Internal Network Card InLine 51125N Fiber 1000 Mbit/s PCI Express

Extensive fibre optic network connectionwith up to 1 Gb/s (fibre)
Supports 1000BASE-SX/LX/BXfor flexible deployment options
Powerful Intel WGI210CS chipsetfor optimum stability
PCIe x1 interfacewith standard and low-profile bracket
Compatible with Windows, Linux, FreeBSDand virtualisation systems

This InLine® Gigabit network card, 1x SFP fibre 1Gb/swas developed for use in desktop, server and embedded systemsand meets modern requirements in terms of energy efficiency, form factor and network stability. It is equipped with an SFP slot that supports various fibre optic transceivers and thus enables flexible network connections over different distances and media types.

By supporting current network protocols and functions such as VLAN tagging, flow control, jumbo frames or checksum offloading, the card is suitable for both standard networks and specialised applications, such as audio-video transmission in accordance with IEEE 802.1Qav. The card is installed via a PCIe slot (PCI Express 2.1), allowing it to be easily integrated into existing systems.
Technical data:

Bus type: PCIe v2.1 (5.0 GT/s) x1 lane
Data rate: 1 Gb/s (fibre)
Chip set: Intel WGI210CS
Supported protocols: IPv4, IPv6
Dimensions: 96 mm x 62 mm (PCIe board)

Supported network modes:
The card can use various fibre optic connections, including:

1000BASE-SX (multimode): For short distances with light signals.
1000BASE-LX (singlemode): For longer distances with a thinner optical fibre.
1000BASE-BX (singlemode WDM): For special applications where uploads and downloads run over a single fibre.

Supported interfaces:

Serializer-Deserializer (SerDes) for 1000BASE-SX/LX (optical fibre - IEEE 802.3)
Serialiser-Deserialiser (SerDes) for 1000BASE-KX (IEEE 802.3ap)
1000BASE-BX (PICMIG 3.1) for gigabit backplane applications
SGMII (Serial-GMII specification) interface for SFP (SFP MSA INF-8074i)/external PHY connections


Supported network functions:

IEEE 802.3x Flow Control: Helps to avoid data congestion in the network.
IEEE 802.1q VLAN: Makes it possible to divide a network into several virtual networks.
Receive-side Scaling (RSS): Distributes incoming network data to multiple CPU cores for load balancing and better performance with multi-core processors.
Jumbo frames up to 9K: Allows larger data packets for more efficient transmission.
Checksum Offloading: Relieves the processor when calculating checksums to improve performance.

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.

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.
