Network adapter ALLNET ALL0141-4SFP+ 10G PCIe x8 quad SFP+ fiber NIC for servers

ALLNET ALL0141-4SFP+ is a quad SFP+ 10G fiber network adapter for servers that installs in a PCIe x8 slot to add four independent 10 Gb/s fiber ports. The card is engineered for environments that require multiple high-speed links, providing low-latency, high-throughput connections suitable for data center switching, server aggregation and storage networks. Its compact PCIe form factor and four SFP+ cages make it possible to increase server network capacity without altering the host chassis layout.

Advantages

The adapter provides four 10G SFP+ ports in a single PCIe x8 card, enabling simultaneous high-bandwidth connections to switches, storage arrays and other servers. It supports standard SFP+ transceivers for flexible use with single-mode or multimode fiber, and the PCIe x8 interface delivers sufficient lanes for sustained 10G throughput on each port. The card's design focuses on predictable performance and compatibility with common server operating systems and virtualization platforms.

Suitable for (tasks / use cases)

• High-speed uplinks in data center servers and top-of-rack aggregation
• Storage area networks and NAS connectivity requiring multiple 10G links
• Virtualized environments and hypervisor host networking
• Server-to-server cluster interconnects with low latency needs
• Network expansion in existing server hardware without changing chassis

Key specifications

• Interface: PCI Express x8 (physical)
• Ports: 4 × SFP+ cages supporting 10 Gigabit Ethernet transceivers
• Link speed: 10 Gb/s per port (SFP+)
• Form factor: Low-profile / standard bracket compatible PCIe card
• Media: Fiber optic (supports appropriate SFP+ modules for single-mode or multimode)
• Use case focus: Server and data center networking, storage and aggregation

How to use

Power down the server and install the network adapter into an available PCIe x8 slot or larger compatible slot, secure the bracket, and replace the server cover. Insert compatible SFP+ transceivers into the card's SFP+ cages, then connect the fiber jumps to the corresponding switch or device ports. Power on the server and verify that the operating system detects the adapter. Install any vendor or open-source drivers if required, configure link aggregation, VLANs or IP settings through the host OS or hypervisor management interface, and monitor link status and throughput via standard network tools.

Usage recommendations

Use certified SFP+ transceivers and appropriate fiber cabling for the required link distances and mode (single-mode or multimode). Ensure the server motherboard provides sufficient PCIe lanes and that BIOS/firmware settings allow full x8 operation. For best performance in virtualized or high-load environments, consider enabling SR-IOV or driver offloads if supported by the host OS and hypervisor.
