Allied Telesis AT-2711FX/ST-901 Fast Ethernet ST Fiber PCIe x1 Network Adapter
Overview
The Allied Telesis AT-2711FX/ST-901 is a single-port 100BASE-FX Fast Ethernet network adapter in a PCIe x1 plug-in card form factor, connecting via ST fiber connector. It is designed for servers, workstations, or embedded systems that require a dedicated fiber Ethernet uplink without committing a higher-bandwidth PCIe slot — a practical fit when you need to integrate a host machine directly onto a 100Mbps fiber segment in a surveillance backhaul, industrial control, or legacy fiber LAN environment.
Compatibility
This adapter is compatible with systems equipped with a PCIe x1 (or open-ended PCIe x4/x8/x16) slot running a supported operating system for Allied Telesis AT-2711FX series drivers. The ST fiber interface connects to 100BASE-FX infrastructure — multimode fiber patch cables terminated with ST connectors. Verify your fiber plant is multimode (typically 62.5/125µm or 50/125µm OM1–OM3) before deploying; this adapter does not support single-mode fiber or 1000BASE-X operation. Confirm driver availability for your specific OS version prior to ordering.
Installation Notes
Install into any available PCIe x1 or larger open-ended slot with the system powered off. ST fiber connectors are twist-lock — seat and rotate until secure to avoid intermittent link loss. No external power connector is required; the card draws from the PCIe slot. Ensure the host chassis provides adequate airflow around the card for reliable long-term operation.
