Lenovo Mellanox 100G QSFP28 to 25G SFP28 Cable Adapter

You've got a 100G QSFP28 port on your switch or NIC and your endpoint is running 25G SFP28. Instead of swapping the whole card, this adapter bridges the gap. Plug it into the QSFP28 cage, connect your SFP28 transceiver, and you're live. No firmware juggling, no compatibility matrix spelunking. Just a clean 100G-to-25G link where you need one

• Adapts a 100G QSFP28 port for 25G SFP28 transceiver use
• Mellanox-designed for reliable signal integrity at both speeds
• Hot-pluggable — no server or switch reboot required
• Eliminates the need to replace a full NIC just for a speed mismatch
