Is there a suitable adapter cable for connecting OSPF to QSFP ports? I would like to use a ConnectX-7 OSFP card into a Cisco C9500 switch which has QSFP/100G ports.
There is no direct NVIDIA adapter cable solution for connecting OSFP to standard QSFP28/100G ports. The ConnectX-7 OSFP card uses 100G-PAM4 modulation (4x100Gbps channels) which cannot downshift to the 25G-NRZ modulation used by standard QSFP28 100G ports. These modulation types are fundamentally incompatible.
