Does NVIDIA ConnectX-7 (MCX755106AC-HEAT) Support Optical Linkup?

I am using ConnectX-7 (MCX755106AC-HEAT) dual-port QSFP NIC.

I have connected third party 400G QSFP112 LD SR4 optical module to the NIC QSFP port using MPO12 active optical cable.

Using ethtool utility, I can see various speed modes with LR, SR, DR and other ability are listed as supported.

Could you please help clarify the queries listed below:

  1. Does NIC card supports optical linkup ?

  2. How to tune NIC card for optical linkup without ANLT ? Are there mlx commands available to adjust tx-rx parameters manually.

  3. Does this NIC card supports linkup with optical transceivers and cables with ANLT ?

  4. Does the ConnectX-7 NIC support third-party QSFP112 optical modules, and are there any known limitations or issues when using non-NVIDIA optics ?

Thanks
