We are searching for a compatible cable that allows us to connect a Sophos XG Firewall to a Mellanox SN2100. It should be QSFP+ 40GB copper. The list narrows down to just one option on the Sophos side.
Is our assumption right that this cable will be compatible with Mellanox SN2100 as this is a passive copper cable?
Apart from the Cumulus HCL (URL below), we will ensure any Mellanox cable will work on our system. For other cables that have not been tested we cannot guarantee they will work as they have not been tested. Even if the cable is passive copper cable the transceiver still has to interact with the switch. The quality of the cable may vary and it also may not follow standards fully. If your NOS on the switch is Onyx or other, then please use HCL has just reference.
If you run into any problem, please open a case and we can try to assist you.
