The Allied Telesis AT-2911SX/SC-901 is an integrated network card with a PCI Express host interface, designed for use in servers and workstations. The device features a fibre optic connection with SC connector and enables a maximum data transfer rate of 1000 Mbit/s. The card is designed for use in wired networks and supports the 1000BASE-ZX cabling technology, which is intended for optical transmission over fibre optic cables. The functions and features in detail include support for Jumbo Frames, which increases efficiency when transmitting large data packets, as well as Quality of Service (QoS) to set priorities for specific data streams. The card also offers data flow control to prevent network overloads and supports management protocols such as SNMP, which facilitates network monitoring and management. The LED indicators provide visual status display, with a Link/Act LED indicating connection status and data activity.

Applications of the AT-2911SX/SC-901 include environments where a stable, highly secure, and high-performance network connection over fibre optic cable is required. This includes, among others, corporate networks, data centres, industrial applications, and installations where transmission over long distances or in electromagnetically disturbed environments is necessary. The card is suitable for use in Windows and Linux operating systems, ensuring broad compatibility with various server and workstation systems.

Technology explained simply shows that the card features a PCI Express x1 interface, which enables high bandwidth and efficient data transfer between the network card and the system bus. The fibre optic SC connector is a standard in fibre optic communication and allows for a secure, interference-free connection. Power supply is via 3.3 V, and the power consumption in standard operation is 9.2 W, representing an energy-efficient design.

Compatibility and accessories refer to support for the mentioned operating systems as well as compliance with IEEE network standards, including IEEE 802.1p, IEEE 802.1Q, IEEE 802.3, IEEE 802.3ab, IEEE 802.3ac, IEEE 802.3ad, IEEE 802.3az, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z. These standards ensure interoperability with other network devices and components. The card is designed for use in office and industrial environments, with an operating temperature range of 0 to 40 °C and relative humidity of 5 to 90 % defining the operating conditions. Storage is possible in the range of -25 to 70 °C.

Installation and mounting is carried out by inserting the card into a free PCI Express slot of the computer. The card is designed as an integrated module, meaning no additional external components are required. Installation is performed using the standard drivers provided by the operating systems or via the diagnostic and configuration software provided by Allied Telesis, which enables detailed tests and analyses.

Operational advantages include high reliability, low power consumption, and support for modern network functions such as QoS and Jumbo Frames. The card is suitable for use in critical applications where a stable and secure network connection is essential. The certifications UL, FCC/EN55022 A, TUV, EN55024, CE, C-TICK, VCCI as well as RoHS compliance confirm adherence to international safety and environmental standards. The card is therefore suitable for use in various regions and industries, including public and regulated facilities.
