Allied Telesis AT-2911SX/SC-901 – TAA PCIe Gigabit Fiber NIC SC 1G

Product Overview

The Allied Telesis AT-2911SX/SC-901 is a TAA-compliant Allied Telesis PCIe fiber NIC SC 1 gigabit adapter designed for servers, workstations, and enterprise PCs requiring direct gigabit fiber connectivity. Using a PCI Express x1 host interface, this TAA federal 1000Base-SX fiber network card delivers up to 1000 Mbps over multimode fiber via its SC duplex connector. It is RoHS certified and federally compliant, qualifying for government procurement. The card fits both full-height and low-profile PCIe slots, making it compatible with rack-mount servers and compact form-factor systems alike.

Product Description

The AT-2911SX/SC-901 is a PCIe x1 gigabit Ethernet adapter card built on 1000Base-SX multimode fiber technology with a duplex SC connector. It delivers 250 MB/s bandwidth suitable for high-throughput server and workstation connectivity to fiber-based switched networks. The card is designed for 32/64-bit PCI Express x1 slots and is compatible with both full-height and low-profile chassis brackets, which are both included in the package. As a federal-compliant PCIe gigabit fiber NIC SC, it meets the Trade Agreements Act (TAA) requirements for use in U.S. federal and government deployments under GSA Schedule and similar procurement frameworks. The 1000Base-SX standard enables multimode fiber operation, connecting over 50/125 µm or 62.5/125 µm OM1/OM2/OM3 fiber at distances appropriate for intra-building and campus environments. Jumbo frame support up to 9000 bytes reduces CPU overhead for large data transfers in storage and virtualization environments. The card is manufactured in Singapore and holds RoHS certification. It is suitable for upgrading legacy copper NIC infrastructure in servers being connected to fiber-backbone switched networks, or for adding fiber connectivity to systems where copper ports are unavailable or insufficient. Compatible operating systems include Windows Server, Linux, and other major platforms supported by the underlying Broadcom or Intel chipset drivers.

Frequently Asked Questions

Q: Is the AT-2911SX/SC-901 TAA compliant for federal procurement?

Yes. This adapter is fully TAA compliant, qualifying it for U.S. federal government purchasing under GSA Schedule contracts and other government acquisition vehicles.

Q: What operating systems are supported?

The AT-2911SX/SC-901 supports major operating systems including Windows Server (2012/2016/2019/2022), Windows 10/11, and major Linux distributions. Refer to the Allied Telesis product page or driver documentation for the complete OS compatibility matrix.

Q: What fiber type and distance does this NIC support?

The card uses 1000Base-SX over multimode fiber (MMF) with duplex SC connectors. Supported fiber types include 50/125 µm and 62.5/125 µm. Distances depend on fiber grade: up to 550 m on 50/125 OM2, and up to 275 m on 62.5/125 fiber.

Q: Does the card fit in a low-profile server chassis?

Yes. Both full-height and low-profile PCIe brackets are included, allowing installation in 1U rack servers and compact form-factor systems with low-profile PCIe slots.

Q: What PCIe slot does it require?

The AT-2911SX/SC-901 uses a PCIe x1 interface. It can be installed in any PCIe slot (x1, x4, x8, or x16) on a 32-bit or 64-bit system.

Q: Does this NIC support jumbo frames?

Yes. Jumbo frames up to 9000 bytes are supported, which reduces CPU overhead for large data transfer workloads including backup, storage, and virtualization traffic.

Q: What is the difference between the SC and LC versions of the AT-2911SX?

The AT-2911SX/SC-901 uses an SC duplex fiber connector, while the AT-2911SX/LC-901 uses an LC duplex connector. Both are 1000Base-SX multimode fiber cards with identical PCIe x1 interfaces. Choose based on your existing fiber infrastructure and patch panel connector types.
