Product Information

Full details

The Allied Telesis AT-MMC2000/SP-960 is an ideal solution for IT professionals and network administrators needing to extend copper-based Gigabit Ethernet networks over multi-mode fiber optic cabling. It delivers seamless 10/100/1000T to 100/1000X conversion while maintaining support for IEEE 802.1Q VLAN tags, making it highly compatible with modern high-performance infrastructure. The main caveat for users is that, as a dedicated SFP-based device, it requires a compatible SFP module to be purchased separately if one is not already integrated into the network topology.

FAQs

Does this device support single-mode fiber?

The AT-MMC2000/SP-960 is designed for multi-mode fiber structures. Compatibility with single-mode fiber depends on the specific SFP module installed.

Can I mount this in a rack?

Yes, this converter is compatible with the Allied Telesis MMCR18 rack-mount chassis for centralized management.

What is the maximum distance for the fiber connection?

The unit supports distances up to 500 meters depending on the fiber quality and the SFP module used.

Does it support Jumbo frames?

Yes, the device is built to support jumbo frames, making it suitable for high-speed enterprise network traffic.

What should I do if the link does not restore automatically?

Ensure that the link restoration features are not being blocked by port security settings on your managed switch.

Is the power supply included?

Yes, the product includes a multi-region power supply unit for operation.

Troubleshooting

No link light on the fiber port

Verify that the SFP module is seated correctly and check that the fiber cable is not bent beyond its minimum bend radius.

Network communication is intermittent

Perform a Link Test to isolate which side of the converter is experiencing the fault; inspect the copper patch cable for damage.

Device is powered but unresponsive

Check the input voltage from the power supply and ensure the LED indicators are displaying status signals; power cycle by unplugging and reconnecting.

Setup, Compatibility & Care

To set up the converter, connect your Cat5e or Cat6 copper cable to the RJ-45 port and your multi-mode fiber SFP module into the SFP slot. Ensure the device is connected to a stable 12V power source using the provided adapter. The device is compatible with the Allied Telesis MMCR18 rack-mount chassis if you are managing multiple units. For care, keep the unit in a well-ventilated area within the operating temperature range of 0 to 50°C. Periodically inspect the SFP module for dust and ensure the fiber optic ends remain clean to prevent signal attenuation.
