Frequently Asked Questions - MG-120 Planet
What is the Planet MG-120 used for?
The Planet MG-120 is a Gigabit media converter that connects twisted-pair copper cabling to fiber optic networks. It extends network distances up to 80 km using standard SFP modules.
How do I install the MG-120?
Simply connect the RJ45 port to a copper Ethernet device and insert an SFP module into the SFP slot. Connect the fiber cable to the SFP module and plug in the power adapter. The device is plug-and-play and requires no software setup.
Which SFP modules are compatible with the MG-120?
The MG-120 supports standard 1000Base-SX/LX SFP modules. Any SFP module that meets the IEEE 802.3z standard and has a gigabit speed will work, provided it matches the fiber type (multimode or single-mode) and wavelength.
Can I use a fiber optic cable directly without an SFP module?
No, the MG-120 only has an SFP slot for fiber connection. You must install a transceiver module in the slot and then connect the fiber cable to it.
How can I troubleshoot if the link is not established?
Check that the power LED is on. Verify that both the copper and fiber cable connections are secure. Ensure the SFP module and fiber cable are compatible with the same speed and wavelength. Try swapping the SFP module or using a known-good fiber cable to isolate the issue.
What do the LED indicators mean?
The Power LED lights when the device is powered. Link/Act shows a steady light when a link is established and blinks with activity. FDX indicates full duplex mode, and 1000M lights when the connection speed is 1 Gbps.
Does the MG-120 require configuration?
No, the MG-120 is a plug-and-play device. It automatically negotiates the duplex mode and speed on the copper port. There is no web interface or management configuration needed for basic operation.
Can I use it as a standalone converter?
Yes, the MG-120 is designed to work as a standalone media converter. You can place it on a desktop or mount it on a wall or DIN rail using optional accessories, and it will convert between copper and fiber seamlessly.
What is the maximum distance supported?
The maximum distance depends on the SFP module and fiber type. With a suitable single-mode SFP module and single-mode fiber, distances up to 80 km can be achieved. Multimode SFP modules typically support up to 550 m.
How do I clean and maintain the device?
Keep the device clean by wiping the exterior with a soft, dry cloth. Never use liquid cleaners or sprays. Regularly inspect the SFP slot and fiber connectors to ensure they are free of dust and debris. Avoid touching the fiber ends and use protective caps when not in use.
