Keep server and workstation connections on fiber with a PCI Express Gigabit adapter designed for dependable network access. The Allied Telesis AT-2911SX/LC-901 pairs a PCI Express host interface with an LC connector to support 1,000 Mbps data transfer over fiber infrastructure. This adapter fits environments where copper is not the right answer: uplinks that need cleaner signal paths, longer reach, or tighter alignment with existing fiber plant. Its single-port design keeps the installation focused and straightforward, while the PCIe form factor supports integration into compatible systems without unnecessary complexity. For infrastructure teams, the value is in predictable connectivity. This is the kind of adapter chosen when the network path matters more than commodity pricing—when uptime, link stability, and compatibility with fiber-based switching are part of the requirement, not an afterthought.
