Extend a PCIe-based system onto multimode fiber without changing the network design. The StarTech PEX1000MMSC2 adds Gigabit Ethernet connectivity through an SC duplex fiber interface, making it a practical fit for server rooms, industrial closets, and rackmount systems that need a direct fiber uplink. With support for multimode fiber up to 550 m, it gives you the reach copper cannot provide while preserving a simple, point-to-point installation model. This adapter is built for environments where uptime, cable distance, and physical compatibility matter. The included standard-profile and low-profile brackets make it easier to match full-height desktops or half-height systems, reducing the need for separate accessories. TAA compliance also makes it suitable for procurement workflows that require sourcing alignment for public sector and regulated deployments. For teams replacing aging copper runs or adding a dedicated fiber path to a workstation or server, this card offers a clean way to connect existing PCIe hardware to a multimode SC network with minimal complexity.
