Allied Telesis AT-MMC2000/SP-960 network media converter 1000 Mbit/s 850 nm Multi-mode Silver

The Allied Telesis AT-MMC2000/SP-960 is a compact Gigabit Ethernet to SFP mini media and rate converter that converts 10/100/1000T copper to 100/1000x fiber via an SFP port. Designed for multi-mode fiber links, it supports up to 500 m distance (850 nm wavelength) and fits into the MMC rack-mount chassis (MMCR18). The unit is CE and UL60950-1 certified and features a silver enclosure with low power consumption (approximately 1.7 W).

Advantages

The AT-MMC2000/SP-960 offers space-saving and energy-efficient operation, providing over 50% power savings compared with larger converters. It supports IEEE 802.1Q long packets for VLAN compatibility, includes Smart MissingLink (SML) monitoring and Smart Link Restoration for automatic recovery after link interruptions, and provides a link test function to quickly identify port or cable faults. Its SFP fiber interface ensures flexible use with compatible multi-mode transceivers.

Suitable for

• Extending copper Gigabit Ethernet networks over multi-mode fiber up to 500 m
• Integration into dense rack deployments using the MMC series chassis (MMCR18)
• Networks requiring VLAN support (IEEE 802.1Q) and reliable link monitoring

How to use

Install the AT-MMC2000/SP-960 as a standalone unit or mount it in the MMCR18 chassis if additional converters are used. Connect the RJ-45 copper link to the 10/100/1000T port and insert a compatible SFP transceiver into the SFP slot, then attach the multi-mode fiber cable. Power the unit using the supplied external power adapter. Use the built-in link test to verify connectivity and monitor link status using the Smart MissingLink feature to locate failures quickly.

Recommendations

Use SFP transceivers and fiber cabling that match multi-mode specifications (850 nm) for distances up to 500 m. Ensure connected switches support IEEE 802.1Q if VLAN-tagged long packets are used. For dense deployments, mount converters in the MMCR18 chassis and allow adequate ventilation around the unit to maintain low-power operation.
