Product information

Description

The InLine 51125N network interface card is a reliable internal expansion component designed to connect desktop computers and servers to wired fiber optic networks. Equipped with a PCI Express host interface and a 1Gb/s SFP fiber optic connector, this network card delivers stable data transmission speeds. It incorporates the Intel WGI210CS chipset and supports standard networking protocols such as IEEE 802.1Q for VLAN tagging and IEEE 802.3x for flow control. The card is compatible with a wide range of operating systems including multiple versions of Windows, Windows Server, and Linux, making it a versatile choice for professional environments.

Advantages

This network card offers significant advantages for environments requiring secure and interference-free wired communication. The fiber optic connection ensures immunity to electromagnetic interference, which is particularly beneficial in industrial or high-density server rooms. Support for various fiber optic transceivers allows flexible deployment over both short and long distances. Additionally, features like jumbo frames, checksum offloading, and receive-side scaling help optimize system performance by reducing CPU overhead during data processing. The inclusion of both standard and low-profile brackets ensures physical compatibility with various chassis designs.

Suitable for

  • Expanding professional desktop and server environments with fiber optic connectivity
  • Integrating workstations into secure corporate networks requiring VLAN support
  • Setting up wired network connections over extended distances using multimode or singlemode fiber
  • Upgrading systems with high-density server racks using the included low-profile bracket

When it may not be suitable

This network card is not designed for standard copper-based Ethernet connections, as it exclusively features an SFP fiber optic interface and does not include an RJ45 port. It is also not suitable for casual home users who do not have compatible fiber optic infrastructure or SFP transceivers already available.

Key specifications

  • Host interface: PCI Express
  • Connectivity technology: Wired
  • Interface type: Fiber optic SFP connector
  • Data rate: 1 Gb/s
  • Chipset: Intel WGI210CS
  • Networking standards: IEEE 802.1Q, IEEE 802.3x
  • Dimensions: 96 mm x 62 mm
  • Supported operating systems: Windows 7, 8, 10, 11; Windows Server 2008 R2, 2012, 2016, 2019, 2022; Linux kernel 2.6.30 and newer; FreeBSD; VMware ESXi

How to use

To install the InLine 51125N network card, power off your computer or server, disconnect it from the power source, and open the computer case. Insert the card firmly into an available PCI Express x1 or higher slot, securing the bracket to the chassis using a screw. Insert a compatible SFP fiber optic transceiver into the slot on the card and connect your fiber optic cable. Close the case, reconnect the power, and start the system. Install the appropriate drivers for your operating system from the provided media or the manufacturer website to complete the setup.

What to consider before purchase

  • Ensure your system has an available PCI Express slot compatible with the card dimensions
  • Verify that you possess a compatible SFP transceiver and fiber optic cable for your network setup
  • Check that your operating system version is supported by the hardware drivers
  • Determine whether your physical enclosure requires the standard bracket or the included low-profile bracket

Usage recommendations

For optimal network performance and stability, ensure that you use certified SFP transceivers matching your cable type, whether multimode or singlemode, and keep your system drivers updated to the latest stable release provided by the manufacturer.
