Review: Works and at a great price - This is a great item at a good price. Works as it should and has been reliable! Will buy again for next project build.
Review: Doesn’t work in Cisco C9500-24Q - This doesn’t work in my Cisco C9500-24Q switches. Instead of passing through the transceiver’s details so the switch can identify it and link at 10Gb, it emulates a “QSFP 40G CU1M” at 40Gb and refuses to link up even though there’s appropriate power on the Rx and Tx. I’m really not sure what is going on with the 3rd party market these days, but this is the 3rd brand of this module I’ve tried in a week and none work properly as my official Cisco modules do, or as 3rd party modules from a year or two back do.

## Questions & Answers

**Q: Will sr4 work in a connectx2?**
A: Hello, this 40GBASE-SR4 Module only work with devices with 40Gb QSFP+ ports and cannot run in a connectx2.

**Q: Does this qsfp work with n9k-c93180lc-ex nexus switch?**

**Q: Will the qsa adapter work with mcx354a-tcbt mellanox connectx-3 dual-ports 10gb/s 10gigabit ethernet pci-e nic card?**
A: I think so, I'm using it with a mcx-354a and a passive DAC to my switch. Not sure if mine is -tcbt or not though.

**Q: Is this compatible with a Dell N4064?**
A: Yes, this QSA Adapter is compatible with Dell N4064 when the QSFP port is configured as port split.
