PCI Express Gen 1.0 max throughput is 2Gbps per lane. PCI Express Gen 2.0 max throughput is 4Gbps per lane. PCI Express Gen 3.0 max throughput is 8Gbps per lane. The available bandwidth (64Gbps) is shared equally between the four ports. Atha, StarTech.com Support **Q: Will this work with single mode gbic's for freebsd?** A: Yes. **Q: Is the open sfp style sfp+? the title says sfp+, but that style isn't specific. there is a difference between them so it should be specified somewhere** A: The PEX10GSFP4I has 4 open SFP+ ports capable of 10Gbps speeds. Stefan, StarTech.com Support **Q: Will cisco sfp-10gb-sr sfp's work in this nic?** A: Yes, we would expect those Cisco SFP modules to work. We’ve specifically tested the card with our version of a very similar SFP-10G-SR module (SFP10GSRST) Curtis, StarTech.com support ## Customer Reviews ### ⭐⭐⭐⭐⭐ Five Stars *by H***F on June 6, 2016* very very good ### ⭐⭐⭐⭐ Four Stars *by A***Y on January 6, 2016* Works out of the box on FreeBSD as an X520-SR2 clone without the hassle of the intel-only transceivers ### ⭐⭐⭐⭐⭐ Review *by A***H on November 16, 2021* Works great in my Dell R810 which I used for my ESXi 6.7 server.
