## Summary description

The InLine 51125N is an internal network card designed for high-speed fiber connectivity. It features a PCI Express host interface and supports a maximum data transfer rate of 1000 Mbit/s, making it suitable for demanding network environments.

## Long description

The InLine 51125N is an internal Gigabit network card with a single SFP fibre port and PCIe x1 interface, designed for desktop, server and embedded systems. It delivers up to 1 Gb/s over fibre and uses an Intel WGI210CS chipset to provide stable, energy-efficient network connectivity. The SFP slot accepts a variety of fibre transceivers (1000BASE-SX/LX/BX) enabling flexible deployments over different distances and media.
Advantages
The card supports standard network features such as VLAN tagging, flow control, jumbo frames up to 9K and checksum offloading, which reduce CPU load and improve throughput. Its PCIe v2.1 x1 form factor with both standard and low-profile brackets allows easy installation into a wide range of systems. Compatibility with Windows, Linux, FreeBSD and virtualization platforms ensures broad software support.
Suitable for
High-speed fibre uplinks in desktops and servers
Audio/video streaming and other IEEE 802.1Qav-relevant applications
Embedded systems requiring a compact PCIe network interface
Environments needing VLAN segmentation and flow control
Key specifications

How to use
Power down the host system, insert the network card into an available PCIe x1 slot and secure it with the supplied bracket (standard or low-profile as required). Install an appropriate SFP transceiver for the chosen fibre type (SX, LX or BX) and connect the fibre cable. Boot the system and install drivers from the supplied CD or vendor website if the operating system does not automatically detect the card. Configure network settings (IP, VLANs, flow control, MTU for jumbo frames) in the host OS or network management software.
Usage recommendations
Use certified SFP transceivers compatible with 1000BASE-SX/LX/BX and follow recommended fibre handling practices. For multi-core systems enable Receive-side Scaling (RSS) and offloading features in the driver to improve throughput and CPU utilization. Ensure the card’s operating temperature remains within the specified range for reliable operation.
