or disconnected; fiber connectors dirty; connected fiber device is off or faulty; incorrect fiber type. | Check fiber cable connections. Ensure fiber connectors are clean. Verify the connected fiber device is operational and compatible. Ensure single-mode fiber is used. |
| Slow Ethernet Speed (1000 LED off) | Connected Ethernet device does not support Gigabit speed; cable quality. | Ensure the connected device's port supports 1000Mbps. Use a high-quality Cat5e or Cat6 Ethernet cable. |
