    I'm happy to say that this custom cable worked fine between my Netgear GSM7352 and a Mellanox Connect cx-4 10k PCIe card in a custom server running TrueNAS Core 12.0U3.

    The SFP+ DAC has arrived. Tech support was very helpful in helping me choose the correct transceiver for my setup. I'm waiting for the second Managed Chassis to arrive, hopefully Sunday.

    Used to create a virtual chassis on a pair of Alcatel-Lucent 6900 switches. Working flawlessly so far. Will buy more from QSFPTEK for sure.
