Allied Telesis AT‑2711FX/SC Network Adapter

The Allied Telesis AT‑2711FX/SC is a high‑performance, single‑port fiber network adapter designed for enterprise and data‑center environments. It delivers reliable 100 Mbps Fast Ethernet connectivity over an optical interface, making it ideal for connecting servers, switches, or storage arrays that require low‑latency, high‑bandwidth links without the need for copper cabling.

Key Technical Specifications

• Interface Type: 100 Mbps Fast Ethernet (100Base‑FX) over a single fiber channel.
• Connector: SC optical connector, compatible with standard SC transceivers and media converters.
Host Interface: PCI Express x1, supporting both legacy PCIe 1.0 and newer PCIe 2.0/3.0 slots for backward compatibility.
• Form Factor: Low‑profile (LP) design with a compact footprint of 69 mm height × 77 mm width; weighs only 50 g, making it suitable for space‑constrained racks.
• Operating Temperature: 0 °C to 50 °C; storage temperature range from –25 °C to +70 °C.
• Humidity Tolerance: 5 %–90 % relative humidity, ensuring stable operation in varied environmental conditions.
• Power Management: Supports flow control and standard Ethernet power‑over‑Ethernet (PoE) features where applicable.

Software & Compatibility

The adapter is fully supported on both Linux and Windows operating systems. Kernel drivers for Linux provide seamless integration with network stacks, while Windows offers robust driver support through the standard NIC interface. The device also supports SNMP for secure network management and monitoring.

Security & Compliance

Manufactured in compliance with RoHS (Restriction of Hazardous Substances), the AT‑2711FX/SC eliminates hazardous materials such as lead, mercury, cadmium, and certain flame retardants. This ensures environmental safety and facilitates easier disposal or recycling.

Performance Features

• Fast Ethernet (100 Mbps): Provides a reliable, low‑latency link for high‑throughput applications such as file transfers, database replication, and virtualization traffic.
• VLAN Tagging: Supports IEEE 802.1Q VLAN tagging, allowing network segmentation and isolation without additional hardware.
• LED Indicators: Built‑in LEDs display link status, activity, and error conditions for quick troubleshooting.
• Flow Control: Hardware flow control prevents packet loss during congestion by signaling the sender to pause transmission.

Installation & Physical Integration

The adapter’s low‑profile design fits into standard PCIe x1 slots on servers, blade chassis, or rack‑mount systems. Its 69 mm height and 77 mm width ensure it can be installed in tight spaces without requiring additional clearance. The single SC fiber port is mounted flush with the rear panel, allowing straightforward cable management.

Use Cases & Applications

• Data Center Interconnect: Connects servers to high‑speed storage arrays or switches over optical links, reducing copper cabling clutter.
• Virtualization Platforms: Provides dedicated network paths for virtual machines, ensuring consistent performance and isolation.
• High‑Availability Clusters: Supports redundant fiber connections in HA setups, improving fault tolerance.
• Industrial Automation: Operates reliably within temperature ranges common to industrial environments, making it suitable for factory floor networking.

Design & Build Quality

The AT‑2711FX/SC features a robust metal chassis that protects the internal circuitry from mechanical shock and vibration. Its compact size reduces cable clutter while maintaining high signal integrity over optical media. The adapter’s low power consumption aligns with energy‑efficient data center designs.

Conclusion

The Allied Telesis AT‑2711FX/SC is a versatile, reliable fiber network adapter that delivers 100 Mbps Fast Ethernet performance in a compact, low‑profile package. With comprehensive OS support, VLAN tagging, SNMP management, and RoHS compliance, it meets the demands of modern enterprise networking while simplifying deployment and maintenance.
