Allied Telesis AT-2911SX/ST-901 – TAA PCIe Gigabit Fiber NIC ST Connector

Overview

The Allied Telesis AT-2911SX/ST-901 is a TAA-compliant PCI Express gigabit Ethernet adapter card designed for servers and workstations requiring fiber LAN connectivity via an ST connector. The adapter operates on the 1000BASE-SX standard over multimode fiber with a maximum reach of 550 meters. It supports both 32-bit and 64-bit PCIe slots, and the package includes both low-profile and full-height brackets to accommodate different chassis form factors. The -901 suffix designates TAA compliance for U.S. federal procurement requirements.

Description

The AT-2911SX/ST-901 provides a direct path for servers and workstations to connect to multimode fiber Gigabit Ethernet infrastructure using a PCIe host interface. The ST connector format makes this adapter compatible with installed fiber plant in data centers, campus buildings, and government facilities that standardized on ST terminations.

Operating at 1000BASE-SX, the card uses an 850nm laser source and supports link distances up to 550 meters on 50/125µm multimode fiber (OM2 or better). This coverage is sufficient for most intra-building or inter-floor fiber runs in enterprise and government environments.

The card installs in any standard PCIe x1 or wider slot — the x1 electrical interface fits in x1, x4, x8, and x16 mechanical slots. Both a standard-height and a low-profile bracket are included in the package, so the adapter can be installed in rack-mounted 1U/2U servers and in smaller tower or low-profile workstation chassis without requiring an additional accessory order.

TAA compliance under the -901 designation confirms the card meets Trade Agreements Act requirements, making it eligible for U.S. federal, state, and local government procurement under GSA schedules and similar programs.

Key Features

• TAA Compliant (-901): Meets Trade Agreements Act requirements for U.S. federal, state, and local government procurement without requiring a waiver.
• 1000BASE-SX over Multimode Fiber: Delivers full gigabit throughput over 50/125µm or 62.5/125µm multimode fiber at distances up to 550 meters on OM2+.
• ST Connector Interface: Compatible with existing ST-terminated fiber plant commonly found in legacy enterprise and government facilities.
• 32/64-Bit PCIe Interface: Installs in any PCIe x1 or wider slot, compatible with both 32-bit and 64-bit host systems running current server operating systems.
• Dual Bracket Included: Ships with both full-height and low-profile brackets, eliminating the need for a separate accessory purchase when installing in compact chassis.
• Broad OS Support: Compatible with Windows Server, Linux, and other major server operating systems supported by Allied Telesis driver packages.

Typical Applications

• Federal Government Data Centers: Connecting TAA-required servers to existing ST-terminated fiber infrastructure under GSA or DoD procurement contracts.
• Campus Building Uplinks: Providing fiber Ethernet connectivity for servers in buildings where the horizontal cabling plant uses ST-terminated multimode fiber.
• NAS and Storage Server Connectivity: Adding a dedicated fiber Ethernet port to a network-attached storage server to isolate storage traffic from general LAN traffic.
• Workstation-to-Switch Fiber Links: Connecting high-performance workstations in video production or engineering environments directly to a fiber-connected switch.
• Server NIC Replacement: Replacing failed or end-of-life fiber NICs in existing server infrastructure without requiring a fiber plant recabling to a different connector format.
