Keep multimode uplinks moving with a replacement transceiver that fits the operational reality of enterprise networks. This AddOn Networks SFP is compatible with D-Link DEM-312GT2 and supports 1000BASE-MX Gigabit Ethernet over multimode fiber. It is designed for teams that need a dependable optics replacement without reworking the switch, cabling, or support model. The TAA-compliant designation matters in environments where procurement rules are as important as technical fit. For public sector, education, healthcare, and regulated enterprise deployments, it helps simplify sourcing while preserving the installed fiber plant. The SFP form factor also makes it easy to stock as a spare for access switches, aggregation points, and distribution layers that still depend on multimode connectivity. When uptime depends on matching the right optic to the right port, this module offers a practical path forward. It supports continuity, reduces replacement friction, and keeps legacy Gigabit links serviceable at a lower operational cost than a broader hardware refresh.
