## Description

Controller: Intel Ethernet Controller I210-AS. The Ethernet Server Adapter compatible with Intel I210 is specifically designed for high-performance network devices such as servers, with features such as low power consumption, high performance, and stability. It is suitable for various operating systems and can be used in a wide range of applications. Data Rate Per Port: 1.25Gbps/1Gbps/100 Mbps/10Mbps. 1.25g SFP-Port network card with VLAN tagging transmission rate can reach up to 1.25Gbps,and it also supports 10/100/1000Mbps speed and is backward compatible with these transmission rates. It can automatically adapt to different speed network environments, providing efficient, stable, and reliable network connectivity. Supported Operating Systems: Widows 7/8/10/11, Windows Server 2008 R2/2012 R2/2016/2019/2022, VMware ESX/Esxi 5/6/7, FreeBSD 7/8/9/10/11/12/13 ,Linux kernel 2.4.x, 2.6.x, 3.x, 4.x, and 5.x (including most distributions such as Ubuntu, CentOS, and Debian) , SUES 11/12/15, etc. Interface: PCI-E 2.1 x1/x4/x8/16 slot Port: 1 x Fiber Optic SFP Connector:1Gb/s SFP transceiver module/DAC/AOC Support: DCB,SR-IOV, RSS, TCP/IP, WoL, PXE and ISCSI,PCoE and VMDq Support IEEE 802.3az EEE, IEEE 1588 PTP,IEEE 802.1Q for increased efficiency and reduced power. The difference between RJ45 and SFP Port for I210 NIC The RJ45 interface is typically used in Ethernet LANs and Internet access scenarios. Its advantages include easy installation, configuration, and maintenance, as well as wide compatibility with most networking devices such as switches, routers, and computers. The SFP interface is suitable for long-distance transmission, high-speed data transfer or special network environments (such as fiber optic networks). The SFP interface can use various types of optical modules, supporting different types of fiber and transmission distances. Package Contents: 1 x 1.25GbE Ethernet Server with Full height Bracket 1 x Low-profile Bracket

Review: Works only with a transceiver - I put this card in my five-year-old Dell Windows 11 desktop in order to take advantage of fiber internet speeds. You'll need to pair it with an SFP+ R45 transceiver to use it with Ethernet. I used a transceiver from 10Gtek and it's working great. You'll also need the latest X520 driver pack from the Intel website; I used v29.4. The auto-install didn't find the NIC so I used Device Manager's Update Driver function and pointed it to the folder where I'd unzipped the driver, and it installed fine.
Review: Works great - Works perfectly in Windows 11 and doesn't seem picky with sfp+ modules. You do have to install the driver manually but for the price I can live with that.

## Features

- Compatible with I210-AS, the networking adapter transfer rate can reach up to 1250Mbps, is a flexible adapter for your networking requirements.
- Port: Sinlge SFP. Can be connected with 1Gb/s SFP transceiver module/DAC/AOC for meeting the demands of data center environments.
- Interface Type: PCIe v2.1(2.5GT/s)x1 Lane,also compatible with x4, x8, x16 Slot. Enable the most cost-effective deployment of 1GbE in the data center.

### ⭐⭐⭐⭐⭐ Works only with a transceiver

### ⭐⭐⭐⭐⭐ Works great
*by C***A on October 13, 2025*

Works perfectly in Windows 11 and doesn't seem picky with sfp+ modules. You do have to install the driver manually but for the price I can live with that.

### ⭐⭐⭐⭐⭐ Worked Right Out of the Box Windows 11
*by J***H on April 30, 2024*

I would give this card 6 Stars if I could. Literally plugged it in and it took right off. Windows 11 recognized the card as a Intel I210 Gigabit Fiber Network Connection. I used an MTXNEO 1.25G 1310NM 20KM DDM SFP module. Interesting these cards do not have a heat sync on the main chip like most Intel cards. However, the Intel I210 card does not have a heat sync either. So absolutely no worries. At the time of this review these cards were selling for $10.99. Let me tell you, this is a steal! I will for sure be purchasing more of these cards. Will let this one run for a while. If it fails within a short period of time I will update my review. For sure not expecting any issues.
