Convert copper access links to multimode fiber with a compact platform built for controlled network expansion. The Allied Telesis AT-MMC200/ST-960 translates 10/100TX Ethernet to 100FX over ST multimode fiber, making it a practical choice when you need to extend reach, reduce electrical noise exposure, or connect older equipment to a fiber backbone. This model is especially useful in environments where legacy endpoints still matter. Instead of replacing functioning copper devices, you can place a media converter at the edge and carry traffic over fiber to the next aggregation point. That keeps migration costs focused on the links that need change, not the entire access layer. The ST multimode interface is a straightforward fit for short- to medium-distance fiber runs in closets, campus buildings, and industrial spaces. TAA alignment supports federal sourcing requirements, while the multi-region designation helps standardize deployment across distributed sites. For teams balancing uptime, compatibility, and procurement discipline, this is the kind of converter that earns its place in the rack by solving a specific problem cleanly.
