Q: Does this support full throughput for all 4 links simultaneously, i.e. 40gbps tx and 40gbps rx?

The maximum throughput of the PEX10GSFP4I is limited by the bus interface. 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: 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

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?

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
