Arista Networks QDD-400G-FR4 versus LINK-PP LQD-CW400-FR4C:
LINK-PP-published compatibility claim for an OEM-coded LINK-PP configuration; OEM approval and universal drop-in suitability are not established. Form factor/speed: QSFP-DD 400G. Source standard: 400G-FR4. Listed temperature options: Commercial. DOM: Yes. Listed coding options: CMIS 4.0/5.0 Multi-Vendor Coded. Confirm the exact ordered suffix/temperature grade; the options column does not establish that the printed C-suffix model is industrial-rated. Verify exact host and NOS release, EEPROM/CMIS coding, port mode, optical standard, reach, fiber/connector, power, temperature, DOM and compatible FEC at both ends. Reverse lookup does not establish symmetric replacement. No OEM-to-OEM or transitive equivalence is inferred.
