Adapter Asus PCIe Adapter, XG-C100F, 10GBase-T PCIe SPF+ port for Optical Fiber Transmission and DAC cable - 90IG0490-MO0R00

This Asus PCIe adapter is a high-end network card aimed at 10-gigabit connections via fiber optics or DAC cable. It installs in a PCIe slot and gives you an SFP+ 10 Gigabit port in a desktop or server configuration, without unnecessary extras and embellishments. If you want to step out of the gigabit Ethernet realm and utilize serious internal network connectivity, this is a solid foundation. The red design is a bonus if you also want the inside of your case to look tidy and complete.

What you get is a pure 10G SFP+ port that can work with optical modules or DAC cables for low latency and high bandwidth in the local network. This is particularly useful if you are transferring large files, working with NAS, or have several powerful machines that need to communicate quickly with each other. The PCIe interface provides enough “bandwidth” to avoid bottlenecks within the system. The built-in Quality-of-Service (QoS) allows you to prioritize traffic – for example, to give preference to gaming, VoIP, or streaming over background transfers.

• The network card supports transfer speeds up to 10 Gbps, which is a huge leap from standard 1Gbps LAN and makes large file transfers and backups significantly faster.
• It features an SFP+ 10 Gigabit port, so you can use optical modules or DAC cables according to your network infrastructure needs.
• The interface to the motherboard is PCIe, providing high throughput and stable operation under constant load.
• It has 1 SFP+ port, which is more than enough for a workstation, server, or main uplink to a 10G switch.
• Support for 10GBase-LR with 1 port makes it suitable for optical connections over longer distances compared to typical short DAC solutions.
• The built-in Quality-of-Service (QoS) gives you control over traffic priority to reduce latency for important applications.
• The card comes with a 36-month warranty, which is a good period for a component expected to operate 24/7 in a network environment.

It is suitable for users who want 10G connectivity at home or in the office – power users with NAS, small servers, content creators, as well as for smaller businesses that do not want to limit workstations to 1Gbps. If you are looking for just standard internet for browsing and light work, this card is overkill and you won’t notice a real difference compared to a cheaper gigabit option.

The combination of a 10G SFP+ port, PCIe interface, and built-in QoS makes this Asus adapter a practical choice for serious local networks where speed and traffic control matter. If you are building a fast and clean 10G infrastructure, this is a solid piece of the puzzle.
