Maintain dependable Gigabit fiber connectivity where compliance and compatibility matter. The StarTech GLCSXMMDSTT is a TAA-compliant SFP transceiver designed for 1000Base-SX links over multimode fiber, making it a practical fit for enterprise networks that need predictable performance and straightforward sourcing. With 850 nm optics and an LC connector, this module supports short-reach fiber runs up to 500 m, or 1,640 ft, depending on the fiber plant and deployment conditions. It is Cisco GLC-SX-MMD compatible, which helps simplify replacement planning in mixed-vendor environments and reduces the friction of maintaining legacy access and aggregation infrastructure. This module is well suited for teams that need to preserve existing switch investments while meeting procurement requirements tied to TAA compliance. For organizations standardizing on multimode fiber, it offers a clean path to extend Gigabit Ethernet without overbuying optics or redesigning the network layer. When the requirement is reliable short-distance fiber transport with verified compatibility, this SFP keeps the decision simple.
