Network adapter ALLNET PCIe 10G x8 Dual SFP+ Fiber NIC Server Adapter ALL0140-2SFP+-10G

ALLNET PCIe 10G x8 Dual SFP+ Fiber NIC Server Adapter ALL0140-2SFP+-10G is a high-performance server network adapter that adds two 10 Gigabit SFP+ fiber ports via a PCI Express x8 slot. Designed for data centers and enterprise servers, this adapter delivers dual 10G uplinks for latency-sensitive environments and high-throughput applications. The card supports standard SFP+ optical transceivers and provides hardware offload features typical for modern server NICs, enabling stable and predictable network performance for virtualization, storage, and routing tasks.

Advantages

The adapter offers dual 10G fiber connectivity in a single PCIe x8 add-in card, reducing the need for multiple interfaces while preserving server expansion slots. Its SFP+ ports allow flexible use of short-range or long-range fiber transceivers, while the PCIe x8 interface ensures sufficient bandwidth to handle simultaneous high-speed streams. The design emphasizes low latency and consistent throughput, making it suitable for environments requiring reliable networking and efficient CPU utilization through offload capabilities.

Suitable for

• Server uplinks in data centers and colocation facilities
• Virtualization hosts and hyper-converged infrastructure
• Storage area networks (SAN) and backup servers
• High-bandwidth services such as media streaming and data aggregation
• Network appliances, routers, and firewalls requiring optical 10G ports

Key specifications

• Interface: PCI Express x8 (electrical lane usage)
• Network ports: 2 × SFP+ for 10 Gigabit fiber connections
• Supported link speed: 10 Gbps per port
• Form factor: Half-height / low-profile bracket compatible with standard server chassis
• Typical use: Server and data center network connectivity with fiber optics

How to use

Install the adapter into an available PCIe x8 (or higher) expansion slot on a powered-down server, secure the card with the chassis screw, and attach compatible SFP+ transceivers into the card's SFP+ cages. Connect the fiber cables to the transceivers and power on the system. Configure the operating system network drivers and assign IP settings or integrate the interfaces into existing switching or bonding configurations as required by your network topology.

Usage recommendations

Use vendor-supported or community-verified drivers compatible with your server OS to ensure full feature support. Select SFP+ transceivers rated for the required distance and fiber type (single-mode or multi-mode). For redundancy and higher aggregate throughput, consider link aggregation or bonding and verify PCIe slot bandwidth availability when populating multiple high-speed adapters.
