It won't work on Intel switches, I don't believe.
Yes, SFP switches are backwards compatible.
It's most likely a transceiver that Cisco doesn't support. You don't mention Cisco switches, but if they have a CLI, you can run a "show interface" command on them. To learn more, look up "transceiver calibrations." If this is the case, the command "service unsupported-" can be used. To ignore the lack of calibration information for that transceiver, type "transceiver" in the command line.

Purchased to connect my POE cameras to my Unifi 16 port POE switch and Unifi 8 port POE switch. Everything worked fine after I plugged it in and the switches recognized the cable.
I have a number of cables from this brand in use with Unifi Switches and MikroTiks, and they all work flawlessly.
For a 7m cable, this was the best deal at the time. I'm using two Mellanox Connectx 2 sfp 10gb cards. The network interface is no longer the bottleneck; the ssds are.
I have it connected to a udm pro via a unifi poe switch with no problems. It's quite effective.
Mellanox ConnectX-compatible 7-meter cable 2 (port cards with dual and single ports).
It's fantastic! I broke a much more expensive SFP DAC cable and bought this as a temporary replacement, but I'll probably use it permanently and buy two more of these at this price, and I'd definitely buy these again and save it for use if another one in my network array fails.
I was able to get the cable to work, but it does not auto-negotiate, so make sure you set the transmission speed manually when using it.
This cable accomplishes its goal without the use of fiber or separate SFP modules, which are both fragile.
