FAQ
What type of SFP modules are compatible with this network card?
The ADD-PCIE-2SFP supports standard SFP (Small Form-factor Pluggable) transceiver modules that are compatible with Gigabit Ethernet over fiber optic cables. You can use either multi-mode or single-mode SFP modules depending on your fiber cable type and distance requirements. The card works with SFP modules supporting 1000Base-LX for long-wavelength (1310nm) single-mode fiber and 1000Base-SX for short-wavelength (850nm) multi-mode fiber applications.
What is the maximum data transfer rate of this Ethernet card?
This dual-port Gigabit Ethernet card has a maximum data transfer rate of 8 Gbit/s. This represents the aggregate bandwidth available across both ports when operating simultaneously at full Gigabit Ethernet speed. Each individual port supports standard Gigabit Ethernet rates of 1000 Mbps, with the PCI Express 2.0 x4 host interface providing sufficient bandwidth to handle traffic from both ports without bottlenecking.
Does this card include both half-height and full-height brackets?
Yes, the ADD-PCIE-2SFP package includes both half-height (low-profile) and full-height mounting brackets. This dual-bracket inclusion ensures compatibility with various computer chassis types, from compact small form factor systems that require half-height brackets to standard desktop towers and servers that use full-height brackets. You can select the appropriate bracket during installation based on your specific computer case requirements.
What operating systems are supported by this network interface card?
While specific driver availability depends on the operating system version, the Intel 82576 chipset at the heart of this card has broad driver support across major operating systems. This typically includes various versions of Windows (such as Windows 10 and 11), Linux distributions, and other server operating systems. For the most current driver information and compatibility details, check the manufacturer's website or your operating system's hardware compatibility list.
What is the advantage of using fiber optic connectivity instead of copper?
Fiber optic connectivity offers several advantages over traditional copper Ethernet, including longer maximum cable distances (up to several kilometers with single-mode fiber), complete immunity to electromagnetic interference (EMI), and enhanced security since fiber cables don't emit detectable signals. This makes the ADD-PCIE-2SFP ideal for connecting equipment across different rooms, floors, or buildings, or in environments with significant electrical noise that could degrade copper cable performance.
Can this card be used in servers for network redundancy?
Absolutely. The dual-port design of the ADD-PCIE-2SFP makes it well-suited for server network redundancy configurations. You can configure the two ports for failover operation, where if one network connection fails, traffic automatically switches to the second port. Alternatively, you can use the ports for load balancing to distribute network traffic across both connections, or dedicate each port to different network segments or VLANs for traffic separation in virtualized server environments.
