Realtek 8111F Gigabit Ethernet Controller

The W-E1000 SPCI-E Expansion Card uses the Realtek 8111F chipset to provide wired Ethernet connectivity for compatible computer systems.

For B2B buyers, the controller chip is an important specification when evaluating a network expansion card because it helps identify the card platform and expected compatibility.

The Realtek 8111F-based design supports 10 Mbps, 100 Mbps, and 1000 Mbps network environments, making the W-E1000 suitable for systems that need flexible Ethernet connectivity across multiple network speeds.

10/100/1000 Mbps Network Support

The W-E1000 supports three standard Ethernet speed levels.

Network Standard	Supported Speed
Ethernet	10 Mbps
Fast Ethernet	100 Mbps
Gigabit Ethernet	1000 Mbps

Its maximum data transfer rate reaches 1000 Mbps, making the card suitable for Gigabit Ethernet network connections when used with compatible network infrastructure, cables, and devices.

This flexible speed support allows one PCI-E network expansion card to work across different wired network environments.

PCI Express x1 Interface

The W-E1000 uses a PCI Express x1 interface to connect with the host computer.

A PCI Express expansion slot is required for installation. Before ordering, system builders and integrators should confirm that the target motherboard has an available compatible PCI Express expansion card slot.

The PCI Express x1 format makes the W-E1000 suitable for adding an extra network interface to compatible desktops, servers, workstations, and industrial computer systems.

RJ45 Wired Ethernet Connectivity

The card features one external RJ-45 female network port for standard wired Ethernet connections.

This makes the W-E1000 suitable for applications where reliable cable-based network connectivity is preferred, including:

• Desktop network expansion

• Server Ethernet connectivity

• Industrial PC integration

• Workstation upgrades

• Replacement of an existing network interface

• System assembly and maintenance

• Wired LAN applications

The card also supports Auto MDIX, reducing the need to manually distinguish between certain Ethernet cable connection types in compatible network environments.

Full Duplex and Jumbo Frame Support

The W-E1000 SPCI-E Expansion Card supports full duplex communication.

Full duplex operation allows compatible network devices to transmit and receive data at the same time, helping improve communication efficiency compared with half-duplex network operation.

The card also supports Jumbo Frames up to 9K.

For compatible network environments, larger frame sizes can be useful when handling larger volumes of Ethernet data. Actual Jumbo Frame performance depends on the complete network environment, including switches, operating systems, and other connected equipment.

IEEE Network Standards

The W-E1000 supports multiple widely used IEEE Ethernet standards.

• IEEE 802.3

• IEEE 802.3u

• IEEE 802.3x

• IEEE 802.3ab

These specifications cover Ethernet, Fast Ethernet, flow control, and Gigabit Ethernet functionality, helping the card integrate into standard wired network infrastructures.

LED Status Indicators

The W-E1000 includes two LED indicators for quick network status checking:

• 1 yellow Gigabit Detect indicator

• 1 green Link/Activity indicator

These LEDs provide convenient visual feedback about network connection and activity status, which can be useful during installation, troubleshooting, system testing, and routine maintenance.

Physical and Environmental Specifications

The W-E1000 has a compact card design suitable for compatible computer expansion systems.

Physical Specification	Value
Product Length	3.07 in / 78 mm
Product Width	4.7 in / 120.3 mm
Product Height	0.7 in / 18 mm
Operating Temperature	0°C to 70°C
Storage Temperature	0°C to 100°C

These specifications allow system integrators to evaluate the card against available chassis space and intended operating conditions before installation.

Broad Operating System Support

The W-E1000 PCI-E Expansion Card supports a range of Windows, Windows Server, Mac OS, and Linux environments.

Supported software environments include:

• Windows 8 / 8.1 32-bit and 64-bit

• Windows 7 32-bit and 64-bit

• Windows Vista 32-bit and 64-bit

• Windows XP 32-bit and 64-bit
