Extend Ethernet farther without redesigning the network. The Allied Telesis AT-MMC2000/SP-960 converts 10/100/1000T copper to 100/1000X over SFP, giving you a practical way to connect legacy copper devices to fiber uplinks and remote segments. It is a strong fit for federal and multi-region environments where procurement requirements, interoperability, and deployment flexibility all matter. This media and rate converter helps preserve existing switching investments while opening the door to fiber runs where distance, EMI, or rack layout make copper less practical. Support for SFP-based optics lets teams match the transceiver to the link requirement instead of locking into a fixed optical path. That flexibility matters when you are standardizing across sites, managing spares, or building around approved components. For infrastructure teams, the value is in controlled migration. You can convert media at the edge, keep traffic flowing, and avoid unnecessary chassis upgrades. For procurement, TAA alignment and multi-region positioning make it easier to source a unit that fits regulated environments. This is the kind of converter selected when uptime, compatibility, and deployment discipline matter more than lowest-cost hardware.
