Keep critical Ethernet links active with a TAA-compliant SFP designed for 1000BASE-MX multimode deployments. The AddOn MGB-SX2-AO fits standard SFP ports and uses an LC duplex connector to support 1 GbE connectivity over MMF, making it a straightforward choice for access switches, aggregation points, and fiber runs where predictable interoperability matters. This module is built for teams that need a reliable replacement or expansion optic without overpaying for unnecessary features. Its 850 nm multimode design aligns with common enterprise fiber plant requirements, while the compact SFP form factor supports hot-swap maintenance in live environments. For procurement teams, TAA compliance helps satisfy sourcing requirements without changing the network design. Use it where short-reach fiber links need stable throughput and clean deployment economics. Whether you are standardizing spares, replacing failed optics, or extending switch-to-switch connectivity across a campus, this transceiver keeps the focus on uptime, compatibility, and controlled cost.
